Hearing Protection Warning Sign, Pulsar SafeEar

Wearing hearing protection constantly in work environments is never popular. The Pulsar SafeEar Hearing Protection Warning Sign solves this as it reacts to noise and lights up to tell people when to put on hearing protection and when it's safe to take it off, so the requirement to wear PPE all the time just in case of high noise levels disappears. 

Optional extras include a Hi-Vis Beacon to make the sign even more obvious and a data logger to monitor noise levels over time. 

  • You set the trigger level between 40 dB(A) to 114 dB(A)
  • Lights up a warning message when noise trigger level is reached
