Sound measurements

distance travelled during a unit of time by a sound wave propagating through an elastic medium

instantaneous product of sound pressure and particle velocity

measurement of a signal at discrete time intervals

local pressure deviation from the ambient atmospheric pressure, caused by a sound wave

quotient of average sound pressure at a surface and sound volume flow rate through that surface

individual whale which has been detected calling at 52 Hz, far above the normal whale vocal range

device for acoustic measurements

In electronics, crosstalk (XT) is a phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel. Crosstalk is usually caused by undesired capacitive, inductive, or conductive coupling from one circuit or channel to another.

periodic vibration whose frequency is audible to the average human

surface integral over the sound intensity

volume integral of the sound energy density

audio exceeding CD capability

unit of sound absorption

the number of bits of information recorded for each sample

time derivative of the sound particle displacement

measure of the energy loss of sound propagation in media; phenomenon when hearing protectors help reduce acoustic flux from flowing into the ears, is measured in decibels (dBs)

cartographical representation of the sound intensity

instantaneous displacement of a particle from its equilibrium position in a medium as it transmits a sound wave

time-averaged sound energy in a volume

sound level meter for measuring noise exposure over a period of time
