Noise pollution control with Acoustical Design
Noise limiters, also known as sound limiters are becoming standard issue in many parts
of Australia when applying for or extending a license in an entertainment venue. Most local authorities
require the installation of an electronic noise limiter in halls, pubs, bars, night clubs, restaurants,
health clubs and other entertainment venues to minimize complaints regarding noise pollution.
Acoustical Design are specialists in the noise control field. We supply and / or install noise limiters
and our technical department will be pleased to offer you advice on the appropriate type of unit for your
particular venue. If required we can carry out the installation for you. Please contact us for a quotation
on any noise control equipment.
The SL2000 has been successfully installed in 1000s of venues internationally. The main control unit, which
is housed in a tough steel case can be fitted at a convenient location out of sight when used with the
optional remote indicator. The remote indicator and remote sound pickup microphone are connected using low
voltage cable for ease of installation. Simple to fit and operate, the SL2000 sound limiter offers the same
features as more expensive systems and is local authority approved. With fully automatic operation, 30 Amp
switching capability and built in fire alarm interface this unit offers straightforward installation and
adjustment at a low price.
The sound level in the venue is monitored by the remote microphone and if the preset level is exceeded the
amber and red LEDs on the unit begin to light sequentially as a warning. If the sound remains too loud for
a period of approximately 10 seconds mains power is disconnected from the sound equipment for 10 seconds and
then automatically reconnected; thus no user intervention is required for operation. The trigger level is
adjustable as is the sensitivity to bass and treble frequencies. Similarly the trigger / reset time period
can be altered if required.
