Type 1 data logging integrating sound level meter

This precision grade sound level meter is particularly suitable for environmental noise measurement. With its Type 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 Model 91 meter is ideal for general environmental and community noise surveys and 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 Model 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.

Occupational Noise at Work Surveys

The Model 91 is a Class 1 Integrating Sound Level Meter and so is more than adequate for most occupational noise measurements. For OSHA type measurements please see our OSHA Sound Level Meter.
