Another domestic noise complaint.
Domestic noise complaints are on the increase - up 44%
since 1990 according to the Chartered Institute of
Environmental Health's Annual Report 2000.
And most of these complaints require time-consuming investigations
frequently in unsociable hours. Brüel & Kjær has launched its new
MATRON-II system, specially designed to meet the needs of Local
Authorities investigating domestic noise complaints.
Housed in a discreet standard briefcase, MATRON-II greatly reduces
the workload of Local Authority Officers by doing most of the time
consuming work. MATRON-II is capable of monitoring noise for days
on end and provides valuable evidence to help Investigating Officers
take appropriate action.
MATRON-II is perfect for investigation of all types of domestic noise
complaints including loud music, barking dogs, DIY, verbal abuse and
harassment and other anti-social behaviour. The system is designed
to be in line with the "Best Value" concept for total cost of ownership
and is simple to use enabling the equipment to be operated by
The system is installed in the complainant's property with the officer
calibrating the sound level meter, setting the unit to record and locking
the case to prevent any interference with the calibrated instruments.
The microphone is positioned at the point of the alleged nuisance
and the tape can then be operated by the complainant via simple
Ideal for mediation or prosecution cases, MATRON-II recordings are
admissible in a court of law and provide valuable evidence for
Investigating Officers in pursuing noise complaints. The fact that the
system can be operated by the complainant enables Investigating
Officers to avoid many of the difficulties associated with noise complaints,
particularly those taking place during unsociable hours. MATRON-II
offers Local Authorities a highly effective weapon in the battle against
domestic noise complaints.
There are two MATRON-II systems. One comprises a Class 1 sound
level meter, type 2238, a Class 1 calibrator, type 4231, a Sony TCD-D8
digital audio tape (DAT) recorder, simple remote control for recordings,
tripod, microphone extension cables and power supply plus cables.
The second is a similar system without the logging sound level meter
although this type of system must be used with caution. In most cases,
the microphone will be located indoors but may also be positioned
externally using a longer extension cable and a weatherproofed outdoor
microphone kit. Accessories include Windows® based software for
graphical presentation of recorded results and a loudspeaker with
integrated amplifier for playback of recorded tapes.
Brüel & Kjær also provides optional calibration and service support to
ensure the MATRON-II systems continue to operate within specifications.
According to the Chartered Institute of Environmental Health's Annual
Report 2000, local authorities in the UK recorded 115,860 domestic
noise complaints between April 1999 and March 2000, a rise of almost
44% since 1990.
