Frequency Weighting Z (zero): Frequency Weighting equal to 0 dB from 10 Hz to 20 kHz
It also measures the following functions:
•
The total percentile levels corresponding to 1, 5, 10, 50, 90, 95 and 99 % of the entire
measurement and the partial levels of each T interval of the sound pressure level with time
averaging ‘F’ and frequency weighting A.
The
SC310
also displays the following acoustic functions:
•
The subtraction of the equivalent continuous sound pressure level with time averaging ‘I’
and the equivalent continuous sound pressure level, corresponding to the measurement
time and to the programmable integration time T. These two functions measured with
frequency weighting A, C and Z
•
The subtraction of the equivalent continuous sound pressure level with frequency
weighting C and the equivalent continuous sound pressure level with frequency weighting
A, corresponding to the measurement time and to a programmable integration time T.
As an octave band spectrum analyser (1/1), it measures simultaneously and in all the
dynamic range (single scale) the following functions:
•
The equivalent continuous sound pressure level with programmable consecutive
integration time T and without frequency weighting for each octave band centred on
frequencies of 31.5, 63, 125, 250, 500, 1000, 2000, 4000, 8000 and 16000 Hz.
•
The equivalent continuous sound pressure level with programmable consecutive
integration time of 125 ms and without frequency weighting for each octave band centred
on frequencies of 31.5, 63, 125, 250, 500, 1000, 2000, 4000, 8000 and 16000 Hz
*
•
The equivalent continuous sound pressure level of the integration time 125 ms and with
frequency weighting A, C and Z
*
•
The maximum of the peak sound pressure level corresponding to the 125 ms integration
interval with frequency weighting A, C and Z.
•
The equivalent continuous sound pressure level of the T integration interval with frequency
weighting A, C and Z.
•
The maximum of the peak sound pressure level for the T integration interval with
frequency weighting A, C and Z.
•
The partial percentile levels corresponding to 1, 5, 10, 50, 90, 95 and 99 % of the
equivalent continuous sound pressure level corresponding to the integration time T
measured for each octave band.
•
The overall percentile levels corresponding to 1, 5, 10, 50, 90, 95 and 99 % of the total
equivalent continuous sound pressure level measured with frequency weighting A and
corresponding to the integration time T.
The
SC310
has a background noise evaluation screen where the following acoustic functions
are shown:
•
The value of the NC (Noise Criterion) curve corresponding to the measured spectrum
•
The value of the NC curve that has not been exceeded in each octave band
As a one third octave band spectrum analyser (1/3), it measures simultaneously and in all
the dynamic range (single scale) the following functions:
