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 is the relationship between sound waves frequency and the pitch of a sound?
The frequency of a sound wave is directly related to the pitch of a sound. Higher frequency sound waves produce higher pitch sounds, while lower frequency sound waves produce lower pitch sounds.
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 is the highest frequency sound that can be heard by the human ear?
The highest frequency sound that can be heard by the human ear is around 20,000 Hz.
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.
How does the frequency of sound waves impact their behavior and characteristics?
The frequency of sound waves affects their pitch and wavelength. Higher frequencies result in higher pitches and shorter wavelengths, while lower frequencies produce lower pitches and longer wavelengths. Additionally, the frequency of sound waves can impact how they are perceived by the human ear and can influence the overall quality of the sound.
The higher the frequency of a sound wave the?
the frequency of a sound wave is higher if its wavelength is shorter
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.
