School Music Room. 
A school needed to ensure that students hearing was protected whilst
playing music in the practice rooms. Musicians were to be given a visual
warning when the sound level exceeded 85dB and if the level was not
reduced within 10 seconds the power supply to their instruments was to
be cut off for a period of 10 seconds and then restored automatically.
Lime Technologies recommended the
SL2000
noise limiter with the optional
bright compact remote display. The products were fitted by the
schools usual electrical contractor with the aid of the comprehensive
instructions supplied. The main control unit was fitted, out of sight at
a convenient location to connect to the existing mains wiring and the
display was fitted at high level in the practice room where it could
easily be seen. The
remote microphone was concealed behind a ventilation grill in the
suspended ceiling in order to prevent tampering.
Night Club Smoking Terrace.
After the introduction of the smoking ban a night club provided an
outside smoking area for its customers. Unfortunately loud conversation
late at night caused disturbance to nearby residents. A visual warning
was required in order to alert door staff if the noise level on the
smoking terrace exceeded 80 dB so that they could ask customers to talk
more quietly. A
noise activated warning sign would have been the lowest cost option
but the night club management wanted an early warning to give door staff
the opportunity to tackle the problem in a more subtle way. Lime
Technologies supplied a
Sentry noise limiter with an additional rotating beacon warning
light and the
Lime Technologies external microphone. Being water resistant the
microphone could be permanently fitted outside on the terrace. The trip
level for the beacon was set to 80dB but the noise limiter also provided
an LED bargraph display from 70dB for advanced warning of potential
problem.
Wedding Venue Noise Problem.
A wedding venue had had complaints from neighbours due to excessive
noise levels from live bands and DJs. The music was played at various
locations throughout the venue including a marquee in the grounds. The
Lime Technologies plug and play noise limiter was the ideal
solution. As a portable unit it could easily be relocated to any point
that music was played. It could be set, using a decibel meter to provide
a visual warning when the sound level at the neighbours property
exceeded 45dB and to cut off mains power from the performers equipment
if they continually ignored the warning lights.
Urgent Requirement For A Pub.
A pub in a residential area was about to be banned from playing music
due to a number of complaints regarding noise. They needed a noise
limiter urgently so that a planned event could go ahead the following
evening. Lime Technologies supplied a
plug and play noise limiter on a next day delivery preset to the
required 85 dB level. The unit was ready to plug in and required no
professional installation. A locking mains socket cover was provided to
prevent bypassing of the noise limiter.
Metalwork Fabrication Area.
A small business which manufactured custom metal products had
certain machinery / processes which produced a noise level of more than
85dB. Employees did not wish to wear hearing protection when
unnecessary but the management had to comply with health and safety at
work regulations. A
noise activated warning sign, supplied by Lime Technologies was
fitted in the affected area. The sign would illuminate
automatically when the noise reached a level which could cause hearing
damage and workers would be alerted to the fact that hearing protection
should be worn. |
