5. TYPICAL MEASUREMENT AND ANALYSIS SET -UPS

DIRECT ANALYSIS OF SOUND
Sound analysis in 1/3 octave or octave bands can be done with the set-up of
Fig.5.1. The 1615 covers the whole audible frequency range. The 1614 is
only necessary if more than the audible range has to be analysed. The Set-up
shown is also a precision sound level meter in the linear ranges of the Filter
Set.
The addition of the Level Recorder Type 2305 allows the sound spectra to
be automatically recorded on precalibrated paper. A typical sound spectra-
warn is shown in Fig.5.2.
