  • 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.
