The goal of this device is to give the patient two-sided hearing when true bilateral hearing is not possible. The CROS system is an alternative to traditional unilateral hearing aid fittings in which the patient receives no information from the side with hearing loss. [2]
FBAR devices using piezoelectric films with thicknesses typically ranging from several micrometres down to tenths of micrometres resonate in the frequency range of 100 MHz to 20 GHz. [ 1 ] [ 2 ] FBAR or TFBAR resonators fall in the category of bulk acoustic resonators (BAW) and piezoelectric resonators and they are used in applications where ...
If the hearing loss is significant an air conduction aid may have difficulty overcoming the dysfunction of the eardrum and middle ear bones. Bone conduction hearing device bypassing the middle ear may be a more appropriate treatment for these patients. Good transmission of sound in the bone, with reduced attenuation and distortion may be possible.
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.
SoundBite Hearing System is a non-surgical bone conduction prosthetic device that transmits sound via the teeth. It is an alternative to surgical bone conduction prosthetic devices, which require surgical implantation into the skull to conduct sound. SoundBite avoids surgery by using the teeth rather than the implanted component.
The most common device is a handheld, battery-operated device pressed against the skin under the mandible which produces vibrations to allow speech; [1] other variations include a device similar to the "talk box" electronic music device, which delivers the basis of the speech sound via a tube placed in the mouth.

The use of assistive technology and devices provides this community with various solutions to their problems by providing higher sound (for those who are hard of hearing), tactile feedback, visual cues and improved technology access. Individuals who are deaf or hard of hearing utilize a variety of assistive technologies that provide them with ...
It is typically experienced as a secondary symptom of sensorineural hearing loss, although not all patients with sensorineural hearing loss experience diplacusis or tinnitus. [ 1 ] [ 2 ] The onset is usually spontaneous and can occur following an acoustic trauma , for example an explosive noise, or in the presence of an ear infection . [ 3 ]
