Its placement, along with a darkened faceplate, usually make it virtually impossible to see. Click for a list of hearing aid terminology . Less distortion and reduced wind noise The fit, comfort and reduced feedback of a deep canal aid makes it possible to wear it during sleep. Thus, the patient can continue to hear important sounds such as speech or alarms. With the deep fit, the discomfort of placing a telephone to the ear is virtually eliminated Because of its position deep in the canal, jaw movement during speech does not affect listening.
Less power is needed because of the instrument's close position near the eardrum.
Advanced Technology Hearing Aid circuitries employ a more scientific development in amplification electronics known as non-linear or compression amplification. The result is a hearing aid with the ability to limit the level of incoming sound volume. This delivers a more natural loudness throughout the patient's entire listening range, without getting too loud or too quiet as can be the case with conventional hearing aids. Amplifiers used in advanced technology hearing aids are predominantly from the Class D family with the benefit of longer battery life and lower distortion. Advanced technology hearing aids can also employ multi-channel technology, multiple directional microphone technology, plus Adaptive Compression and variable release compression.
