What is Occupational Noise and Why DOES IT MATTER?
Noise is one of the most prevalent occupational health problems that heavy workforces face today. Exposure to high levels of noise can cause hearing loss and may cause other harmful health effects. These harmful effects may be temporary or permanent. In addition, loud noises can generate physical and psychological stress, reduce productivity, and increase the chances of workplace accidents.

What is Audiometric Testing?
How Often Should Testing Be Done?
Employers must provide annual audiograms within 1 year of the baseline. It is important to test workers’ 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.
