Noise levels have to be intrusive to fall within the general parameters requiring action under the reference Acts, for example;
Noise and Statutory Nuisance Act (1990)
Deals with noise emitted from vehicles, machinery or equipment in the street, audible intruder alarms. For people living near industrial premises, noise generated by the working practices of the company, or by the volume or nature of traffic visiting the site, can also be an issue.
Noise Act (1996)
Provides local authorities with a procedure for dealing with excessive noise emitted from dwellings at night.
Environmental Protection Act (1993)
Part III of this Act empowers a Local Authority to serve Abatement Notices if it is satisfied that "the noise emitted from any premises is prejudicial to health or a nuisance...". With this the local Environmental Health Officer can require prevention or restriction of the noise being generated and can instruct such work as necessary to achieve a reduction in noise.
In terms of Risk Assessment it is often necessary to review noise levels but in all cases noise can be percussive, random, non-specific patterned, high music levels; rarely is a natural sound considered.
In the case of SCARECROW systems they randomly broadcast natural sounds (bird calls) at a sound level as near natural as the prevailing ambient noise levels permit.
This assumes a carefully designed loudspeaker system under the 'rules' we have published and that the system is commissioned by an engineer Certified by SCARECROW.
