14.3 Displaying the Results

The Reverberation Time Measurement screen includes three tabs at the bottom: Overview,

Spectrum and Decay. The tabs allow you to choose different ways of displaying the

measurement results:

• Overview: Shows the measurement positions in a table – one position per row. Use this to

get an overview of your measurements, to include/exclude positions from the spatial

average of all positions in the room, and to manage annotations/signal recordings at the

positions

• Spectrum: Shows the reverberation spectra graphically, or as a table, for one position, or for

the room average. Alternatively, it can show the instantaneous sound pressure level while

measuring

• Decay: Shows the reverberation decay at a single frequency, for one position, or for the

room average

14.3.1 Overview

The Overview tab shows the measurement positions in a table – one position per row.

Status Field

The Status Field consists of three lines (see Fig.14.6) – the first two lines of information are

common to the status lines in the Sound Level Meter and Frequency Analyzer (see Chapter 4).

Note: The first line of the Status Field might also contain a smiley, indicating the quality of the

room (the spatial average of all positions). See the description of smileys in the following

paragraph and section 14.5.
