OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at https://www.osha.gov.

Mr. Robert J. Wurm
Vice President and General Manager
Quest Electronics
Post Office Box 128

Conomowoc, Wisconsin 53066

Dear Mr. Wurm:

This is in response to your letter of August 3, inquiring about the acceptability of Quest Electronics' Model BA-201 Bio Acoustic Simulator for peforming the daily check of the functional operation of an audiometer, required at 29 CFR 1910.95(h)(5)(i) of the Occupational Noise Exposure standard.

The Occupational Safety and Health Administration (OSHA) does not approve products, but we can state in general that a product that has the properties described in your Model BA-201 sales literature (carrying the identification numbers 98- 160/11-83) would meet the intent of the standard, and thus can be used to make the daily check.

Thank you for your inquiry. If we can serve you again in the future, we shall be glad to do so.


John B. Miles, Jr.
Directorate of Field Operations
