Page 10: Chapter 1: Introduction
CHAPTER Dosimetry 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 11: Noise Dosimeter
Overview Noise dosimeter 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 12: Range Of Sound
Overview Range of sound 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. -
Page 13: Applications Of The Edge
Overview Applications of the Edge 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 61: Appendix B: Glossary Of Terms
APPENDIX Appendix 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 62 Appendix B The C-A measurement is an L that enhances the low- frequency components of the sound signal. It is the result of subtracting an A-weighted L from a simultaneously collected C-weighted L and is sometimes used as the NRR (noise reduction rating) factor to determine if hearing protection devices are adequate for usage in the field.
- Page 63 Appendix B Crest Factor Crest Factor is the ratio of the instantaneous peak value of a wave to its RMS value. This is a performance specification of a meter’s ability to process signals that have peaks that are substantially higher than their RMS averages. Criterion Level (CL) Criterion level is the average SPL that will result in a 100% dose over the Criterion time, usually 8 hours.
- Page 64 Appendix B Exchange Rate (ER – also known as the Doubling Rate) Exchange rate refers to how the sound energy is averaged over time. (Also, referred to as Doubling Rate.) Using the decibel scale, every time the sound energy doubles, the measured level increases by 3dB. This is the 3dB exchange rate that most of the world uses.
-
Page 65: Measurement Range
Appendix B Logging (Also called Data Logging.) Certain measurements, such as average level (Lavg) and maximum level (max), can be recorded by the dosimeter at regular intervals. For example: A dosimeter is set to log Lavg and max at one minute logging intervals. If the dosimeter runs for one hour, then it would log 60 Lavg results and 60 max levels. -
Page 66: Response Time
Appendix B Response Time The response determines how quickly the unit responds to fluctuating noise. Fast has a time constant of 125 milliseconds. Slow has a time constant of 1 second. Example: Typically, noise is not constant. If you were to try to read the sound level without a response time, the readings would fluctuate so much that determining the actual level would be extremely difficult. - Page 67 Appendix B then measure for the entire 6.5 hours. TWA is the correct level to report to OSHA. It does not have to be modified. 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 (20Hz to 20 kHz).
