Loud noise from a disco in a ground floor night club was causing noise nuisance and sleep disturbance in the flats above, even though the ground floor area had been treated extensively with acoustic insulation material to control the sound. The local Environmental Heath Officer required that the company implement sound control measures to abate the nuisance.
We carried out noise and vibration tests to assess the main transmission paths. Then we recommended measures to vibration isolate both types of loudspeaker to considerably reduce the structure-borne noise.
We also recommended use of an acoustic limiter to control the sound, i.e. limit it to a lower level. This would provide several benefits. Firstly, it would control (i.e. limit) the level of airborne sound transmission to the flats. Secondly, it would reduce the risk of bar staff and other workers suffering hearing loss - because there was no control over current sound levels, these workers were being exposed to sound levels well above the legal limit set in the Control of Noise at Work regulations. Thirdly, it reduces the risk of hearing loss for people visiting and dancing at the night club.
