What is the threshold for hearing loss level in OSHA standard?

Explanation:
OSHA uses a specific trigger to flag occupational hearing loss: a standard threshold shift. This is defined as a change in hearing threshold of 25 dB or more in the 2,000, 3,000, and 4,000 Hz range in the same ear, compared to the employee’s baseline audiogram. When this 25 dB shift is reached, it signals that action is needed—such as retraining, additional monitoring, and enforcing the hearing conservation program. The other numbers represent amounts of loss that aren’t the OSHA trigger for a standard threshold shift.
