Sentry Music Noise Controller
Automatic Volume Control
Fire Alarm Priority
Loud music in bars and clubs can be a problem to staff and to local residents. The hearing of employees must be protected, and the quality of the environment must be protected for the benefit of anybody living nearby.
We have products available to help with all aspects of Entertainment Noise:
There are two approaches to controlling the sound level from a DJ or live band:
Cutting the power tends to be a favorite with those enforcing the control, as this is more difficult to bypass. Limiting the volume tends to be preferred by those who own the equipment.
We can provide both methods, or a combination of the two.
The most popular option, the Sentry, is installed between the venue's power supply and the outlet sockets. It measures the noise levels, gives a high level warning and then cuts the power if the warnings are ignored.
The Automatic Volume Control connects between the mixer and amplifier. If the volume is increased too high, this unit attenuates it. Although a warning is given on the units display, this attenuation should not be obvious to club visitors.
If you like the Volume Control method but are also forced towards having the ultimate control of cutting the power (live bands with their own equipment for example) then the Sentry can be linked to a Volume Control unit. If the house amplifiers are being used, the Volume Control will keep the volume to an acceptable level. If the Volume Control is bypassed for any reason, the Sentry will give its warning and then cut the power.
Workers in the entertainment industry (bar staff, etc.) should be treated the same as staff in any other industry. Their exposure to noise should be monitored and, if necessary, reduced. This can be done by the usual methods: reduction at source, relocation, staff rotation and hearing protection.
Before making any decisions, a noise assessment should first be carried out using the correct type of sound level meter.
Optimus Red Sound Level Meter
The Optimus Red is a Class 2 Integrating Sound Level Meter, and so is ideal for meeting the OSHA regulations. This meter can be used to measure assess all workers' exposure to noise.
The dBadge Noise Dosemeter is attached to the worker's shoulder and monitors the noise exposure throughout the day. This is often easier than making measurements with a sound level meter and then calculating the exposure.
With the typically high sound levels from music in clubs and pubs, it can be difficult to hear a fire alarm and safety announcement.
The CX4 connects between the mixer and amplifier and interfaces with your alarm system. When the alarm activates, the CX4 reduces the music sound level and provides a priority channel for safety announcements.
