130 dB is an SPL commonly considered to be the threshold of pain. Between 120 and 140.

If you mean the sound pressure level that causes pain, it is about 120 dB SPL.
It depends on how loud it is. In hearing, the threshold of pain is the sound pressure or sound pressure level beyond which sound becomes unbearable for a human listener. This threshold varies only slightly with frequency. Different values for the threshold of pain are found in the literature: Here are some sound pressure levels SPL in dB and the sound pressure in pascals of the sensed possible threshold of pain: SPL 120 dB = 20 Pa SPL 130 dB = 63 Pa SPL 134 dB =100 Pa SPL 137.5 dB =150 Pa SPL 140 dB =200 Pa
The usual soundlevel can be between 0 dB SPL = 20 µPa (threshold of hearing) up to 130 dB SPL (threshold of pain). An average sound level could be at 85 dB SPL. Scroll down to related links and look at "Average sound pressure levels".
The human is is not sensitive to sound intensity (energy), but the human ear is sensitive to sound pressure or to sound pressure level (SPL). It is ranging from 20 micropascals to 150 pascals, that is a SPL of 0 dB (threshold of hearing) to 137.5 dB (threshold of pain). Scroll down to related links and look at "Table of Sound Levels and corresponding Sound Pressure".
The threshold of hearing is 0 dB. The threshold of pain = 137.5 dB.
it means your body sends more pain then needed towards places that have been punched, kicked ect then someone with regular pain threshold. as pain is just a message from your body saying to stop but if you have a low pain threshold your body sends too much pain.
pain threshold
Well if you have a 'high pain threshold' you seem to feel a lot more pain then you do if you have a 'low pain treshol'.
It's the sound pressure deviation we measure as sound pressure level (SPL). The threshold of pain is known in acoustics as the lowest strength of a stimulus that is perceived by the ear as painful. Because of the different sensitivity of the hearing of people it cannot be given an accurate value. You can find the following rounded values for threshold of pain in various audio articles and books: 140 dB SPL equivalent to 200 Pa 137.5 dB SPL equivalent to 150 Pa 134 dB SPL equivalent to 100 Pa 130 dBSPL equivalent to 63 Pa 120 dBSPL equivalent to 20 Pa Sound pressure levels more than 140 dB at your ears will burst your eardrums. Don't forget that the distance from your ears to the sound source is very important. So keep off.
Having a high pain threshold means you can take more pain than most people without it becoming unbearable
A pain threshold is the point at which a person starts to feel discomfort or pain from a stimulus. It is the level of intensity at which a person perceives a sensation as painful. Different individuals have different pain thresholds.
I just read that number yesterday ... and on this website, in fact. It's considered to be 2 x 10-5 micropascals.
