The behind-the-ear model is the oldest currently existing model. It is a powerful, easily-handled and effective hearing aid. It is composed of three parts: the earmold, which fits in the ear canal; a hearing aid that contains the electronic components, which is placed comfortably behind the flap of the ear; and lastly, tubing that connects it all to direct the sound into the ear canal.
A High-Performance Hearing Aid
Behind-the-ear models take advantage of all the technological improvements of recent years. They are often used for severe to profound hearing loss because they can be very powerful. They significantly increase sound quality and the ability to understand surrounding sounds, including speech.
Some of these models are available with rechargeable batteries and most are also compatible with wireless communication systems to enable hearing the television and telephone.
