Abstract

The embodiment of the invention discloses a method and a system for acquiring a vibration transfer function. The method comprises the following steps: generating a first test sound signal by a test signal generation unit; generating a first sound by the sounding unit based on the first test sound signal; at least two detectors respectively output a first feedback signal after receiving the first sound at the first position and output a second feedback signal after receiving the first sound at the second position, and the first feedback signal comprises a signal transmitted to the first position from the sound production unit through a vibration transmission path and a gas conduction transmission path; the second feedback signal comprises a signal transmitted from the sounding unit to the second position through the air conduction transmission path; the feedback path calculation unit determines a vibration transfer function from the sounding unit to the first position based on the first test sound signal, the first feedback signal and the second feedback signal.

Description

[0001] Case Description [0002] This application is a divisional application for the Chinese application with the filing date of August 29, 2020, the application number of 202010891026.5, and the title of the invention "A Method and System for Obtaining Vibration Transfer Function". technical field [0003] The present application relates to the technical field of hearing equipment, and in particular to a method and system for obtaining a vibration transfer function from a loudspeaker on a hearing equipment to another location. Background technique [0004] Hearing devices (eg hearing aids) typically have both a microphone and a speaker. A portion of the sound from the speaker may be picked up by the microphone, causing howling or causing the user (eg, the wearer) to hear an echo while using the device. In order to suppress echo or howling, it is necessary to reduce the influence of the speaker on the microphone as much as possible (for example, remove the sound emitted by...
