<p>This hearing aid device (1) uses a hearing aid (3) for a low-frequency range and a hearing aid (2) for a high-frequency range. A controller (6) compares the sound pressure of the high-frequency band of the hearing aid (2) for a high-frequency range, the high-frequency band having been divided by a bandwidth divider (10), and the sound pressure of the high-frequency band of the hearing aid (3) for a low-frequency range, the high-frequency band having been divided by a bandwidth divider (15), and increases the sound pressure of the high-frequency-side band of the hearing aid (3) for a high-frequency range in the case that the sound pressure of the high-frequency band of the hearing aid (3) for a low-frequency range is equal to or greater than a predetermined value of the sound pressure of the high-frequency band of the hearing aid (2) for a high-frequency range.</p> |
