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
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.
Pitch
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 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.
a high pitched sound
Higher frequencies produce the perception of higher pitch sound. A woman's voice generally contains sounds with higher frequencies than a man's voice contains. An infant's voice contains higher frequencies than an adult's voice does.
The Mosquito or Mosquito alarm is an electronic device, used to deter loitering by young people, which emits a sound with a very high frequency. :)
The pitch is determined by how high the sound is.
Anything you hit makes a vibration. Vibration=Sound. I guess it depends how hard you hit the object (in this case metal) you will be able to hear the sound. But yes, they do make a high pitched sound when you hit them (some so high pitched you will never be able to hear them).
