Description

Hearing device capable of eliminating bone conduction sound

The invention relates to a hearing device, in particular to a hearing device capable of eliminating bone conduction sound.

In the context of language learning, the learner learns his own pronunciation by receiving his own voice during the practice of pronunciation, so as to perceive the correctness of his actual voice and correct himself Pronunciation.

It is worth noting that the sounds heard by learners include air conduction sounds and bone conduction sounds. Among them, air conduction sounds are transmitted to the eardrum using air as the medium, and bone conduction sounds are transmitted to the eardrum using the human bone as the medium. The medium is different, so the bone conduction sound is different from the air conduction sound. This is why the sound recorded by the recorder (that is, the part of the air conduction sound) will be different from the sound heard when it sounds.

Therefore, if you learn pronunciation by recording, you will not be able to accurately compare the sound made by the recorder and the sound you heard when you pronounced it because of the bone conduction sound you heard, which is not conducive to the learner's learning.

Therefore, one of the objects of the present invention is to provide an auditory device that can eliminate bone conduction sound, which can overcome the defects of the above-mentioned conventional technology.
