The SoundEar3-320 is an indoor noise meter with a digital display that shows noise levels in real time; alternatively, it can display the time or be switched off.
Suitable for industrial environments, hospitals, bars, recording studios and concert halls. Applications include detecting maintenance needs on plant machinery through changes in sound, or saving energy when low noise levels indicate vacant rooms where power can be shut off. It can achieve the optimal sound level for work requiring precision and concentration. 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. Comparing different locations and periods provides an overview of the overall noise situation. Designed to be easy to use, it requires no engineering or acoustics background.
The measuring range is from 30 dB to 120 dB. To set up the SoundEar-320, connect it to a PC to name the device and configure email alerts for excessive noise levels. Monitor noise readings from multiple locations and create automated noise reports; these features require the automation add-on, which lets you send and receive noise data via Wi-Fi or LAN through a micro PC or wireless dongle.
Install in a visible spot on the wall, 8 metres above floor level, on the opposite side of the room from the door, not in a corner, away from any sound-absorbing and noisy instruments.
The internal memory capacity is 16MB; logging can be set to user-defined intervals, and readings can be easily transferred to a PC via USB.
A new outdoor version, the SoundEar3-320IP67 model 3322, is available with an IP67 clear cover, outdoor microphone Type I and software. Connectivity via micro PC, WIFI/LAN.
