At what level does sound begin to be perceived as painful?

Sound begins to be perceived as painful around 120 dB SPL (sound pressure level), which marks the threshold where discomfort from sound typically begins for most individuals. However, levels above this, particularly at around 130 dB SPL and above, can result in actual pain.

While the answer selected is 140 dB SPL, which does correlate with extreme sound levels that can undoubtedly be painful, this value is on the higher end of the range. It is generally noted in audiology that while sounds around 120 dB SPL may lead to discomfort, 130 dB SPL is the level at which sounds can begin to feel quite painful for many people.

Understanding how sound intensity relates to discomfort and pain is crucial for those studying hearing disorders, as excessive exposure to loud sounds can lead to long-term auditory damage and other health risks.
