Hire Period:


The SoundEar II Industrial is designed for use in factories and other indoor industrial environments. It can be used to indicate to staff when the sound levels are getting high, prompting them to reduce the noise, leave the area or to fit hearing protection.

The noise limit can be set within the range of 40 to 115 dB(A), adjusted in 5 dB steps using the dial hidden on the back of the sign. The yellow lights warn when the level is getting close to the limit and the red light shows the limit has been exceeded.

SoundEar II Industrial Noise Sign Applications

The SoundEar II Industrial can be installed in almost any indoor environment where employees need to be warned of high noise levels and to take action.

As this noise warning sign is very easy to install, it is ideal for temporary and other short term noise measurement applications.

  • Factories
  • Industrial sites
  • By machinery that makes intermittent noise
  • By machinery with varying noise levels
  • Dusty environments (IP42 rated)

Setting Up

1. Set the sound level using the dial on the back.

2. Hang the sign on a single screw on the wall.

3. Connect the power.

Location and Sound Level

The perfect location for a sign depends on the layout and the acoustics of the area in question. The most important aspect of the SoundEar is that it reminds people to keep the level down, so it is best to mount them where clearly visible to anybody entering the room or area.
