オーディオ関係者にはことに理解もされていないのは事実です。
人および動物の音聴における Phase deafness, このスレに引用を残させていただきます。
1. “Science and Music", Sir James Jeans, 1937 (Dover 1968), p86).
The timbre depends only on the relative energies of the various harmonics and not on
their phase-differences. Differences of phase produce no effect on the ear. This is
known as as Ohm's law, having been discovered by G.S. Ohm (1787-1854),
the discoverer of the still better known electrical law.
2. "The theory of Sound", J.W.S. Rayleigh, 1896, Section 386).
According to the literal statement of Ohm's law, the ear is capable of hearing as separate
tones all the simple vibrations into which the sequence of pressures may be analysed by
Fourier's theorem, provided that the pitch of these components lies between certain limits.
Components whose pitch lies outside the limits would be ignored. Moreover, within the
limits of audibility the relative phases of the various components would be a matter of indifference.
