Noise from neighbours, vehicles and from within buildings can be a nuisance, in some cases cause unnecessary stress.
Laid out under the Building Regulations Approved Document Part E are standards outlining the performance of buildings to limit ‘airborne’ and ‘impact’ noise transmission.
The regulations have introduced pre-completion testing (PCT) for sound insulation as a means of demonstrating compliance.
Pre-completion testing applies to buildings where there has been a change of use for residential purposes. New build houses, flats and domestic extensions.
This requires that at least 10% of all new residential properties are tested to demonstrate that the required standards have been met.
Pre-completion testing also includes hotels, hostels, student halls of residence and any room for residential use.
The aim of the Control of Noise at Work Regulations 2005 is to ensure that workers' hearing is protected from excessive noise at their place of work, which could cause them to lose their hearing and/or to suffer from tinnitus (permanent ringing in the ears).
Using a noise dose meter, the employee’s noise exposure is accurately logged. The data is then compared with legislative exposure values to determine if the employee has exceeded the noise exposure values (A-weighted) or peak values (C-weighted). The use of suitable hearing protection, such as ear plugs / ear defenders, can also be calculated to ensure the correct equipment is being worn and a suitable level of protection is being provided to the employer.
