A conductive hearing loss is characterized by a difference of at least 15 decibels between the air conduction threshold and bone conduction threshold at the same frequency. On an audiogram, the "x" represents responses in the left ear at each frequency, while the "o" represents responses in right ear at each frequency.
Bone conduction is also a good option for someone who cannot use traditional air conduction hearing aids. [15] Bone conduction devices are also used to help people with single-sided deafness, who have a non-functioning inner ear on one side. In this situation, the device picks up sounds on the non-functioning side and sends them as vibrations ...
Bone conduction thresholds can differentiate sensorineural hearing loss from conductive hearing loss. Other tests, such as oto-acoustic emissions, acoustic stapedial reflexes, speech audiometry and evoked response audiometry are needed to distinguish sensory, neural and auditory processing hearing impairments.
A bone-anchored hearing aid (BAHA) [2] is a type of hearing aid based on bone conduction.It is primarily suited for people who have conductive hearing losses, unilateral hearing loss, single-sided deafness and people with mixed hearing losses who cannot otherwise wear 'in the ear' or 'behind the ear' hearing aids.
Bone-conduction auditory brainstem response (BCABR) are similar to air conduction auditory brainstem responses, with the main difference being that the signal is transmitted via bone-conduction instead of air. The goal of bone ABR is to estimate cochlear function and to help identify the type of hearing loss present. [2]
The ADHEAR bone conduction system is a non-surgical device that sticks to the skin behind the ear. It vibrates to send sound vibrations through the skin and the skull bone to the cochlea of the normal hearing ear. [12] The SoundBite intraoral bone conduction system used bone conduction via the teeth. One component resembled a conventional ...
Noise-induced hearing loss affects adults and kids alike. This condition develops when damage occurs to the delicate hair cells in the inner ear due to exposure to loud sounds or noises. Get more ...
When the thresholds obtained via air conduction are examined alongside those achieved with bone conduction, the configuration of the hearing loss can be determined. However, with bone conduction (performed by placing a vibrator on the mastoid bone behind the ear), both cochleas are stimulated. IA for bone conduction ranges from 0-20 dB (See ...
