OSHA’s Noise standard requires only that audiometric testing be made available to all employees whose exposures equal or exceed an 8-hour time-weighted average of 85 dBA. If the employee has no hearing loss and no medical problems, then no notification letter is required. On the other hand, the standard does not prohibit an employer from having a company rule that employees submit to audiometric testing.
If the employee refuses to see a physician, employers may use whatever documentation they prefer to document that they have offered the referral.
