What is the threshold of pain for humans in dBSPL?

The threshold of pain for humans is typically around 140 dBSPL. This measurement indicates the sound pressure level at which sounds become unbearably loud and can cause physical discomfort or pain to an individual. At this level, the intensity of sound signals exceeds what the auditory system can comfortably tolerate, leading to potential hearing damage or other physical reactions. This threshold is considerably higher than the levels typically associated with normal conversation (around 60 dBSPL) or even loud music (which can reach around 100-110 dBSPL). Understanding the threshold of pain is crucial in fields such as audiology and acoustics, as it helps inform practices and regulations aimed at protecting individuals from exposure to harmful sound levels.
