This precision grade sound level meter is particularly suitable for environmental noise measurement, including BS4142 surveys. With its Class 1 performance, removable microphone stem (can take a microphone extension cable), data storage and automatic timing functions it meets most environmental applications. It is also perfectly suited for the professional acoustician involved in noise at work applications.

Environmental and Community Noise Surveys

The Pulsar 91 meter is ideal for general environmental noise surveys and for BS4142 (mixed residential and industrial) assessments. The ability to measure down to 21 dB(A) makes it suitable for locations with low ambient noise levels. For this type of survey it is often necessary to make repeating, timed measurements (e.g. measure every 15 minutes). The Pulsar 91 can be set to make such measurements, automatically restarting and storing parameters such as LAeq, L90, Lmax, and many others. It also stores the Leq every second, giving a graph of the noise level over time for further reporting and analysis.

Noise at Work Surveys

The European Noise at Work Regulations and HSE's Guidelines (Controlling Noise at Work) require the use of at least a Class 2 Integrating Sound Level Meter. The Pulsar 91 is a Class 1 meter and so is more than adequate. For more information, please visit our Noise at Work information pages.
