It is traditionally big in size and now has been streamed to a minimal size with variant technologies. This type of hearing aids come in analog, programmable and digital versions. They are powerful hearing aids that can be given to severe to profound patients which more widely used. This type of hearing aid houses on the top of the ear and goes behind the ear. A tube connects the aid to ear tip or a ear mould (customized according to the ear canal shape). This type is suitable for people of all ages and those with almost any type of hearing loss.
The CIC is one of the smallest model in hearing aids and is especially suitable if you have a mild to severe hearing loss. It is a custom made shell that contains all the electronic components. The shell is placed deep in the ear canal, making the hearing aid almost nearly invisible. For easy everyday removal, the CIC has a small extension cord attached to the outside. A CIC model works fully automatically.
The Invisible-in-canal (IIC) is one of the most advanced Invisible Hearing Aid avilable yet. Custom fit to your exact needs and unique ear canal shape, it rests comfortably deep in your ear, so only you know it’s there. The IIC may be tiny, but it comes loaded with all of our leading technology.
The ITC, fit into the ear canal. This hearing aid is used for mild to severe hearing losses.
The receiver-in-canal (RIC) model is a newer development in hearing aids and is suitable for mild to severe hearing loss. The RIC model is a very discreet, yet powerful hearing aid, which works fully automatically. A few models connect seamlessly to Mobile phone,ipods and TV.
Contra Lateral Routing of Signal (CROS) is a hearing aid technology for people with unilateral hearing. The technology allows two implementations: CROS and BiCROS. Using this technology, a hearing aid-like device on the user’s poorer ear uses its microphone to pick up sound and sends it to another instrument at the better ear. The sound is then inserted into the better ear. The CROS implementation is for a user who has relatively normal hearing in the better ear and has hearing that can't be aided on the poor ear. The receiving BTE device on the poorer ear transmits the sound to a device in the better ear. The user hears the amplified sound from the poor ear in the better ear. The user hears the sound from the better ear naturally in their better ear, without amplification. The BiCROS implementation is for a user with little or no hearing on one side and with some hearing loss in their better ear. It works just like the CROS implemenation, except that the device in the better ear is actually a fully capable hearing aid for hearing sounds from the better side that is also capable of receiving the sound transmitted from the CROS aid on the other side. Transmission in a CROS or BiCROS configuration can be via wire around the back of the neck or wirelessly via radio.
