Dose Calculation Meter Mobile Application

Model: Dosimeter

  • Tap the wrench icon to bring up the Setup page, and select between ISO, OSHA HC, OSHA PEL, and NIOSH
  • Criterion level 85, exchange rate 3.0, SPL Leq, A weighting
  • There is no threshold, so all sound contributes to dose, although low SPL levels do not add much
  • One of the methods used in the USA, and it is based on allowing 90dBA exposure over 8 hours
  • Uses a 5dB exchange rate, so as sound increases 5dB the length of time to 100% dose is halved

Product Info

A Dosimeter measures a person’s cumulative noise exposure over time. It was designed to help prevent hearing loss by allowing a user to monitor the amount of noise that they have been exposed to, which over time can correlate to hearing damage. In addition to the Dose calculation, we have added a separate SPL Meter to this screen. This is not required as a part of the specification, and the SPL Meter settings do not change the way that the Dose is computed. Although this SPL Meter is not required by the regulations, we have included it to provide another useful for metric for alerting the user to exposure to loud sounds. Think of it like running an SPL Meter and a Dosimeter at the same time.

  • One of the methods used in the USA, and it is based on allowing 90dBA exposure over 8 hours
  • Uses a 5dB exchange rate, so as sound increases 5dB the length of time to 100% dose is halved
  • Uses a weighting and Slow decay with a threshold at 80dB
  • Used in the USA, and it is also based on allowing 90dBA exposure over 8 hours
  • Very similar to OSHA, although it uses an 85dBA normal exposure level, and a 3dB exchange rate
