KnochenleitungsHörsysteme

Knochenleitung is a German term referring to bone conduction. It is a method of hearing where sound vibrations are transmitted directly to the inner ear through the bones of the skull. Unlike air conduction, which is the typical way we hear sound through the ear canal and middle ear, bone conduction bypasses these structures.

The principle of bone conduction is utilized in various applications, most notably in hearing aids for individuals with certain types of hearing loss. For example, in conductive hearing loss, where there are problems in the outer or middle ear, bone conduction can be an effective way to deliver sound to the functioning inner ear. It is also used in situations where traditional hearing aids are not suitable or comfortable.

The sound is typically delivered to the skull via a vibrator that is placed against the bone, usually behind the ear or on the forehead. This vibration is then conducted through the bone to the cochlea, where it is converted into electrical signals that the brain interprets as sound.

Bone conduction technology is also found in specialized headphones that do not cover the ear canal, allowing users to remain aware of their surroundings. This is beneficial for activities like cycling or running. The vibrations are transmitted to the temporal bone, which then conducts the sound to the inner ear. While the sound quality can differ from air conduction, bone conduction offers a unique pathway for auditory perception.
