LOUDNESS MEASUREMENT
– Loudness
The
Loudness
function is the extension of the
Sound Meter
function for additional calculation of the so called
“Bark spectrum”. The Bark spectrum is calculated from pre-defined 1/3-octave spectrum (25 Hz - 12.5 kHz) in
accordance with the ISO 532B standard.
The
Loudness
function doesn’t require any additional settings and the Bark spectrum is calculated every time
the user presses the
<Start>
key. Calculated 1/3-octave spectrum is not saved in a logger file.
Note: The Loudness analysis is performed in parallel to the Sound Level Meter measurements.
