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

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
What depend on the frequency on the sound waves?
Pitch
What determines the highness or lowness of a sound?
The frequency of a sound wave determines the pitch of the sound. Higher frequency waves produce higher-pitched sounds, while lower frequency waves produce lower-pitched sounds. The pitch is perceived by the human ear based on how rapidly the sound wave vibrates.
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.
The pitch you hear is related to the of a sound wave?
The pitch of a sound wave is directly related to its frequency. Higher frequency waves produce higher pitch sounds, while lower frequency waves produce lower pitch sounds. Pitch is essentially how high or low we perceive a sound to be.
The higher the frequency of a sound wave the?
The higher the frequency of a sound wave, the higher the pitch of the sound perceived by the human ear.
Which animal can produce the highest frequency sound?
Blue whale.
The frequency of its sound wave determines its what?
The sensation of a frequencies is commonly referred to as the pitch of a sound. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave.
The length of the sound wave determines?
The pitch of the sound. Sound waves with shorter wavelengths have higher frequency and produce higher-pitched sounds, while longer wavelengths have lower frequency and produce lower-pitched sounds.
How does frequency determine sound?
Frequency refers to the number of vibrations per second in a sound wave. Higher frequencies produce higher-pitched sounds, while lower frequencies produce lower-pitched sounds. The pitch we perceive is directly related to the frequency of the sound wave.
An increase in a sound's pitch corresponds to an increase in what other property?
An increase in a sound's pitch corresponds to an increase in its frequency. Pitch is determined by the frequency of sound waves, where higher frequencies produce higher pitch sounds and lower frequencies produce lower pitch sounds.
How does the frequency and wave length of the sound waves be produce and changed with a guitar?
because it makes sound
