The Mayor’s Ambient Noise Strategy Mayor of London 175 schools, to rectify existing acoustic deficiencies. Building Bulletin 93 (see box below) focuses on upper limits for internal levels and sound insulation in new schools, but also recommends upper limits for external noise. Box 51: School acoustic design Existing and new school premises are required to comply with the Education (School Premises) Regulations 1999 (Statutory Instrument 1999 No 2). Building Bulletin 93 13 provides a regulatory framework for the acoustic design of schools in support of the Building Regulations, relevant exemptions from which ended in 2003. BB93 also gives supporting advice and recommendations for school planning and design. The requirements of the Disability Discrimination Act 1995 reinforce the need for good acoustic conditions, as do the requirements of the Special Educational Needs and Disability Act 2001 for integration of children with special needs into mainstream schools. 4F.16 More Government funding is now becoming available for maintenance and improvement works to schools. Acoustic improvement can, however, be complex. Innovations such as ‘School Works’, set up by the Architecture Foundation, have highlighted the impact of design on educational achievement. The work of SENJIT, Institute of Education, University of London, Makeover at School and other organisations is relevant. Environmental education can be integrated with pupil/teacher participation in the preparation of design improvement proposals. Such work in the acoustics field could help busy schools and local education authorities to decide on spending priorities. Some London boroughs already carry out noise education work in schools. Wider activities related to sound and soundscapes (see glossary) would have rich links with many parts of the curriculum, and could help young people to look after their hearing (see paragraphs 5.5-6). 4F.17 The acceptable level of noise depends on the activities within the different parts of the school. Clearly, libraries and areas for formal teaching need quieter conditions than gyms. Some schools may benefit from installation of noise barriers, subject to safety and security issues. Barriers can also reduce the impact of playground noise on the locality. Dense planting within school grounds may also help qualitatively. On some roads near schools, variable speed limits or other traffic measures could reduce noise. 4F.18 Hospitals and other health facilities generate noise, through the traffic they create, including ambulances, helicopters, delivery of supplies, workers and people visiting; and through other activities such as boilerhouses, emergency generators, pumps, workshops, laundries, kitchens and building works. Noise from travel and other activities may be a particular
176 Mayor of London The Mayor’s Ambient Noise Strategy issue in the evening or at night, notably for new primary care facilities in residential areas. Providing high quality health care services for patients also means that noise needs to be controlled, particularly in very noise sensitive areas such as wards, operating theatres, delivery rooms, treatment rooms, examination and consulting rooms, and staff sleeping areas. The National Health Service has its own guidelines for managing noise. Hospitals are exempt from the parts of the Building Regulations dealing with sound transmission in buildings. Health Technical Memorandum 2045 14 gives advice and guidance to healthcare management, design engineers, estates managers and operations managers on legal requirements, design implications, maintenance and other measures. Environmental noise criteria for noise emissions from hospital developments are typically specified by local planning authorities for site boundaries, following guidance in PPG24. policy 71 policy 72 The Mayor will urge the Government to provide an effective framework of regulation, enforcement, information and resources for external and internal noise insulation in support of trends towards higher density housing and mixed-use development. Elements include: ■ Rigorously monitoring implemention of Building Regulations on sound transmission. In particular, if ‘Robust Standard Details’ are used, requiring an element of independent on-site acoustic testing to ensure that constructions do in practice always meet or exceed the necessary standards, and ensuring provision of suitable information to purchasers; ■ Including noise in Decent Homes criteria, the new Housing Health and Safety Rating System (HHSRS), and other mechanisms, in such ways as to ensure effective action to target the worst-affected housing; ■ Support for training and information on practical noise reduction in housing for building trades, materials and equipment suppliers, landlords and occupiers. The Mayor will urge boroughs and other social housing providers to, where practicable and cost-effective: ■ Demonstrate good acoustic design practice both in new housing, and in regeneration, refurbishment and maintenance, with particular regard to courtyard remodelling, replacement window programmes, and internal sound insulation; ■ Provide information on practical noise reduction in both existing and new housing for landlords and occupiers; ■ Integrate action on noise as far as possible with programmes to address fuel poverty.
