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. It is clear that only lower levels are permissable, because prolonged exposure to sound pressure levels in excess of the threshold of pain can cause physical damage, potentially leading to hearing impairment. Different values for the threshold of pain are found in the literature: Sound pressure level and Sound pressure:
120 dB SPL = 20 Pa
130 dBSPL = 63 Pa
134 dBSPL = 100 Pa
137.5 dBSPL = 150 Pa
140 dBSPL = 200 Pa

What range of sounds can a human produce?
The human voice typically ranges from 85 to 255 Hz. Through technology, human's can produce any frequency sound.
How does human produce loud sounds?
By vibration of vocal chords.. High frequency of vibration/low pitch = sweet sound Low frequency of vibration/high pitch = harsh sound High amplitude = loud sound
Does the pitch of sound depend on the frequency of the sound waves that produce it?
yes, the pitch of sound does, in fact, depend on the frequency of the sound wave.
What is the frequency range for human audiable sound?
The frequency range for human audible sound is 20 Hz to 20,000 Hz.
What are the characteristic of sound produce by human?
Sound has three characteristics : 1) Loudness : Measured in decibel. 2) Pitch : It is directly proportional to the frequency of sound. 3) Quality (or Timbre) : It is the difference in the quality of sound.
How does the frequency of light compare to the frequency of sound?
-- The highest frequency of sound audible to the human ear is of the order of 20,000 Hz.-- The lowest frequency of light visible to the human eye is of the order of 375,000,000,000,000 Hz.
Which animal can produce the highest frequency sound?
Blue whale.
How does the frequency and wave length of the sound waves be produce and changed with a guitar?
because it makes sound
What is the loudspeaker used to produce high frequency sound called?
A tweeter.
What does a high frequency of vibrations produce?
Heat, light and, if in an atmosphere, sound.
What is the human perception of the frequency of sound?
I think you mean pitch.
What is pitch in relation to sound?
Pitch is often used to represent the frequency of a sound in music. It is distinguished from frequency though, because pitch involves how a human perceives that sound.
