Repeated exposure to what decibel level can lead to hearing loss?

Repeated exposure to noise levels above 85 decibels can lead to permanent hearing loss, especially with prolonged exposure. At this level, the risk of hearing damage significantly increases because sounds at and above 85 decibels can cause stress to the auditory system. When exposed to 90 decibels for extended periods, the potential for long-term hearing impairment becomes even more pronounced. The intensity of the sound and the duration of exposure are critical factors in determining the risk of hearing loss.

Hearing conservation programs often promote the use of hearing protection in environments where noise levels reach or exceed this threshold to help safeguard auditory health. Understanding these risks is vital for individuals working in noisy environments, as early intervention can help prevent irreversible damage to hearing.
