In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. … Sound waves below 20 Hz are known as infrasound.

Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed.

  • Wavelength. ..
  • Amplitude. …
  • Time-Period. …
  • Frequency. …
  • Velocity of Wave (Speed of Wave)

The simplest and most obvious use of sound energy is for hearing. Humans can hear frequencies between about 20 Hz and 20,000 Hz. … Another way that we use sound waves to learn about our surroundings is SONAR (short for Sound Navigation And Ranging), which is used to map objects on the ocean floor.Jan 24, 2013.
