High Speed Wireless Internet

A note about our handsets:

These handsets have been tested and rated for use with hearing aids for some of the wireless technologies that they use. However, there may be some newer wireless technologies used in these phones that have not been tested yet for use with hearing aids. It is important to try the different features of these phones thoroughly and in different locations, using your hearing aid or cochlear implant, to determine if you hear any interfering noise. Consult your service provider or the manufacturer of the handset for information on hearing aid compatibility. If you have questions about return or exchange policies, consult your service provider or phone retailer.

HAC Ratings: 

Hearing aids do not always function well with wireless handsets.  Hearing aids operate by using a microphone to pick up sound waves, converting the sound waves into electrical signals to be amplified.  Distortion or amplification of unwanted sound (noise) often occurs

The standard for compatibility of digital wireless phones with hearing aids is set forth in American National Standard Institute (ANSI) standard C63.19. The FCC’s hearing aid compatibility requirements address hearing aids that operate in either of two modes – acoustic coupling (“M” rating) or inductive coupling (“T” rating).  Hearing aids operating in acoustic coupling mode receive through a microphone and then amplify all sounds surrounding the user, including both desired sounds, such as a telephone’s audio signal, and unwanted ambient noise.  Hearing aids operating in inductive coupling mode turn off the microphone to avoid amplifying unwanted ambient noise, instead using a telecoil to receive only audio signal-based magnetic fields generated by inductive coupling-capable telephones . A digital wireless handset is considered hearing aid-compatible for inductive coupling if it meets a "T3" (or "U3T") rating under the ANSI standard.  The FCC’s “M” and “T” ratings indicate whether a handset can be expected to function well with a hearing aid and are generally marked clearly on the handset packaging.  The “M” or “T” rating does not guarantee that the handset will function without distortion or noise, so Duet recommends that you test the handset before purchasing. The ANSI standard also provides a methodology for rating hearing aids from M1 to M4, with M1 being the least immune to RF interference and M4 the most immune. To determine whether a particular digital wireless telephone is likely to interfere with a particular hearing aid, the immunity rating of the hearing aid is added to the rating of the telephone. A sum of four would indicate that the telephone is usable; a sum of five would indicate that the telephone would provide normal use; and a sum of six or greater would indicate that the telephone would provide excellent performance with that hearing aid.

 

Levels:

Duet offers HAC-compatible handsets and devices in all major price categories, including low-cost (“C” level) (<$100), moderate-cost (“B” level”) ($100-$250), and high-end/feature-rich (“A” level) (>$250).  Costs generally correlate with the number of features, but, if though experience, Duet finds that a certain handset contains features that work well with hearing aids, such as volume control, it will be labeled accordingly with an “A” level for functionality.  Duet's sales staff is trained to assist all existing and prospective customers looking for a HAC-compliant device/handset.  HAC-compatible handsets and devices vary in their inherent “levels of functionality,” but typically at least one (1) HAC-compliant handset/device with features and services typical of its price category can be found that meets each customer’s price range.

Wi-Fi Stuff:

All hearing aid-compatible handsets with the Wi-Fi air interface have not been tested for hearing aid compatibility with respect to its Wi-Fi voice operation.
