The SoundEar3-310 is for reducing noise levels and ensuring hearing protection is worn in compliance with noise regulations. Helping concentration levels and minimising the risk of hearing impairments. Reducing noise by making it visible is a simple and effective method of control.

When the unit display turns red put on hearing protection, green is shown during monitoring,  yellow when noise is becoming loud and red when the noise is too loud.

The measuring range is from 30 dB to 120 dB. To set up the SoundEar3-310, connect it to a PC and input the dB level where you want the ear to turn red. It is recommended to set the device to turn red at 85 dB, following the noise regulations for wearing earmuffs, this will trigger the yellow warning light on at 80 dB. Noise readings display in real-time on the device and can be monitored from multiple locations using the software, providing an overview of the entire noise situation. Automated noise reports can be generated within the software and emailed according to the desired parameter, for example, one for each shift or each day of the week.

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 materials and noisy instruments.

The internal memory capacity is 16MB; logging can be set to user-defined intervals, readings are easily transferred to a PC using a USB. For communication with building management or control systems outputs can be configured to current loop 4-20mA or 0 to 10V DC.

Suitable for production & manufacturing, warehouses and food processing.

A new outdoor version the SoundEar3-310x, model 3315 is available with an IP67 clear cover, outdoor microphone Type I and software. Connectivity by WIFI/Lan, GSM.
