MED-EL offers two types of bone conduction systems: an implant and a non-surgical device. [18] The Bonebridge bone conduction implant was the first implant on the market to offer direct drive stimulation of the bone through a transcutaneous device. [19] The current models are the BCI 602 implant and the SAMBA 2 audio processor. [20]
A middle ear implant is a hearing device that is surgically implanted into the middle ear. They help people with conductive, sensorineural or mixed hearing loss to hear. [1] Middle ear implants work by improving the conduction of sound vibrations from the middle ear to the inner ear. There are two types of middle ear devices: active and passive.
Hearing aids are incapable of truly correcting a hearing loss; they are an aid to make sounds more audible. The most common form of hearing loss for which hearing aids are sought is sensorineural, resulting from damage to the hair cells and synapses of the cochlea and auditory nerve. Sensorineural hearing loss reduces the sensitivity to sound ...
A cochlear implant (CI) is a surgically implanted neuroprosthesis that provides a person who has moderate-to-profound sensorineural hearing loss with sound perception. With the help of therapy, cochlear implants may allow for improved speech understanding in both quiet and noisy environments.
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.
Pure-tone audiometry is the main hearing test used to identify hearing threshold levels of an individual, enabling determination of the degree, type and configuration of a hearing loss [1] [2] and thus providing a basis for diagnosis and management.
The Lyric Hearing device is not a Cochlear Implant. The device is removed every few months and is replaced with a new one. Wearers can adjust the volume of the device using a magnet and a removal tool is also provided. Business Week reports that this hearing aid received a 2009 Medical Design Excellence Award. [4]
Speech Transmission Index (STI) is a measure of speech transmission quality. The absolute measurement of speech intelligibility is a complex science. The STI measures some physical characteristics of a transmission channel (a room, electro-acoustic equipment, telephone line, etc.), and expresses the ability of the channel to carry across the characteristics of a speech signal.
