A new smartphone app developed by the National Institute for Occupational Safety and Health (NIOSH) can help dentists measure sound levels in the workplace and collect noise exposure data.
The NIOSH Sound Level Meter app for iOS devices is free to download through iTunes.
NIOSH said the app is not meant to replace professional sound level meters or noise dosimeters or to be used for compliance purposes. To take proper noise measurements, the organization recommends using an external microphone that can be calibrated with an acoustical calibrator.
