At what decibel level does the threshold of pain occur?

The threshold of pain in terms of sound intensity typically occurs around 120 decibels for most individuals. This level is where sounds can start to cause discomfort and potential auditory damage. Sounds at or above this level can lead to pain due to overstimulation of the auditory system, particularly affecting the inner ear structures and leading to a sensation of pain rather than simple hearing discomfort.

While the other levels mentioned may be loud, they do not align with the commonly accepted threshold of pain, which is generally recognized to be around 120 dB. Sounds that exceed this decibel level can certainly be excruciating, but it's important to note that the consensus for the threshold of pain is predominantly at 120 dB. Thus, the chosen answer reflects the scientifically established point at which sound becomes painfully loud for most people, underlining the seriousness of prolonged exposure to such sound levels.
