Acoustics

Acoustics is the study of mechanical waves in fluids and solids. Examples of acoustic waves are:

  • Vibration (below human hearing range)
  • Sound (in human hearing range)
  • Ultrasound (above human hearing range)

Acoustic analyses can either be used to determine how mechanical waves change through a structure (e.g. acoustic transmission loss), or how the structure is changed (deformed or stressed) by the mechanical waves. Examples of objects where acoustic analysis may be required are in the design of the following:

  • Anechoic chambers
  • Concert halls
  • Musical instruments
  • Speakers
  • Vehicle interior

In acoustics the sound pressure level (or sound power level) is expressed in decibels (dB), which defines the effective pressure relative to a reference value (usually the threshold of human hearing). Decibels (dB) is a logarithmic unit, meaning an increase of 10dB is equivalent to being 10 times the pressure level.
