How loud is too loud?

Continued exposure to noise above 85 dBA (adjusted decibels) over time will cause hearing loss. The volume (dBA) and the length of exposure to the sound will tell you how harmful the noise is.

In general, the louder the noise, the less time required before hearing loss will occur.

Sound Privacy

Privacy describes the perceived sound reduction across a wall. Privacy is a function of both sound insulation and background noise. Background noise is made up of services noise and environmental noise sources breaking in through the facade or open windows, vents etc.

If the background noise within a room is increased by 5 to 10 dB, the perceived level of privacy across a partition is also increased by 5 to 10 dB. Therefore, when looking at required sound insulation levels on-site, it is important to consider both the background noise in the receiver room and the sound insulation across the partition.

Reverberation Time

The ‘reverberation time’ of a space changes the way the space ‘sounds’ and can affect the intelligibility acoustic information. A high reverberation time can make a room sound muffled, loud and noisy. Rooms designed for speech typically have a low reverberation time, whereas a higher reverberation time can add depth, richness and warmth to music.

The reverberation time of a room is defined as the time it takes for sound to decay by 60 dB after an abrupt termination. It is linked to the total quantity of soft treatments and the volume of the room.

Noise Disturbance

Building acoustics can help to mitigate the effects of noise disturbance which can have negative effects on health, well-being and general quality of life.

The Noise Policy Statement for England (NPSE) defines noise pollution as:

- Environmental noise: which includes noise from transportation sources. - Neighbour noise: which includes noise from inside and outside buildings. - Neighbourhood noise: which includes noise arising from industrial and entertainment premises, trade and businesses, construction sites and noise in the street.

This can be an important consideration for the location, design and construction of new developments.
