WARP Processing™ 

Warp Processing emulates the way the unaided ear analyzes the frequencies of incoming sound and breaks them into distinct pitches.

It does this by decoding the frequencies and intensities of sounds in a nonlinear way– the same way the ear does.

Most digital techniques for frequency analysis yield constant bandwidth with uniform spacing of the bands.

But Warp Processing maps the frequencies into 17 overlapping frequency bands corresponding to the auditory Bark scale. (The Bark scale incorporates the human auditory system’s critical bandwidth as the scale unit.)

It takes time for sound to be conducted through the inner ear to the auditory nervous system. The amount of time depends on the frequency and the intensity of the sound.

Crucial differences in timing can be wiped out when sound is amplified. Among other things, this can make it more difficult for the auditory system of the hearing aid user to separate out and analyze the components of te incoming sound.

But Warp Processing breaks sound into pitches in the same pattern as the human ear. So sounds of different pitches and intensities reach the brain after the correct amount of time, thereby preserving important timing cues that help the brain to analyze the sound.
