The threshold of hearing is 0 dB. The threshold of pain = 137.5 dB.
We can hear from 0 dB, that is the threshold of hearing up to 130 dB that is the threshold of pain.
You can start to hear at the threshold of hearing at 0 dB and end up at the threshold of pain at 137.5 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".
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
Reference sound intensity Io = 10^−12 W/m² (Threshold of human hearing). Reference sound intensity level LIo = 0 dB-SIL (Threshold of human hearing intensity level). The sound intensity I is measured in watts per meter squared. The sound intensity LI level is measured in decibels (dB).
If you mean the sound pressure level that causes pain, it is about 120 dB SPL.
The sensation level is measured in decibels. It is frequency specific and starts at 0 dB SL (sensation level) where 0 dB SL is the softest the patient can here a specific frequency. This means that the SL will be different for different people. Everyone's SL will start at 0 but my SL at 1000 Hz may be at 23 db IL and another's may be at 54 db IL.Put more simply, dB SL is the difference between a person's threshold of hearing and the presentation level of a stimulus. If a person's speech reception threshold (SRT) is 10 dB on an audiometer (dB HL) and you present a speech stimulus to them at 50 dB HL on the audiometer, their sensation level would be derived thus: 50 dB (presentation level) minus 10 dB (threshold), which equals a sensation level of 40 dB SL. This is also the procedure for a frequency-specific stimulus (e.g. pure tones): subtract the audiometric threshold (dB HL) from the supra-threshold presentation level (dB HL) and the difference is the sensation level (dB SL).
It varies from person to person. However - an accepted 'normal' hearing range is around 20 Hz to 20,000 Hz. The same goes for pain threshold - anything over 120 dB would certainly be uncomfortable for most people.
That depends on the listening person. 120 dB will bring you pain.
Reference sound intensity Io = 10^−12 W/m² (Threshold of human hearing). Reference sound intensity level LIo = 0 dB-SIL (Threshold of human hearing intensity level). Sound intensity is a sound energy quantity. Our eardrums are moved by sound pressure variations. That is a sound field quantity. Reference sound pressure po = 20 µPa = 2×10^−5 Pa (Threshold of human hearing). Reference sound pressure level Lpo = 0 dB-SPL (Threshold of human sound pressure hearing level).
The minimum of sound intensity can be theoretically as low as zero decibels. But you seem to mean what the human threshold of hearing is. That reference sound intensity is 10^−12 W/m² equal to 0 dB sound intensity level. Our eardrums are moved by the sound pressure. The reference sound pressure at the human threshold of hearing is po = 20 µPa equal to 0 dB sound pressure level (SPL).
