Acoustics

phase

Science; Acoustics

Phase describes where in its cycle a periodic waveform is at any given time. the phase of a wave is given in radians, degrees, or fractions of a wavelength.

beat

Science; Acoustics

Phenomenon that results from the superposition of two or more waves of the same kind but of different frequencies.

angular

Science; Acoustics

Physical properties or quantities measured with reference to an angle, especially those associated with rotation

Point, line or surface in a standing wave where some specified characteristic of the wave field has essentially zero amplitude. In practice, this amplitude is generally not zero but simply a minimum. ...

particle

Science; Acoustics

Portion of a medium whose volume has dimensions which are small compared to the wavelength of the sound.

dBm, dB(mW)

Science; Acoustics

Power relative to 1 miliwatt. No reference impedance is assumed, though 600 ohms is common in audio equipment.

noise mapping

Science; Acoustics

For noise mapping the Lden or LDEN also known as the day-evening-night level is used. Noise maps published on the internet are widely used in Europe and are becoming used in the UK.
