Select Committee on Environmental Audit Minutes of Evidence


Memorandum from the Chartered Institute of Environmental Health (CIEH)

ABOUT THE CHARTERED INSTITUTE

  Founded in 1883, the Chartered Institute of Environmental Health (CIEH) is a professional and educational body dedicated to the promotion of the discipline of environmental health and to encouraging the highest possible standards in the training and work of those who practice it. Based in London, it has approximately 9,500 members, most of whom work in local authorities in England, Wales and Northern Ireland. Apart from providing services and information to them, the Chartered Institute also advises government departments on environmental health and is routinely consulted by them on matters relevant to the work of environmental health officers. The Chartered Institute received its Royal Charter in 1984. It has since become a Collaborating Centre of the World Health Organisation.

BACKGROUND

Our focus on noise

  Our interest in noise matters grew around the beginning of the 1960s with the introduction of the Noise Abatement Act 1960 which, following an interim recommendation of the Wilson Committee, provided inter alia that noise which amounted to a nuisance should be a statutory nuisance for the purposes of Pt III of the Public Health Act 1936. Enforced by local authorities, that was replaced by the Control of Pollution Act 1974 (CoPA) and at the same time, the Health and Safety at Work etc Act introduced a responsibility to control workplace noise which continues.

  The CoPA has itself now been largely replaced by the Environmental Protection Act 1990 (the EPA) though some of its provisions, particularly those relating to construction noise, remain in force. The EPA has since been amended significantly by the 1993 Noise and Statutory Nuisance Act, adding noise from vehicles, machinery and equipment in the street to noise emitted from premises to the list of potential statutory nuisances. More recently it has been augmented, with a night noise offence and powers to seize noise-making equipment, by the Noise Act 1996. An increasing variety of other statutes including the new Licensing Act and the Anti-social Behaviour Act also have something to say on the topic of neighbourhood noise and there is an argument that all of these provisions should be consolidated. (One counter-argument is, of course, that this would represent a degree of de-consolidation of some other provisions.)

  The focus of all of these provisions (and the focus of most of the CIEH's members who deal with noise) is on what is sometimes called "neighbourhood noise". Wider than mere neighbour noise (though the terms are often used without precision), this includes noise from local sources such as entertainment venues and small businesses.

  Though the Police have been given some express powers, for example under the Licensing Act 2003, for the most part the responsible authorities for neighbourhood noise are local councils. They have few powers over transport noise, however—none, in fact, over traffic (though planning powers can affect this indirectly), none over aircraft (aeroplanes or helicopters) in flight, and little over trains/stations. Noise control of so-called "Part A" installations under the integrated pollution prevention and control (IPPC) regime is becoming a matter for both local authorities and the Environment Agency as different industrial sectors are brought within it (a phased process due to be completed by 2007).

The health effects of noise

  The locus of public authorities to intervene in noise derives from its potential effects on health in its broad sense. The health effects of noise are divisible into two—auditory and non-auditory. The first are about impairment of hearing and occur almost exclusively in workplace settings. Environmental noise levels do not produce these effects. Non-auditory effects include (most commonly) annoyance, sleep disturbance, interruption of speech and social interaction, disturbance of concentration (and hence of learning and long-term memory) and hormonal and cardiovascular effects, though it is debateable to what extent all of these effects are actually to do with health or, indeed, harmful. Though often suggested, there is, however, no evidence that noise per se induces mental illness, though there is some to suggest that noise-sensitive people are more prone to mental illness and that the effects of noise may be more pronounced in mentally-ill people.

Sources of neighbour noise

  The sources of neighbour noise are many and varied but what people complain about is not what necessarily affects them most.

  The remainder of this memorandum attempts to answer the questions set out in the announcement (12 February 2004) of the Committee's Inquiry. Coming after the Chartered Institute's oral evidence, it should be read in conjunction with that.

Q1:   What is the scale of the impact of these crimes [neighbourhood noise] on the local environment?

  First of all, as far as noise goes, "crime" is too restrictive a term. For the most part, making a noise, even a very loud noise in the middle of the night, is not a crime (though it may well be a tort). There are some exceptions, eg. where a prohibition is in force or operating a loud-speaker in the street outside permitted hours, but as a rule, the criminal law only comes into play when an instruction to stop making a noise is ignored.

  Is that right? Probably yes—our experience is that many perpetrators of noise do not realise the effect they are having (confirmed MORI, 2003) and it is not unreasonable to give them a chance to "pipe down" before exerting the full force of the law. It does, however, mean there has to be someone available to tell them to do so.

