Clarity Products for Mild to Severe Hearing Loss
Clarity Professional® products with patented Digital Clarity Power™ (DCP™) technology utilize digital signal processing to recognize and amplify conversations in a way never imagined before. DCP intelligently amplifies the human voice, eliminates distracting echoes, reduces noise and suppresses sharp, sudden sounds in telephone conversations.
With DCP, Clarity is the first company in the world to utilize digital signal processing technology for audio processing in an amplified telephone.
Digital Clarity Power has three main features:
Multiband Compression, Acoustic Echo Cancellation and Noise Reduction.
Multiband Compression
DCP uses Multiband Compression (MBC) to provide "intelligent amplification" by using proprietary algorithms to determine which incoming sounds are the human voice and provide more amplification to those sounds while suppressing other sounds.
Acoustic Echo Cancellation
With a normal amplified telephone, sound coming out of the earpiece is picked up by the mouthpiece and reprocessed, creating a feedback loop which listeners notice as an echo or, in worst cases, squealing. DCP uses Acoustic Echo Cancellation to recognize that the sound in the loop has already been processed and breaks the feedback loop.
Noise Reduction
All telephones, amplified or not, have some amount of noise inherent to the system. In addition, most telephones also transmit background noises. While typical amplified telephones often increase these sounds, DCP utilizes Noise Reduction software to suppress them, making conversations more comfortable than ever before.
