Acoustics
monopole sound source
Science; Acoustics
Source that radiates sound equally in all directions in a free field.
simple sound source
Science; Acoustics
Source that radiates sound equally in all directions in a free field.
narrow band spectra
Science; Acoustics
Spectra that have been measured using a narrow frequency bandwidth.
total sound energy density
Science; Acoustics
Sum of instantaneous potential and kinetic energy densities.
spatial averaging
Science; Acoustics
Taking measurements at various positions and averaging the results. Mandatory in sound insulation measurements and recommended anywhere multiple reflections are present. Other averaging methods
divergence loss
Science; Acoustics
That part of the transmission loss due to the divergence, i.e. spreading, of sound waves in accordance with the configuration of the system, also known as spreading loss. Note: divergence loss ...
community noise equivalent level (CNEL)
Science; Acoustics
The 24 hour average noise level of all hourly leq measurements with a 10 dB penalty added to the levels between 2200 and 0700 hours and a 5 dB penalty added to the levels between 1900 and 2200 hours ...
