The SoundEar 3 is a data logging Noise Warning Sign that can be mounted on a wall or other vertical surface using a single screw or hook. The trigger sound level is set using the software or buttons on the sign. The green, yellow and red lights can be set to warn people when the sound levels are getting high or already too high. The noise measurements can be downloaded to a Windows computer and reports generated using the SoundEar software that is included.

The SoundEar 3 has a dark gloss finish, making it ideal for use where appearance is important, such as entertainment venues, libraries, hospitals and schools. It mounts on the wall and lights up when the sound levels are too high. The "noise" can be from any source: loud music, machinery, talking, shouting.
The sound level trigger levels can be set using the software. The lights can be set to light up or flash when the sound levels are high, and can have different settings for day or night. Basic adjustments can also be made using controls on the noise sign itself.
The SoundEar 3 is suitable for any indoor area where people need to be warned about high noise levels or reminded to keep the noise down.
After download to the computer, noise charts can be produced clearly showing the changes in sound level over time.
