a.
Calculate the 8-hour time-weighted average (TWA) noise exposure for each of the
three workers.
b.
Summarize which (one) of the exposures exceeds OSHA’s permissible exposure
limit (PEL) and/or action level for noise.
c.
Discuss what factors about the noise monitoring may have affected the accuracy
of the noise measurements.
Show
your work for all mathematical calculations. Please refer to Appendix A to 29
CFR 1910.95 for assistance on how-to solve this problem. Your response must be
a minimum of 200 words in length.
Question
2
Summarize
the characteristics and abilities of sound level meters (SLMs) and noise
dosimeters and how they can be used to evaluate noise exposures at a facility.
Your
response must be a minimum of 200 words in length.
Question
3
Define
the following terms associated with occupational noise:
a.
Wavelength
b.
Frequency
c.
Sound Pressure
d.
Decibel
e.
Octave Band
Your
response must be a minimum of 200 words.
Question
4
You
have been tasked with establishing and implementing an effective hearing
conservation program for a metal stamping facility. Noise monitoring shows that
employees working in the press areas of the facility are exposed to 8-hour TWA
noise exposures between 85.0 dBA and 89.0 dBA. Based on the requirements of 29
CFR 1910.95, summarize the requirements for an effective hearing conservation
program and discuss steps to make the program as effective as possible. Please
refer to 29 CFR 1910.95(b)(2) for the formula.
