If you think the threshold of pain is the sound intensity level of LI = 120 dB than you can convert that value to sound intensity I.
Reference sound intensity Io = 10^−12 W/m² (Threshold of hearing).
Reference sound intensity level LIo = 0 dB-SIL (Threshold of hearing level).
Get sound intensity I when entering sound intensity level LI = 120 dB.
Sound intensity I = Io×10^(LI/10) W/m² = 10^−12×10^(120/10) W/m² = 1 W/m².

How much db noise produce pain to human?
Anything over 85db can cause hearing loss, and small firearms produce about 120db. Whether or not these produce pain depends on the individuals sensitivity. to sound. A rocket on launch pad produces around 180db on launch which causes irreversible damage. It is also important to note how the intensity of sound changes with its db level. Sound at 190db is 10 times more intense then 180db So a sound at 200db would be equal to 20 rocket launches.
Differentiate threshold of hearing and threshold of pain?
The threshold of hearing is the minimum sound level that a person can hear when no other sounds are present. This point will vary from person to person, but is typically reported as the RMS sound pressure of 20 micropascals or 2×10−4 dynes per square centimeter - that equals 0 dBSPL. The threshold of pain is the point at which pain begins to be felt. It is an entirely subjective phenomenon. The pressure at which sound begins to feel painful is the pain threshold pressure. It starts with 20 pascals or 120 dBSPL to be painful.
What is the difference between loudness and intensity?
Sound intensity or acoustic intensity can be calculated from the objective measurement of the sound pressure. The loudness is a psycho-acoustic subjective feeling, which is difficult to measure.
Human ear is sensite to sound intensity ranging from db?
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".
What is a pain threshold?
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.
The degree of loudness or intensity?
The degree of loudness or intensity of sound is measured in decibels (dB). It indicates how loud or soft a sound is perceived by the human ear, with higher decibel levels corresponding to louder sounds. The threshold for pain from sound is around 120-130 dB.
What is the maximum intensity of sound which is harmless to man?
The maximum intensity of sound that is considered harmless to humans is around 85 decibels for prolonged exposure, such as in a normal conversation. Beyond this level, prolonged exposure can lead to hearing damage or other health effects. Shorter durations of exposure to higher levels may also cause harm.
What is the dB rating for pain threshold?
If you mean the sound pressure level that causes pain, it is about 120 dB SPL.
What intensity of sound is painful to human ears?
Sound intensities above 120 decibels are usually considered painful to human ears. Prolonged exposure to sounds at this intensity can cause hearing damage. Common sources of sound at this intensity include concerts, explosions, and gunfire.
At what intensity does noise start to become painful?
AnswerThat depends on the sort of sound and the listener.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. Our ear drums are moved only by sound pressure and not by acoustic intensity.Different values for the threshold of pain are found in the literature:sound pressure level in dB SPL and sound pressure in Pa.120 dBSPL = 20 Pa130 dBSPL = 63 Pa134 dBSPL = 100 Pa137.5 dBSPL = 150 Pa140 dBSPL = 200 PaThe volume refers to psycho-acoustic loudness. It is a common term for the amplitude of sound, the sound pressure or the sound pressure level.Prolonged exposure to sound pressure levels in excess of the threshold of pain can cause physical damage, potentially leading to hearing impairment.
What is the pain threshold for human hearing?
Human hearing is typically between 20 Hz an 20,000 Hz
What Sound Is 180.6 Db Loud?
A sound with a volume of 180.6 dB would be extremely loud, likely causing immediate physical pain and potential hearing damage. This level of sound intensity is far beyond what the human ear can comfortably tolerate and would be equivalent to the sound of a rocket taking off at close range.
