A sound image control device filters transfer functions H3 and H1
indicating transfer characteristics of a sound from an acoustic
transducer (8) to entrances to respective ear canals (1) and (2) as well
as filtering transfer functions H4 and H2 from an acoustic transducer (9)
to the entrances to the respective ear canals (1) and (2) and generates
second transfer functions H6 and H5 indicating transfer characteristics
of a sound to the entrances to the respective ear canals (1) and (2) from
a target sound source (11) at a location different from the sound
sources, the sound image control device being equipped with correction
filters (13) and (14) that (i) store characteristic functions E1 and E2
for performing filtering operations on the first transfer functions H1,
H2, H3, and H4 and (ii) generate the second transfer functions H5 and H6
from the first transfer functions H1, H2, H3, and H4 using such
characteristic functions E1 and E2.