  The impact of these incidents, crimes or otherwise, on people is nonetheless difficult to assess. We have some quantitative data, in particular from the CIEH's own unique annual survey, but little qualitative data. What we do have is often difficult to interpret.

  We know, for example, that during 2002-03, the 290 (of 376 = 77%) English and Welsh local authorities which responded to the CIEH survey received between them just over 224,000 complaints of domestic noise along with c. 80,000 of noise from other sources. We understand that noise generates more complaints to local authorities than any other subject. The total number substantiated as statutory nuisances (the intervention threshold), however, was only just over 35,000; while, encouragingly, the total numbers have been fairly static for the past five years (see the bar chart below, taken from the CIEH's draft Noise Management Guide)(following a long, upward trend beginning in the 1970s), the proportion substantiated has dropped from c. 50% to c. 15%. This may be due to lack of evidence where a noise was, actually, a nuisance but there is anecdotal evidence that just as there is now a greater readiness to complain, (encouraged by greater accessibility of someone to complain to) so there is a greater readiness to complain about less serious noises. Verifying this is, however, difficult.

  As for short-term impact, we know something about the daily and weekly distribution of complaints from an analysis carried out by EHOs in the Royal Borough of Kensington & Chelsea.


Figures are for numbers of service requests per hour as % of weekly total.

  This shows peak complaints between 11.00pm and 2.00am on Saturday nights. This is a typical pattern.

  Another indication that the rise in complaints is not reflective of a worsening neighbourhood noise climate comes from the Noise Incidence Survey (NIS)(BRE for DEFRA, 2000) which said that typical outdoor sound levels had actually decreased slightly between 1990 and 2000 (steady in London) although there was an indication of a slight worsening of background levels at night, especially late at night and early in the morning (the "lengthening day" effect—more pronounced in London). The principal culprit, however, was traffic which generates relatively few complaints. Though the contemporary Noise Attitude Survey (NAS) says that whereas 84% of respondents heard traffic noise, and 40% were bothered by it, the reason seems to be that they become habituated to it.

  The same survey nevertheless reported that whereas 57% of residents' home lives were not at all spoiled by neighbour noise (and noise was ranked only ninth overall in a list of environmental problems—below dog fouling, litter and loss of greenbelt land), 81% of them heard noise from their neighbours and 37% were disturbed, bothered or annoyed to some extent. Just last year, a further survey, by MORI for DEFRA provided similar figures, suggesting that some 63% of people hear their neighbours though only 46% of them are annoyed by that (29% overall) and 14% say it is a sufficient problem to affect their lives.

  Around one in 10 people claim to have made a complaint about neighbour noise to someone (noise maker, Police, local authority, landlord) at some time though clearly, nothing like that number is recorded by local authorities (which report an annual complaint rate of only about five in 1,000) and these surveys still tell us little about the quality of the noise experienced—were these people disturbed daily or just once, was it for five minutes or five hours? Objectively, just how disturbing was it? We don't know. What we do know is that neighbour noise is perceived as more annoying because of features such as its irregular nature, that it shows a lack of consideration and that it has no utility. Inability to control it is a key factor. It is regarded as an invasion of privacy. This illustrates the social factors at play here—the perception of noise is not just a matter of acoustics though it does affect different people in different ways—it is often a complaint, for example, that the legislation (because of its origins in the common law of nuisance) takes no account of unusual sensitivities, especially to low frequency noise. Noise complaints are also often bound up with broader, and long-running, neighbour disputes.

  The distribution of noise problems is certainly uneven: "Risk factors" for neighbour noise appeared to include high density housing (especially high-rise flats), rented accommodation and living in areas of deprivation (though that is not borne out by the CIEH's survey). Not surprisingly, people living in detached houses, in rural or suburban areas of mainly owner-occupied housing and in least deprived areas are least bothered by neighbour noise.

What does all this mean?

  In summary, neighbourhood noise is a fact of life for most people (84% to 63%) and doesn't bother them unduly. A significant minority, however, find it annoying to some degree from time-to-time (46% to 37%) though fewer claim it actually affects their lives (-14%). Even fewer have ever complained to anyone (10% of people, ever) while even fewer have felt compelled to complain to their local authority (-0.5% each year).

  Overall, it is not a big problem at population level (hence in the NAS, noise was rated only 9th in the list of environmental concerns) though that is not to say it is not a big problem for those affected, especially if no solution can be found. Local authorities nevertheless spend a lot of time and money on the subject.

Q2:   Has there been a cultural change in attitudes to these kind of crimes and are they being treated more or less seriously than in the past?

