Bone conduction is the conduction of sound to the inner ear primarily through the bones of the skull, allowing the hearer to perceive audio content even if the ear canal is blocked. Bone conduction transmission occurs constantly as sound waves vibrate bone, specifically the bones in the skull, although it is hard for the average individual to ...
A third type are bone conduction headphones, which typically wrap around the back of the head and rest in front of the ear canal, leaving the ear canal open. In the context of telecommunication , a headset is a combination of a headphone and microphone .
Bone conduction headphones/sets transmit sound to the inner ear primarily through the bones of the skull, allowing the hearer to perceive audio content without blocking the ear canal. Bone conduction transmission occurs constantly as sound waves vibrate bone, specifically the bones in the skull, although it is hard for the average individual to ...
Air conduction: Sound propagated from a sound source through the air is received by the outer ear, and then transmitted via the ear drum, middle ear, and inner ear. Bone conduction: Sound from a vibrator oscillates the skull bone, and the vibration is transmitted directly to the inner ear without passing through the ear drum and middle ear.
This type of bone-conduction also involves low frequencies. As a bone vibrator vibrates the skull, the bone and cartilage of the external ear receives energy, most of which escapes the unoccluded ear. Some of this energy hits the tympanic membrane and combines with inertial bone-conduction, stimulating the inner ear. An example of this occurs ...
Sound localizes to affected ear (ear with conductive loss) in unilateral cases Rinne test: Positive Rinne; air conduction > bone conduction (both air and bone conduction are decreased equally, but the difference between them is unchanged). Negative Rinne; bone conduction > air conduction (bone/air gap)
