  • Page 15: Chapter 1 Introduction

    C H A P T E R 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 16: 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 17: 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. 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 18: 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 36: Understanding What Data Is Stored

    Understanding what Data is Stored When you are running noise dosimetry studies, there are two types of data stored on the dosimeter which include the summary data and time history (or Logged) data. Summary Data Summary data represents values that occurred over the entire run of the study. For an average value, such as Lavg, it represents the average decibel value over the entire run time.

  • Page 37: Time History

    Time History Time history data is also referred to as “logged data” which plots measurement values at a configurable time interval. Time History data represents values that occurred over the most recent time period, which is the logging interval. For example, if the log interval is 10 seconds, then the Peak value is the highest Peak value for that 10 seconds, and the Lavg value is the average dB value for that 10 seconds.

  • Page 38: Views On The Edge

    Views on the Edge The Edge is a user-friendly and customizable dosimeter.

  • Page 89: Appendix B Glossary Of Terms

    A P P E N D I X 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 90 Example Measurements with and without the noise source of interest are 91 dB and 90 dB, respectively. For a difference of 1 dB, the background noise correction value is 7 dB. Therefore, the level for the noise source of interest without the noisy background is 84 dB. Combining Noise sources Because sound levels are measured in decibels they cannot be simply added together.
  • Page 91 Example Independent measurements for the two noise sources yielded levels of 90 dB and 91 dB. For a difference of 1 dB, the correction factor taken from the curve below is 2.5 dB. Therefore, the combined level when these two sound sources are present in the measurement area at the same time 93.5 dB.
  • Page 92 Dose Related to the Criterion Level, a dose reading of 100% is the maximum allowable exposure to accumulated noise. For OSHA, 100% dose occurs for an average sound level of 90 dB over an 8-hour period (or any equivalent exposure). By using a TWA reading rather than the average sound level, the time period is no longer explicitly needed.
  • Page 93 Hearing Conservation (HC) The Occupational Safety and Health Administration (OSHA) and Mine Safety and Health Administration (MSHA) provide regulatory standards for hearing conservation programs. In addition, the American Conference of Governmental Industrial Hygienists (ACGIH) provides industrial standards for hearing conservation programs. http://www.osha.gov/ http://www.msha.gov/ , http://www.acgih.org/home.htm.
  • Page 94 Measurement Range The decibel range within which the unit’s measurements are valid. Minimum Level (Lmin) The lowest sampled sound level during the instrument’s run time allowing for the unit’s Response Time setting (Fast or Slow). Noise Floor In a “Perfectly Quiet” room, the electrical noise produced by the microphone is approximately 35 dB on A-weighting and 45 dB on C-weighting.
  • Page 95 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 96 TWA (Time Weighted Average) The time weighted average always averages the sampled sound over an 8-hour period. TWA starts at zero and grows. The TWA is less than the Lavg for a duration of less than eight hours, exactly equal to the Lavg at eight hours, and grows higher than Lavg after eight hours. TWA represents a constant sound level lasting eight hours that would result in the equivalent sound energy as the noise that was sampled.
  • Page 97 Upper Limit (UL) A type of measurement parameter setting in which the user selects a certain decibel level. The dosimeter will then record the amount of time that the sound level was at or greater than the preset level. This time is then recorded as “UL Time” Windscreen A windscreen is a covering for the microphone that reduces disturbances caused by wind and direct contact with other surfaces.