  There is a suggestion from the NIS that people are becoming more sensitive. Whereas, as said, daytime noise levels (mainly due to traffic) generally decreased slightly between 1990 and 2000, more people interviewed thought traffic noise had got worse than thought it had got better.

  Another indication of cultural change has been the rise in the CIEH's figures for complaints (though they need to be viewed cautiously). Though this has flattened out, the rise since the 1970s cannot be due solely to a deteriorating noise climate (though that will be true in many individual cases, especially given that this is a survey of complainants) both because it is not supported by the other evidence (NIS found only a 5% increase in respondents adversely affected by neighbour noise between 1990 and 2000) but because of the scale—the number of domestic complaints went up five-fold in 20 years and that is explicable only in terms of a greater propensity to complain. That may be part of a greater propensity to complain about everything (partly encouraged by more publicity, knowing where to complain, greater accessibility of local authorities etc) or it may illustrate a growing intolerance of noise. That that is part of the picture is, we think, underlined by the decreasing rate of substantiated complaints. Probably, it is both.

  There has certainly been a cultural change by the authorities—by central government and by most local authorities. As for government, the growing body of legislation (see appendix) speaks for itself and DEFRA's current research programme contains no fewer than 22 noise projects. That much of this work may not be expressly tagged as pat of the anti-social behaviour agenda does not mean that it does not contribute to that or that the part played by noise is not being taken seriously. At the same time, DEFRA maintains the Noise Forum as a medium for discussions with a variety of interested parties along with the cross-departmental Noise Research Advisory Committee and the CIEH has for several years enjoyed a particularly constructive relationship with the civil servants responsible for noise and nuisance policy who do appear to have the support of their Ministers. As for local authorities, 10 years ago only 93 councils in England and Wales operated an out-of-hours noise service; today it is 216. According to CIPFA (at 31.3.02) some 9.6% of all environmental health staff time was spent on noise control. This compares to 7.1% 10 years ago. The current cost is c. £48.6 million per annum Though a few local authorities do not seem to take noise as seriously as they might, at least if their ability to return statistics is any guide, most have coped with the rise in complaints without a commensurate increase in resources and the result has been a gradually increasing rate of formal resolutions with numbers of prosecutions, though low in comparison to complaints, remaining historically high and numbers of seizures increasing.

  There are regular complaints that the Courts do not take these cases as seriously as they might but there is little real evidence for that, not least since the results are not collated anywhere and the unique circumstances of each case make them difficult to compare in any event. Recent calls (in the context of "environmental justice") to transfer regulatory appeals, at least those from businesses, to a new Environmental Tribunal, are difficult to justify while there would be disadvantages too and the Magistrates Association has recently issued a sentencing toolkit to its members including information on dealing with noise cases. It might have been improved if they had consulted the CIEH in its drafting but it is a step forward nonetheless.

  Reference is made to the Police role under Q4 below.

Q3:   Do responsible bodies who deal with the problem and its consequences have sufficient resources and powers to do so?

  On the whole, we do think there are sufficient powers to deal with neighbourhood noise, indeed it is difficult to conceive of when one or two might actually be used but our typically incremental approach to such problems means that they are scattered throughout a number of statutes. This means they are less accessible to the layman than they might be. Some have also been a long time coming. We have in mind in particular the latest changes to the Building Regulations which are of crucial importance to the occupiers of new homes, especially when they are to built increasingly to higher densities, and we are dismayed that proposals for post-completion testing have been shelved on promises by housebuilders to improve their performance. The acoustic performance of the existing housing stock nevertheless falls often far short, indeed flat conversions were not covered by Building Regulations at all until 1992, something the consequence of which the government's new Decent Homes standard does nothing to address

  This is not to say that some minor changes (such as attaching fixed penalties to offences under the EPA) might not be beneficial or that some anomalies (such as the availability under the EPA of the "best practicable means" defence to both the service of an abatement notice and to prosecution) might not be cleared up, nor that, despite that we might ask why intruder alarms need be audible at all, the alarm provisions of the 1993 Act should not yet be brought into force. Nor is it to say that we are not concerned that existing powers are being constrained with the emergence of new legislation bringing unintended barriers to the control of noise. We have in mind here, for example, the Human Rights Act which we understand is dissuading some Magistrates from issuing Warrants to EHOs to enter premises to disable alarms on the ground that to do so would be an invasion of privacy. We might mention too the Regulation of Investigatory Powers Act (RIPA) which appears to classify noise monitoring as "surveillance" and on one reading might prevent the tape recording of noise, hitherto a common technique. Some apparent inconsistency of advice by the Surveillance Commission is unhelpful here.

