15 ACOUSTICAL PARAMETERS
15.1 INTRODUCTION
With the Acoustical Parameters control panel it is possible to evaluate the acoustical
behavior of a room and carry out sophisticated post processing of a measured
impulse response to calculate the acoustical parameters as defined by the ISO
3382 standard. These quantities describe the behavior of auditoria, concert halls
and are applicable to any room intended for speech or music reproduction.
15.2 THE ACOUSTICAL PARAMETERS CONTROL PANEL
Fig. 15.1 The Acoustical Parameters control panel
In Fig. 9.1 you can see the Acoustical Parameters control panel; this figure shows
an octave filtered impulse response (at 1kHz) presented both as reverberant decay
and ETC; then all the calculated parameters are listed in tabular form.
The source of any acoustical parameters calculation is a measured Impulse
Response; CLIO gives you this possibility by means of the MLS&LogChirp menu;
please refer to chapter 10 where it is described how to measure the impulse
response of a room using MLS or LogChirps.
For a detailed description of the graphical display (common also to other
measurement control panels) and its capabilities please refer to Chapter 6. For a
description of the available shortcuts please refer to section 5.5.2.
