properly suppressed by the automatic room EQ. At these times, overall gain adjustments are performed so that the
volume sensation itself does not change.
Data measuring method:
In the configuration as in Figure 2-8, voices before and after processing with the automatic room EQ were measured
by turning it ON and OFF via the software.
* The above validation results were obtained using YVC-1000 firmware Ver.1.05.

2) For large reverberation environments
The automatic room EQ property of cutting off a band subject to large reverberations was validated.
(Graph 2-7)
Graph 2-7 expresses the automatic room EQ property differentials when the automatic room EQ is operated in
rooms with virtually no reverberations (100 ms reverberation time), and when it is operated in rooms with many
reverberations (1100 ms or greater reverberation time). In this manner the YVC-1000 automatic room EQ
automatically evaluates the reverberation effects in rooms, and in response to them it attenuates the great
frequency bands of the reverberation effects to eliminate “muffled and muttered voices,” to actualize clear voice
sound pickups.