  But if the powers are broadly adequate, local authorities' resources are constantly stretched. Noise investigation is a skilled business requiring properly trained, experienced officers and, sometimes, sophisticated equipment, often carried out at unsocial times. Maintaining a 24/7 noise service can be expensive and, even where that might be objectively justified, authorities may decide they have other spending priorities while a downgrading of the importance of environmental health in many local authorities in recent years often leaves no-one at the top level of management to argue the case anyway. The same staff are, in any event, often responsible for other pollution control functions such as the remediation of contaminated land and the control of atmospheric emissions from industry and we have a sense that different parts of government are often competing for their limited time. A better overview of government's demands on local authorities would be helpful. There is a tendency for resources and management attention to follow indicators and the case for more resources for noise control is moreover weakened by the lack of a performance indicator for noise which might be reflected in an authorities' Comprehensive Performance Assessments.

Q4:   Is there sufficient dialogue and co-operation across government and amongst the various bodies responsible for dealing with the problem at a local level?

  As government outsiders, this is difficult for the CIEH to answer but noise is an issue in one way or another for most government departments and dialogue between them appears generally to be good. An example would be in the Noise Research Advisory Committee of which the CIEH is the only NGO member though the Home Office and the Department of Health seem not to be regular attendees. The CIEH understands that DEFRA was not consulted by the Home Office when the RIPA was being drafted; certainly the CIEH was not consulted about it and the difficulties now being felt for noise investigations might have been avoided if we had been. The relationship between DEFRA and the devolved administrations in Scotland, Wales and N Ireland also appears to be close and constructive.

  Co-operation between local authorities and the Police is as important as it is, unfortunately, variable. While when Police assistance may be needed by EHOs to effect seizures of noise equipment or to deal with noisy parties, help is normally forthcoming, subject to more urgent demands, from the local level, the Police service at the organisational level is more reluctant to be involved. Examples of that can be found in the discarding by the Metropolitan Police of keyholder information which owners of intruder alarms in London are required to deposit with the Police; we understand that it is a similar reluctance on the part of provincial forces to keep this information which has prevented the introduction of a like requirement under the 1993 Noise and Statutory Nuisance Act elsewhere in the country. London local authorities have recently reported similar difficulties accessing details of the keepers of vehicles via the Metropolitan Police. The re-writing of the CIEH's "Police Liaison Guide", first produced at the suggestion of the government's 1993 Neighbour Noise Working Party had to be postponed last year when ACPO was unable to nominate a representative to take part.

Q5:   What alternatives exist for dealing with these types of crimes outside the criminal justice system?

  Most neighbourhood noise is, in fact, already dealt with informally, albeit against a statutory background (in particular of the Environmental Protection Act) whose enforcement provisions are criminal in character. Consistently, the great majority of complaints are resolved with a "quiet word" (though that option is not, in fact, recognised by the Act) and, even when the formal process is invoked in the form of abatement notices, it is still only when they are ignored that criminal sanctions might be applied. The CIEH supports this model which has been replicated more recently under the Noise Act. In both cases nevertheless, the (temporary) seizure of noise-making equipment can provide an effective remedy short of recourse to the courts.

  Similarly, the newer anti-social behaviour orders are available in principle to help deal with persistent noise makers though we have no data to say how many have been issued in this context. Like abatement notices, sanctions only come into play when these orders are broken.

  As the question implies, however, we do not believe that the criminal law provides either the most appropriate or the only tools in many cases. Neighbourhood noise problems are frequently a product of many factors including spatial planning, housing design, conflicting lifestyles etc and they need a combination of education, better social controls, design, insulation etc factors to combat them.

Q6:   DOES LOCAL ENVIRONMENTAL CRIME HAVE A DISPROPORTIONATE IMPACT ON POORER AND LESS ADVANTAGED SECTIONS OF SOCIETY?

  A survey by MORI for DEFRA last year would suggest that noise does have a greater impact on poorer sections of society, highlighting living in a deprived area as a risk factor for self-reported neighbour noise. Insofar as neighbourhood noise is usually traffic dominated, other work for DEFRA linking traffic emissions with deprivation would support this indirectly and there is a striking similarity in the London air quality and ambient noise maps. Ambient noise levels are not, however, high for most people, even in deprived areas, nor do they actually reflect individual noise exposure well and the same relationship between deprivation and noise is not seen in the CIEH's surveys where deprived areas are as likely to show low rates of complaints as they are to show higher rates. Whether environmental noise is a cause or effect of broader environmental degradation is a moot point but there is no obvious causal relationship between noise levels and, for example, graffiti or litter.
