A major construction company needed to provide a visual warning of
noise levels on a demolition site to avoid noise complaints from neighbours and
warn operatives when hearing protection was necessary. There was nothing suitable
available so a new product was designed and manufactured to the clients specification.
The CNX Industrial Noise Level Indicator was robust enough to be used on outdoor
construction sites and provided 360 degree mobile visual noise indication. It subsequetly
won an innovation award at the 2014 National Federation of Demolition Contractors (NFDC)
Music noise levels were too high in a community centre with
residential premises above. The centre had a caretaker living in an
adjoining flat so the ILX Noise Level Indicator was the ideal low cost solution.
The main display unit was fitted in a position clearly visible to DJs so
that they were aware of the sound level and an additional warning beacon with
a 10 second time delay was installed in the caretakers flat so the caretaker would
be made aware if the noise level rose above the chosen maximum for a prolonged period.
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
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
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.
Marquee With High Power Requirement
A country house function venue required a plug in noise limiter for use in marquees.
The unit needed to be able to supply 30 Amps at 230 Volts and provide a high visibility warning
to performers. Lime Technologies custom manufactured a device with three 13 amp mains socket
outlets in the front panel together with a 32 amp Ceeform plug and suitable cable. A
flashing beacon was also fitted to improve visibility. The unit was calibrated and tested so that it could be used
on the day of delivery.
