Welcome to the Hearing Devices site on MedCatalog.Com. Here you will find all
types of medical products and supplies for the deaf and hard of hearing person as well as
products for their families and friends.
At Audex, we are dedicated to providing the most functional and effective
assistive listening devices for hearing impaired individuals. We also
provide this level of excellence for facilities required to offer assistance by
the Americans with Disabilities Act (ADA). Our emphasis is on quality,
ease of installation and use and reasonable cost. Our product features
reflect our in-depth knowledge of the needs of hearing-impaired people as well
as the problems experienced by facilities providing these devices under the ADA.
If your needs include hearing accessibility, Audex stands ready to offer
Neckloop Infrared Receiver
The Audex Infrared battery powered
receiver is a lightweight, convenient receiver for 95 kHz infrared reception.
This unique unit uses a top mounted volume control and a separate on/off switch
to adjust for hearing losses ranging from mild to profound. Designed with a
hearing aid type frequency response, the REC-T3 produces balanced high and low
frequencies to provide a clean, clear, understandable signal. Coupled with
improved signal-to-noise ratio, this frequency response provides significant
improvement for almost any type of audible hearing loss.
Unlike other 95 kHz infrared
receivers, the Audex LighthLink, features a built-in neck loop, is resistant to
electronic ballast lighting interference, and can be successfully used with
Audex infrared emitters in out of door locations in full daylight conditions.
Sensitivity to transmitted signals has been increased by 25%, while rejection of
indirect sunlight has been improved by almost 50%. This means the REC-T3 is the
only infrared receiver to offers these advantages while remaining compatible
with other broad band 95kHz systems. This means all of the advantages of 95KHz
broadband technology is available with this product for courts, universities,
and other government facilities.
The REC-T3 is powered by two
alkaline or NiCad rechargeable batteries, providing up to 150 hours for alkaline
and up to 40 hours between charges for NiCads. The charge jack is located on the
side of the unit, allowing the wearer to listen to the receiver while the
batteries are being charged.
The comfortable, permanently
attached neck strap, functions as a highly efficient neck loop when no transducer
is plugged into the headphone jack, providing a computer designed magnetic field
with a shaped frequency response for maximum speech discrimination results.
Plugging in headphones, cochlear implant patch cord, or other transducer,
disconnects the loop, causing the neck loop to revert to a sturdy neck strap. The
red on light on top of the unit doubles as a battery monitor, only lighting when
the battery voltage is sufficient to provide a distortion-free signal.

We offer the highest level of personal care in the
industry . . . quality, technology, customer satisfaction and reasonable cost are the
benchmarks of service . . . and our promise . . . at HearUSA.
Within an hour, a HearUSA Audiologist will find
the nature of your hearing loss, evaluate your situation and recommend the most appropriate
action. With today's technology, most hearing
losses can be treated effectively, and improve your quality of life . . . forever!
Today's hear wear comes in many different types and sizes.
The modern technology is sophisticated and
amazing! The quality has changed dramatically since the days of Alexander Graham Bell, who invented
the telephone in an attempt to produce an amplifier
for his hard-of-hearing mother!
And, the size has gotten smaller and smaller since the days when the
hearing aid was so large, the battery had to be
strapped to the wearer's ankle!
Today's hear wear has achieved CD quality sound and the size of
hearing aids are about the size of a contact lens and
are virtually undetectable.
Programmable and digital hearing aids are so
sophisticated they can automatically adjust the volume of sound without having to manually adjust
the volume controls, allowing you to experience soft sounds as well as making loud sounds more
comfortable . . . and allowing you to enjoy unlimited freedom!
MED-EL has developed a system of service second to none. The needs of cochlear
implant users are the focus of our efforts.
This system is based on upon five key commitments:
-commitment to patient support,
-commitment to professional support,
-commitment to training and education,
-commitment to maintenance and service,
-commitment to research and development.
The services provided in each area are tailored to the specific and individual needs of the
clinic and their cochlear implant users.
The COMBI 40/40+ System
The COMBI 40/40+ System consists of an implanted part and an external part. The implanted
part of the COMBI 40+ System comprises a small ceramic implant package, an electrode
array, and a reference electrode. The implant is placed permanently in the bone behind the ear,
the electrode array is inserted into the cochlea, and the reference electrode is placed outside of
the cochlea. The surgical placement of the cochlear implant takes two hours on average.
All materials used in the construction of the implant have been tested extensively for
biological compatibility and durability. The energy required by the implant is sent from the
external speech processor through the intact skin. Therefore the implant contains
no batteries or other parts that need replacement.
Ceramic Housing The implant housing is very small with all of the implant's electronic components contained in
a robust and compact ceramic case. There is no need for a mechanically stressed coil
outside the housing. Although ceramic implant housings are very expensive to manufacture,
they are increasingly becoming the material of choice in many modern medical and
Unlike metallic materials, the ceramic case of the implant does not interfere with signal
transmission and allows the transmission of a large amount of information with low energy
requirements. In addition to favorable electrical characteristics, the ceramic material used in
the implant also has very high mechanical strength and is similar in hardness to the
Electronics The electronics of the implant contain a powerful custom-made chip that is capable of
processing large amounts of information at a very rapid rate. It can generate over 18,000
sequential stimulating pulses per second and has been designed according to highest safety
and reliability standards. This makes the implant compatible with a wide range of pulsatile
processing strategies and future developments in speech processing. An advanced telemetry
feature enables the clinic to verify the functional status of the implant within seconds.
Electrode Array The electrode array is attached to the ceramic implant package and is inserted into the
cochlea during surgery. The electrode array has been designed to enable deep placement
into the cochlea with minimal trauma (approx. 31 mm) The special mechanical features of
the array facilitate bending in the desired direction during surgical placement. The 24
COMBI 40+ contacts (electrodes) are arranged as connected pairs for 12-channel high-rate stimulation. The contacts are mounted on the electrode
array in such a way that they are well positioned for stimulating the auditory nerve. The reference electrode is placed
in a well protected spot outside the cochlea.

The earmold is truly the most important link in the fitting of a hearing aid system, since it must routinely
and simultaneously fulfill numerous functions. If it fails in any one of them, the hearing aid fitting can fail.
-Provide a satisfactory acoustic seal
-Acoustically couple the hearing aid to the ear
-Retain the hearing aid on the pinna
-Modify the acoustic signal produced by the hearing aid
-Be comfortable to wear for an extended period of time
-Be aesthetically acceptable to the patient, and
-Be of a style that the patient can physically handle
Microsonic’s Custom Earmold Manual and Instructional Video Earmold Selection and Acoustics detail
the selection of materials, styles, acoustic options and applications. You can learn more about
materials and styles here by going to Guide to Earmold Material Selection and Guide to Earmold Style Selection.
First, though, you may want to review the Patient Evaluation for Earmold Selection.
