OSHA Level (LOSHA) The Average Sound Level calculated in accordance with the Occupational Safety and Health Administration Exchange Rate and Threshold Level. Peak The maximum value of the instantaneous, frequency weighted (C or Unweighted), sound pressure in a given time interval. For the dosimeters, a Peak value is recorded for 2 different time intervals.
Page 91
Projected Sound Exposure Projected Sound Exposure shows what the actual sound exposure will be for a specific time period if the current Equivalent- Continuous Sound Level (L ) remains at its current level. The dosimeters calculate an 8 hour and a 40 hour projected sound exposure.
Page 92
Threshold Level The threshold level is applied in hearing damage risk assessment. According to the ANSI S1.25 standard, it refers to the A-weighted sound level below which the 49.03 degF ft sec dosimeter produces little or no dose accumulation. For that reason, measured sound below this level may be disregarded.
Compliance and Standards Reference C.1 IEC Compliance The Spartan 730 dosimeter complies with the following standards as specified: IEC 61252, IEC 61260-1, IEC 61010 Reference Orientation The unit is angled at about 45 degrees so that the microphone is pointing up.
