23 Nov 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 https://fea-solutions.co.uk/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.
