Able to improve voice quality for the hard-ofhearing, a signal-processing
chip can be added to standard telephone handsets as well as wireless handsets.
The Digital Clarity Power (DCP) signal processor runs various algorithms (multiband
compression, acoustic echo cancellation, and noise reduction) to improve listening
conditions. One algorithm eliminates constant noise such as air conditioning
or static, creating a clear sound that is more conducive to conversation. Another
algorithm makes soft sounds more audible and loud sounds bearable, reducing
the strain on the person with the hearing loss. The company currently offers
two DCP-enabled phones. The corded C2210 lists for $239.95, and the cordless
C4205 lists for $149.95. Additional DCPenabled phones are in development. Contact
the company for OEM pricing.
