View PDF Brochure

ImpaCt Xp is the first software expandable line of DSP hearing instruments with Digital Frequency Compression.

Whats special about a software expandable DSP?

Older generation digital hearing aids could perform many tasks but their performances
could never be upgraded. To access new algorithms, (i.e. new technology) a new hearing aid had to be purchased.

In contrast, ImpaCt Xps software expandable
DSP can be upgraded again and again by simply receiving new software. This makes ImpaCt Xp the ideal solution for lifes changes.

Why Digital Frequency Compression?

The importance of hearing high frequency speech sounds, particularly the /s/ is described by Dr. Mark Ross, noted Audiologist and experienced hearing aid user: The /s/ sound ordinarily contains acoustic energy which begins around 3,000 4,000Hz and extends past 8,000Hz. Not only do conventional hearing aids not amplify these same frequencies, but the hearing loss of most people is typically poorer at these same frequencies. In other words, the hearing loss is most severe at frequencies where hearing aids are least able to amplify. And, what makes the situation worse, at least as far as the /s/ is concerned, is that the phoneme conveys more grammatical information than any other sound in the English language (think about plurals, third
person singular, contractions, etc.)

What's special about Digital Frequency

ImpaCt Xp offers individuals with high frequency hearing loss something not available in other digital instruments, Digital Frequency Compression. A patented technology, Digital
Frequency Compression, moves high frequency speech sounds like s, t, f, sh to lower frequencies where hearing is typically better.

Digital Frequency Compression together with ImpaCt Xps 17 band advanced signal processing, Voice Clarity speech emphasis,
noise reduction and feedback suppression ensure comfort, audibility and improved speech understanding.
