Hazardous impulse noise levels are categorized as what dBP or higher?

Hazardous impulse noise levels are categorized at 140 dBP (decibels with reference to sound pressure) or higher based on established guidelines and research on noise exposure. This level of dBP indicates a significant loudness that can cause immediate harm to the auditory system, potentially leading to permanent hearing loss or trauma to the ear structures. Impulse noise is characterized by a sudden burst of sound, such as that from gunshots or explosions, which can be particularly damaging even if the exposure duration is very short. Recognizing levels at or above 140 dBP is crucial for protecting individuals in environments where such noise levels are commonplace. This information aligns with occupational safety standards that recommend hearing protection when exposed to sounds at these hazardous levels.
