Audiometric testing monitors an employee's hearing over time. It also provides an opportunity for employers to educate employees about their hearing and the need to protect it.
The baseline audiogram is the reference audiogram against which future audiograms are compared. Employers must provide baseline audiograms within 6 months of an employee's first exposure at or above an 8-hour TWA of 85 dB. An exception is allowed when the employer uses a mobile test van for audiograms. In these instances, baseline audiograms must be completed within 1 year after an employee's first exposure to workplace noise at or above a TWA of 85 dB.Annual Audiograms:
Employers must provide annual audiograms within 1 year of the baseline audiogram. It is important to test worker's hearing annually to identify deterioration in their hearing ability as early as possible. This enables employers to initiate protective follow-up measures before hearing loss progresses. Employers must compare annual audiograms to baseline audiograms to determine whether the audiogram is valid and whether the employee has lost hearing ability or experienced a standard threshold shift (STS). An STS is an average shift in either ear of 10 dB or more at 2,000, 3,000 and 4,000 hertz.
For maximum protection (of both your employee and your company) and to test specifically for the ability to hear warning signals, an audiogram should be performed:
Hearing tests can be performed at any 3 of our Buffalo locations and also inside our mobile services facility. All hearing instruments are carefully calibrated on an annual basis based on specific manufacturer's instructions.
