Graphic sound level meter screen
This screen displays the following information:
•
The numerical value of the function defined, as F1 on the sound level meter mode
preferential screen (2.3.1).
•
The time history of this function (60 values).
By pressing
you access the statistical sound level meter mode.
Statistical sound level meter screen

of each consecutive T
duration interval (integration time). Percentiles are calculated from the sound pressure
level with time averaging ‘F’ and frequency weighting A in 0.1 dB classes.
By pressing
you access the advanced sound level meter mode.
To display the total percentiles (for the entire measurement) you have to stop the
measurement as they can only be calculated after the measurement is complete (see
sections 2.3.4 and 2.3.5)
Advanced sound level meter screen
In the advanced sound level meter screen some special acoustic functions are shown. Its
measurement gives complementary information to the one given in the numeric sound level
meter screen.
In this group of functions, one can find impulsivity detectors, indicators of low spectral
content and several functions from international, national or local standards.
The SC310, in its basic version (without modulus), has the following functions on this screen:
