mixed by the mixing rod & 18+, amplified by the amplifier 44+, and headphone amplification /
reverberation-biased polarization added to each side. & #F I I / i of the invention, 1lli The
invention is the Jl- concerning the reverberation-applying j #) modified Jl in the case of IIIIi in the
head ν. In the conventional reverberation even wc, one reverberation adder as shown in FIG. 2 is
used, but O is the sum of the left and right signals in the case of the input deviation 8.81 f stereo)
addition of the reverberation adder 1 , The output is amplified by increase 111B, and the left and

the left and right headphones a can not have the same pressure as the reverberation partial
pressure. . Chuo □ electric potential, shift, t ッ ッ. 1あ。 In the case of two reverberation adders
such as Lr 亦 B and so on, one signal is added by the respective signals a, s' and reverberation
adder 1.1 of the left and right channels. The output is amplified, amplified by 1 ′ nz 2, mixed
with the original signal by mixed H & III respectively, amplified by @ H 41 a ′ c, and added to
each other for t 3 ゲ. ζogH11, c at the left signal 8 qI or left ear 50 findings potential, and also

Δ-03 However, the actual reverberation tube is a part of the sense of localization 1k (,
nondirectional It is a sense of sense, and even with the conventional f) device the IK burn signal
comes from meticulous care. As a real sense, it is a reverberation sound and Fi puss in 1ki ones
Oh. In the case of adding a signal of headphone L reverse homology size of one both ears in the
case of a stone to be listened to by 亦 headphones 011 ear, it becomes an unknown road or is
either localization or an invisible road, and the sound image is buried.
Therefore, the present η M is an improvement over the conventional imperfection of
reverberation #IK by 1 point, and the sum or difference signal of the left and right input signals
S, s + is added to the reverberation n1 as shown in FIG. In addition, the reverberation signal is
created by the pupil, amplified by @ 82, this is added to the left and right original signals, left and
right reverse phases, added and mixed by the mixed fog & 、, amplified by amplification I441,
and each is O @ V headphone 515I Let's add it, because it is a large bowl. The localization of the
original signal from the 11WK is the same as conventional) left and right respectively O 彊 纜 1

component of the left and right antiphase sound localization 11 ° I can not be extended and
spreads all over the back of the head, from among them the -1 sound There is a feeling that it is
floating, and it is possible to get a rich reverb effect near to a sense of presence C. The above
