3.2 Superiority of YVC-1000
With commercial conventional systems since it is difficult to distinguish noises and low voices, it is hard to raise the
volume of low voices. In regard to that, since YVC-1000 has raised the accuracy of voice determinations via HVAD,
sounds can be firmly raised without low voices and noises being determined.
(Figure 2-4)
< Comparisons with commercial conventional systems and validations >
Validation results:
(Table 2-2)
Table 2-2 lists the results of the comparative measuring of pickup sound levels in individual conditions (sections). In
this table the sound pickup levels in the normal volume zone are designated as the reference (0 dB) and individual
pickup sound levels in other sections are expressed relatively. As indicated in the table, what is especially being
emphasized in actual conferences, is in the performance whereas the low voices are drawn out, which confirms that
there is superiority over the +4 dB of commercial conventional systems.
Data measuring method:
In the configurations in Figure 2-5, the sound pickup levels were measured under each of the conditions in Table 2-2
via normal microphones (without automatic gain control), and YVC-1000, via commercial conventional systems.
* The above validation results were obtained using YVC-1000 firmware Ver.1.05.
