Hearing Conservation Program
Proposal
Dear Mr. Smith, Thank you for your inquiry about a hearing conservation program for your company. I’ve provided an outline of a hearing conservation program with OSHA guidelines and costs for you to consider.
To clarify some of your questions, the abbreviation of dB stands for decibels, which is how acoustic power is measured. Since the human ear can’t hear all the sounds that may be measured by a sound level meter or dosimeter, we will often add weighting, called A-weighting, to relate the results more accurately to the human ear. When dBs are averaged among the hours of an employee’s 8-hour workday, we call it the 8-hour time-weighted average. We can also calculate a time-weighted average using dBA to be more accurate with our findings.
Please read through the provided materials and OSHA 1910.95 document and contact me with any remaining questions. I look forward to working with you & providing a safe sound environment for your employees!
Sincerely,
OSHA 1910.95(d)
A workplace environment must be monitored if employees are exposure to a level of 85 dBA or greater. To determine if the employees in the packing and shipping room are exposed to 85 dBA or greater the first step would be to measure the noise the employees are exposure to throughout their workday. The average of noise is then calculated in a time-weighted average to get the overall level of noise that the employees are exposed to over an 8-hour day. Noise sampling would need to be done in the overall area of the room to determine how much noise certain machinery is making using a sound level meter and sampling would need to be done on each employee’s work spot within the factory by having the employees wear a dosimeter for a typical 8-hour work day. These measurements will allow me to monitor the noise levels within the factory and calculate and estimate of the time-weighted average to determine if the levels that OSHA measured are accurate. I will average both the area monitoring levels and personal monitoring to get a combined average of noise the employees are exposed to over an 8-hour workday. If the time weighted average exceeds 85 dBA, we will need to implement a hearing conservation program for the employees who work within the packing and shipping room. According to the OSHA document 1910.95(e) employers must notify their employees if they are exposed to an 8-hour time weighted average of 85 dB or higher. Monitoring of noise should also be repeated if a modification in the machinery and/or controls is made that might cause a change in the sound levels within the factory. Engineering Controls Engineering controls need to be implemented for noise levels exceeding 90dBA. Since OSHA measured the shipping and packing room to be 93dBA, it is important we discuss this topic. Engineering controls consist of anything that can be added or changed within the shipping and packing room to reduce noise levels omitted from the machines. For this job, I have contacted an acoustical engineer who agreed to survey the room and make recommendations to help reduce sound levels. He will talk to you about acoustic absorption materials, such as carpeting and curtains and transmission loss, materials that will block or resist sounds. We hope to eliminate approximately about 5 dB with engineering controls. Administrative Controls Administrative controls will provide information regarding your question about switching work shifts between the packing and shipping room to the baseball card room. Although this will reduce the noise levels for the employee’s within the packing and shipping room, you would be exposing the employee’s …show more content…
This baseline audiogram will provide us with the starting threshold levels of the employees and allow us to see if their hearing declines due to noise exposure within the factory. It will also allow us to see if the hearing conservation program is working. The one exception to this rule is that there is a 12-month period if a mobile van is used for the audiometric testing. If you chose to use my hearing conservation program, Audiometric testing will not be conducted in a mobile test van, so the 6-month period will need to
