ReSound said the ReSound Alera Configurable BTE 77/87 can be converted to a very small high power instrument, with one housing for both.
The BTE provides patients with an adaptable hearing instrument solution should their hearing change over time.
In addition to this clinical benefit, the Configurable BTE also provides a directional response for better hearing in background noise.
When the microphones are accurately aligned in the horizontal plane when worn on the ear, the optimal directional response can be attained.
Low frequencies are processed with an omnidirectional response, and high frequencies are processed with a directional response.
This specific processing mimics the natural directional response of the unaided ear, and yields a directivity index, or measure of how directional the instruments are.
