The Senso DIVA Hearing Aid from Widex
The company that started the digital signal processing revolution in
completely-in-the-ear hearing aids in 1996 introduced their Senso DIVA™ in
November, 2001.
The feature list for the Diva includes a chip size smaller than the
Widex Senso (which was already one of the smallest in the industry), 15
channels and 15 frequency bands, Active feedback with no activation chirp, dual
self-calibrating microphones, occlusion management, up to 4 programs, 20-35 dB
reduction of wind noise, all with the goal of achieving "clear natural
sounds".
15 channels and 15 bands
The 15 frequency bands can each be adjusted to the patient's hearing
loss by in-situ measurement, using the hearing aid in the patient's ear as the
tone generator. This gives precise fitting to the hearing loss characteristics.
These 1/3 octave bandwidth channels can have cutoff slopes as steep as 50 dB
per octave in the speech region if the hearing loss and background noise
require it, and can adjust the bandpass slope depending on the need, becoming
much less steep in quiet situations. Each of the channels has a compression
threshold below 20 dB HL, with an input compression range of over 70 dB. Multi-segmental
compression has the goal to make soft sounds audible, loud sounds comfortable,
and to enhance speech sounds. Each channel includes a sound stabilizer and an
anti-smearing system to enhance soft sounds after loud inputs and to preserve
speech contrasts.
Dual microphones
Self-calibrating dual-microphones are used to provide a
directional system that allows the Diva computer to locate and reduce
disturbing noise. The microphones continuously compare amplitude and phase with
each other and adjust their outputs to compensate for changes, even changes due
to usage. The microphone outputs are combined by the Diva computer to give an
adaptive directional listening beam, which is used to reduce unwanted
background noise, even noise that moves (like a passing car, or noise in a
restaurant). A noise classification system adjusts the response of the
microphones, to minimize noise, even working to reduce wind noise by 25 to 30
dB.
4 programs
The Diva can be programmed to have up to 4 different listening
programs (Microphone, MT, Telecoil and Music) in all models except the CIC case
style. A push button changes from one program to another. Widex assumes that
the M program will be used for nearly all situations, with all functions
performed automatically. The alternate programs would be used to provide
telephone coil capability, or perhaps a special music program. The Music
program is derived from the original fitting with the signal processing
parameters optimized for enhanced music appreciation.
Feedback Cancellations
Many different feedback cancellations systems have appeared in
hearing aids over the years, but this one is different. The Diva uses two
systems continuously: One analyzes the current feedback conditions and
eliminates that feedback over a period of seconds. It subracts the estimated
feedback signal, using much as 12 dB of gain to eliminate the path. The other
system tracks abrupt changes in feedback and reduces the gain in the affected
channel within 300 milliseconds to completely remove the "chirp"
commonly heard when something comes close to your ear (like a phone or a party
hug). The first system adjusts after a few seconds, and the quick acting system
can relax. Together, these two system solve feedback problems without
sacrificing gain. [Of course, you still have to put the hearing aid in your ear
properly, and the case must fit your ear shape.]
Occlusion Manager
The Diva allows the audiologist to adjust the frequencies below
600 Hz without changing any of the parameters at higher frequencies. This helps
the audiologist reduce the occlusion effect.
The Widex Senso Diva is an exciting hearing aid that uses
digital signal processing to provide a natural clear sound without artifacts or
smearing of sounds. Widex calls this High Definition Hearing™.

ON A PERSONAL NOTE: I HAVE BEEN HEARING IMPAIRED FOR TEN YEARS AND USED A NUMBER OF DIFFERENT SYLES AND BRANDS OF HEARING AIDS. I BOUGHT THIS SET FOR MYSELF BUT I AM TOTALLY DEAF ON THE LEFT SIDE SO ONLY NEED THE RIGHT HEARING AID. I HAVE AUTO IMMUNE INNER EAR DISEASE AND AN 80% LOSS AND IT WORKS AWESOME!! OF COURSE THE RESULTS MAY VARY DEPENDING ON YOUR TYPE OF HEARING LOSS AND OTHER CONDITIONS. I AM NOT A HEARING AID PROFESSIONAL AND THIS IS MY OPINION BASED ON PAST EXPERIENCE.
