| Explanations for this webpage |
In this webpage, you
can download a
source code to
calculate a
mathematical
transfer function
between an incident
point source and a
point of
outer-surface of a
spheroid (assumed to
be an ear position).
Provided transfer
function can be used
for a spheroidal
head model, and
spheroid is under a
condition of rigid
boundary. You can
calculate spheroidal
HRTF by using ¡°spheroidal_HRTF.m¡±.
the input parameters
are as flows.
Example) You can calculate spheroidal HRTF by following commend
H = spheroid_HRTF(0.1, 30, 1000, 0.0001, 0.15, -0.136, 98.7085, 1);
In this case, a
point source is
located at the
median plane, and
the elevation angle
is 60 degrees
(frontal region).
Dimensions of the
head model are 20cm
width and 25cm
height. Backward ear
offset is 15mm, and
downward ear offset
is 17mm

To calculate
spheroidal
functions, we use
the source code of
