Audio Calculations
- Acoustic Cavity
- The acoustics of enclosed volumes are important when considering sound propagation within the volume.
- A Weighting
- This is the most generally used filter when making overall noise measurements.
- Bark
- The Bark is the standard unit corresponding to one critical band width of human hearing.
- B Weighting
- The B-weigthing curve approximately follows the 70 phon curve.
- Circular Frequency
- The frequency of a steady recurring phenomenum in radians per second.
- C Weighting
- The C-weighting curve approximately follows the 100 phon curve.
- dBA
- A sound-level meter reading with an A-weighting network simulating the human-ear response at a loudness level of 40 phons.
- dBB
- A sound-level meter reading with a B-weighting network simulating the human-ear response at a loudness level of 70 phons.
- Decibel
- The human ear responds logarithmically and it is convenient to deal in logarithmic units in audio systems.
- Quarter Wave Tube
- A resonator used most commonly on automotive air intake systems to reduce resonance.
- Sound Transmission Class
- In acoustics, a single number rating for describing sound transmission loss of a wall or partition.
- Speed of Sound
- Depends on the elastic and inertial properties of the particular medium.
