    CHAPTER 1: Introduction Dosimetry 1: Introduction Dosimetry Measuring noise in the workplace is an important element of hearing conservation programs and noise reduction programs. With a noise dosimeter, you can assess and determine a worker’s daily exposure to noise levels. This information can be used to ensure compliance with regulatory bodies or to ensure if hearing conservation programs are needed.

  • Page 10: Noise Dosimeter

    1: Introduction Dosimetry Noise dosimeter What is a noise dosimeter and how does it compute measurements? Essentially, a noise dosimeter is composed of the following: a microphone with a preamplifier, a weighted network, fast or slow response time, an internal clock, calculator, and memory to store logged data.

  • Page 11: Range Of Sound

    1: Introduction Dosimetry Range of sound Sound pressure is measured in decibels, or tenths of a Bel. Sound pressure level is indicated as dB SPL. Since the human ear can detect sounds with an extensive range of amplitude, a decibel scale is used to simplify the measurement results. For example, the ratio between the threshold of hearing and threshold of pain in the human ear if measured in true energy is 10,000,000 times! The same range using the dB scale is 0–140 dB referenced to 20 µPa (Micropascals).

  • Page 12: Applications Of The Edge

    1: Introduction Dosimetry Applications of the Edge The Edge has a cable-free, mounted microphone that converts sound pressure into an electrical signal. This signal is conditioned, monitored, and integrated over time in order to provide a host of automatically calculated values that can be used in occupational and environmental noise assessments.

  • Page 69: B: Glossary Of Terms

    APPENDIX Appendix B Glossary of Terms B: Glossary of Terms Background Noise, effects of Background noise can cause considerable error in measurement when its level is high relative to the level of a noise source of interest. If you can make measurements both with and without the contribution of a noise source of interest, you can mathematically subtract the background noise from the combined measurement, yielding the level of the noise source of interest alone.
  • Page 70 Appendix B Glossary of Terms Combining Noise sources Because sound levels are measured in decibels they cannot be simply added together. A sound level of 90 dB plus 90 dB does not yield 180 dB but rather 93 dB. The procedure for mathematically determining a combined level of sound from independent measurements made for two noise sources is given below.
  • Page 71 Appendix B Glossary of Terms Criterion Time The time over which the Criterion Level is established, generally 8 hours. Decibel (dB) Sound Level Meters use the decibel as the unit of measure known as Sound Pressure Level (SPL). SPL uses the ratio between a reference level of 20 microPascals (.00002 Pascals) and the level being measured.
  • Page 72 Appendix B Glossary of Terms Free field setting (microphone) Measurements made in an area without sound reflections, diffractions and absorptions caused by nearby objects (including the operator). Sound waves are free to spread out continuously, like ripples on a pond, without reflection. When making free field measurements with a dosimeter set up for use as a sound level meter, the microphone is typically pointed directly at the sound source.
  • Page 73 Appendix B Glossary of Terms Leq (Equivalent Level) The true equivalent sound level measured over the run time. The term Leq is functionally the same as Lavg except that it is only used when the Exchange Rate is set to 3 dB and the threshold is set to none.
  • Page 74 Appendix B Glossary of Terms PEL (Permissible Exposure Level) The A-weighted sound level at which exposure for a Criterion Time, typically eight hours, accumulates a 100% noise dose. Projected Time The variable amount of time used to make a projected dose calculation from an actual dose measurement.
  • Page 75 Appendix B Glossary of Terms Threshold The threshold affects the Lavg, TWA, and Dose measurements. All sound below the threshold is considered nonexistent noise for the averaging and integrating functions. The threshold does not affect measurements in the sound level mode. OSHA uses two different thresholds. The original Occupational Noise Exposure Standard (1971) used a 90 dB threshold and called for engineering controls to reduce the noise levels if the eight-hour TWA was greater than 90 dB.
  • Page 76 Appendix B Glossary of Terms Weighting (A, C, Z, etc.) “A”, “B”, “C”, “Z” and LINEAR are the standard weighting networks available. These are frequency filters that cover the frequency range of human hearing (20 Hz to 20 kHz). “A” weighting is the most commonly used filter in both industrial noise applications (OSHA) and community noise regulations.
