Title:
HEARING FUNCTION TRAINING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/119505
Kind Code:
A1
Abstract:
A hearing function training device is provided with a training signal generating means
(10) for generating a training vibration signal, and a vibration transmitting means
(30) for transmitting a mechanical vibration as a bone-conductive sound based
on a vibration signal through a bone-conductive vibration element contacted with
a user, wherein the training signal generating means (10) is comprised of a hearing
test means (12) for acquiring hearing information including hearing levels
for a plurality of test frequencies in accordance with a hearing test of the user,
a spectrum determining means (14) for determining a frequency spectrum corresponding
to the hearing information, an audible signal generating means (16) for generating
an audible signal with the frequency spectrum, and a signal modulating means
(20) for modulating an ultrasound carrier signal based on the audible signal
to generate the vibration signal.
