• Description:
  This study reports on the accuracy of smartphone sound measurement applications (apps) and whether they can be appropriately employed for occupational noise measurements. A representative sample of smartphones and tablets on various platforms were acquired, more than 130 iOS apps were evaluated but only 10 apps met our selection criteria. Only 4 out of 62 Android apps were tested. The results showed two apps with mean differences of 0.07 dB (unweighted) and --0.52 dB (A-weighted) from the reference values. Two other apps had mean differences within +/-2 dB. The study suggests that certain apps may be appropriate for use in occupational noise measurements. [Description provided by NIOSH]
