Pre-Completion Sound Testing
Lighthouse Acoustics are a Member of the ANC Pre-Completion Testing Registration Scheme which is approved by the DCLG to undertake sound insulation testing in accordance with the Building Regulations Approved Document E.
All new build or conversion dwelling-houses, flats or rooms for residential purposes (e.g. hotels, student accommodation) are required to have a sound test carried out for airborne and impact sound insulation upon completion, adhering to current building regulations. The only exceptions to this are detached houses or new build developments that have registered with Robust Details scheme.
Airborne Sound Insulation Testing
Should sound transfer through a separating wall or floor construction be the cause of complaint, the first step is to establish the existing level of sound insulation. Airborne sound testing may reveal that the separating construction is the main transmission path or that flanking via the surrounding structures is the cause of the complaint. Once this is established, suitable remedial measures may then be specified.
Should noise break-in via a façade be an issue due to road traffic or other sources, the existing level of sound insulation may also be established. Likewise, should noise breakout via a façade be an issue due to music or other sources, the existing sound insulation level may be established.
Impact Sound Insulation Testing
Should impact sound form the floor above be the cause of complaint, the first step is to establish the current level of sound insulation. Testing may reveal that the separating construction is the main transmission path or that flanking via the surrounding structures is the cause of the complaint. Once this is established, suitable remedial measures may then be specified.
The reverberation time of a space can have a significant impact on speech intelligibility and clarity of music. It can also affect the reverberant sound level within a space which can impact speech privacy within open plan spaces such as offices and the decay of sound across open plan spaces such as workshops. Measurement of the existing reverberation time is the first step in establishing suitable absorbent treatment in order to reduce the reverberation time.
Indoor Ambient Noise Levels
Indoor ambient noise levels can have a significant impact on the occupants of a space. Too high and speech intelligibility may be affected or sleep disturbance may occur. Too low and acoustic privacy may be adversely affected. Measurement of the existing indoor ambient noise level is the first step in establishing suitable mitigation measures.
Building services noise levels can affect internal and external spaces. Whilst a certain level of noise may be expected due to the operation of equipment, if the level is too high it may be considered intrusive or even a noise nuisance. Measurement of existing building services noise levels is the first step in identifying suitable mitigation measures.
