A 10-dB confirmed threshold shift from baseline in pure-tone average at 2000, 3000, and 4000 Hz (OSHA standard threshold shift or STS), while not necessarily resulting in significant impairment, is an important early indicator of permanent hearing loss. Hearing loss is typically a gradual process, and by the time its effects are noticeable, it is often too late to do anything about it.
