The SoundEar3-320 is an indoor noise meter with a digital display that shows noise levels real-time; alternatively, it can be used to show the time or switched off.

Suitable for industrial environments, hospitals, bars, recording studios and concert halls. Applications include detecting maintenance on plant machinery by changes in sound, or for energy savings when low noise levels indicate vacant rooms where power can be shut off. The optimal level of sound for work requiring precision and concentration can be attained.  A continuous noise monitoring solution which can communicate directly with a building management system using current loop 4-20mA or 0 to 10V DC outputs.

You can analyse the sound data using the software to see peaks and troughs. Produce documentation with the logged data for managing noise levels. Comparison of different locations and periods provide an overview of the entire noise situation. Designed to be easy to use, no background engineering or acoustics is needed.

The measuring range is from 30 dB to 120 dB. To set up the SoundEar-320, connect it to a PC where you can name the device and configure email alerts for excessive noise levels.
