Noise Limiter Calibration

Contact Us

Increasingly Local Authorities require an opearable electronic noise limiter in music entertainment venues. These venues typically include pubs, clubs, karaoke bars, gyms, village halls, places of worship and a host of other venues.

Noise limiters for amplified entertainment systems play an important role when a venue is located within close proximity to noise sensitive properties; which is often the case. Correctly installed and set, the electronic noise limiter will automatically control and limit the maximum level of music played within the premises. This allows the venue to easily operate without causing undue noise disturbance which would otherwise prove difficult.

The local authority need proof that the electronic noise limiter is periodically checked by a competent person, in order to ensure that the limiter adequately control noise emission levels. As such in most commercial venue’s, a yearly calibration and certificate is required by the local authority.

Depending on the type of different noise limiter installed at your venue, they operate in different methods. HA Acoustics are familiar with a wide range of noise limiters and their set-up. The Local Authoruty may set a specific procedure to determine and limit the level. If not, then HA Acoustics experience enables a suitable calibration procedure to be implemented, depending on your venue’s operating days, hours, type of music/entertainment noise, building façade composition and proximity to nearby noise sensitive receivers.

For example, a London Karaoke bar, required assessment after midnight, between lulls in traffic to determine audibility at 1metre from the nearest residential. Whereas, a village hall in Essex required a daytime assessment outside of rush hour, with one of two lobby doors open to determine audibility level at a neighbouring premises.
