What is the maximum peak sound pressure level exposure to impulsive noise for workers?

The maximum peak sound pressure level exposure to impulsive noise for workers is 140 decibels (dB). This limit is established by regulatory standards, including those from the Occupational Safety and Health Administration (OSHA), to protect workers from the harmful effects of loud noise in the workplace. Exposure to impulsive noise above this level can lead to hearing loss or other auditory issues, making adherence to this benchmark critical in construction and other noisy environments.

Higher sound pressure levels, such as 150 dB or 160 dB, represent thresholds that exceed safe exposure limits and could significantly increase the risk of immediate and long-term hearing damage. Similarly, a limit of 130 dB is also considered below the acceptable maximum for impulsive noise and does not reflect current guidelines that prioritize worker safety in environments where occasional loud noises may occur. Thus, 140 dB is affirmed as the appropriate maximum, balancing the need for worker safety with the realities of occupational noise exposure.
