123 Street Drive, Somewhere, ST 01234 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…

However it could be that it smell as that's what ‘musty’ means. ‘, silence,’ has commas either side of it making it create pace. Susan Hill uses ‘seething’ making it seem like the air is crowding Arthur. Susan has used a list to create pace also. Tension is sustained in this part of the chapter as it seems that Arthur is walking into a thick foggy…
