The SoundEar3-300 is for reducing and controlling noise levels in hospitals. An eye-catching warning sign is displayed in the patient room when the noise limit is breached, serving as a reminder to keep the volume down—improving the wellbeing of patients and staff at hospitals (better sleep, faster recovery, less stress).

The lights on the device can be switched off at night, avoiding sleep disturbance. The measuring range is from 30 dB to 120 dB. To set up the SoundEar3-300, connect it to a PC and input the dB level where you want the ear to turn red. Noise readings display in real-time on the device and can be viewed from multiple patient rooms using the software. Automated noise reports can be generated within the software and emailed according to the desired parameter, for example, one for each shift, for each day of the week or each 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.

Used in; patient rooms, recovery rooms,  operation theatre, intensive care units and neonatal care.

A new outdoor version the SoundEar3-300x, model 3305 is available with an IP67 clear cover, outdoor microphone Type I and software. Connectivity by WIFI/Lan, GSM.
