In complement of the five measurement modes in the device,
DB300
proposes optional modes and processing software which enlarge
the user investigation domain.
F-13: Analyzer – integrating averaging with storage sound level meter function – filters by third octave bands from 12,5 Hz to
20 kHz (class 1) or from 25 Hz to 10 kHz (class 2)
The spectral analysis by filters of
third octave
bands enables a specific description of sound ambiance in industry, building and
environment, in matter of marked tonalities.
The operating principle of this mode is the same as the one integrating the filters by octave bands. For any use which is not detailed
below, please see the following mode:
Analyzer – integrating averaging with storage sound level meter function – filters by
