Bruel & Kjaer Matron 3 Noise Nuisance Recording Kit

B&K 2250 : Matron 3 - Neighbour Noise Nuisance Monitoring System	£ 35 a day *

The Bruel & Kjaer Matron 3 was based on years of experience with its predecessors to take care of your more difficult and time-consuming noise investigations. The complainant controls the audio recording of the noise, while a Class 1 sound level meter continuously measures and stores noise results for comparison before, during and after the complainant initiated audio recordings.

Uses and features
Description
The standard briefcase contains a second lockable Matron case - the noise monitoring and recording system. This means that you arrive and leave with the same case, avoiding the neighbours suspecting anything.

The inner case contains the noise monitoring system - a precision logging sound level meter complete with audio recording to memory card.

A extension cable is provided for remote positioning of the tripod-mounted microphone and a simple hand-switch allows the complainant to start and stop the audio recording process. A clear indicator on the hand-switch lights to confirm that recording is in progress.

The system is calibrated and, if required, the operator can choose to set the pre-trigger audio recording time, timed audio recordings and post-trigger audio recordings. The case is then locked to prevent any interference with the calibrated instrumentation.

The logging sound level meter can be set to automatically store A-weighted noise analysis parameters and (optionally) frequency analyses at regular time intervals.

The sound level meter records synchronised time and date information along with the noise results and the audio recordings so that comparisons of results may be made before, during and after the complainant-activated recordings.

The Matron 3 system has three main parts

Order the complete Matron 3 system or just any of the component parts.

The microphone system is usually located in the complainant's house. However, it can be positioned externally using a longer microphone extension cable and an Outdoor Microphone Kit UA 1404.
