ClearBand is a special two-way receiver that incorporates two separate membranes in one small unit.
The audio world has long taken advantage of loudspeakers with several membranes designed optimally for different frequency ranges.
In this way, low-frequency sound can be handled by a large membrane optimised to move the amount of air needed to produce the necessary sound pressure for low frequencies.
And the high frequencies, which need a very fine and quick response, are handled by a small and light membrane that can move quickly and easily.
Of course, two membranes take up more space than one. So until recent years, using separate membranes for high and low frequency sound has not been possible in hearing aids. However, with the introduction of the ClearBand model, two-way hi-fi speaker technology packed in a micro BTE hearing aid became available to hearing aid users.
With the ClearBand two-way receiver, we extended our already broad frequency range to 10.5 kHz.
And thanks to the new technology in our newest product ranges, such as DREAM440 and SUPER440, we are able to offer an exceptionally broad audio bandwidth in models with a ClearBand receiver, stretching from 100 Hz to 11.2 kHz for transmitted sound.
Our industry-leading bandwidth has implications for speech perception in people with hearing impairment, not least for children.
An extended bandwidth provides access to a larger number of speech sounds, as several consonant sounds contain high frequency spectral information. This increased access to speech is highly important for language development in children.
Gaining access to more speech sounds may lead to a significant improvement in the development of their speech and auditory skills.
Another area where a broad audio bandwidth makes a clear difference for hearing aid users is when they listen to music. The high frequencies provide ambience and brilliance to the sound.
Thus, the sound experience will be richer with an upper limiting frequency of 11.2 kHz when listening to a hi-hat or cymbals, for instance. Similarly, an audio bandwidth stretching as far down as 70 Hz in the music program will produce a fuller bass.
