WHAT IS BONE CONDUCTION?

Structure of the auditory sense / when a sound enters into the ear,

it arrives at the eardrum and moves the eardrum to stimulate the auditory nerve, the cochlea receives the vibration and the cochlea transmits the sound to the brain through auditory nerve

Common auditory sense

The vibration of the air is transmitted to the eardrum and the sound is transmitted to the brain through the cochlea, the eardrum is a highly sensitive organ and, if it is exposed to long noise for a long time, it may be damaged resulting in loss of auditory sense.

Mechanism of bone conduction

Bone conduction has the mechanism to transmit the vibration of the bone to the auditory cochlea as a sound not passing the eardrum. It prevents the damage of eardrum and reduces the stress of the ear a person with damaged eardrum may also hear the sound.

Specific features

- As the ear is not blocked, the user may hear from surroundings and this product is suitable to avoid possible risk during field activities such as mountain climbing and jogging.

-  It does not cause fatigue or hearing ability reduction even in the case of long-time use because it is designed by ergonomics.

-  High quality sound is accomplished with no use of an amplifier.

-  As the sound is directly transmitted to the auditory organ, this product is suitable to language learning and computer online learning.

It may be used for CD, MD, MP3 and sound collector.
