Neon - 2 Channel, 9-Band
Hearing Systems - 2
channels with more gain for quiet sounds
and less gain for loud sounds. Feedback
manager, Speech Management System (SMS)
and Microphone Noise Reduction (MNR) make
these sophisticated instruments extremely
versatile and suitable for most users’ personal
preference.
Feedback Manager
- Feedback (whistling) is caused by amplified
sound being fed back into the hearing aid
receiver, being amplified again, and being
fed back in again. This phenomenon normally
happens at the resonant frequency of the
auditory canal (about 3 KHz.) The feedback
manager dampens this frequency (and frequencies
adjacent to it) to prevent feedback occurring.
The Neon VC is a standard
behind-the-ear (BTE) hearing system that
delivers sound into the ear via an earmould.
This device features a type 13 battery,
and is very light at only 3.6g. The Neon
VC features a user controllable volume control,
and a telecoil switch. Dimensions: 12x8x36mm
The Neon PP is a high powered
behind-the-ear (BTE) hearing system that
delivers sound into the ear via an eamould.
This device features a type 675 battery,
and weights only 6.6g. The Neon PP is suitable
for moderate to severe hearing losses due
to its high output. Dimensions: 14x8x46mm
The Neon SM-VC is a digital
hearing system that fits into the ear canal
(ITE). The Neon SM-VC is custom-made from
an exact impression of the user's ear, to
ensure a comfortable and effective fit.
This device features a type 10A or 312 battery.
Dimensions: 10x6x18mm (nominal).
The Neon CIC is the smallest
hearing instrument in the Neon range, fitting
deep into the ear canal (CIC), for an almost
invisible fit in normal use. Custom-made
from an exact impression of the user's ear.
The Neon CIC features a 10A battery. Dimensions:
8x6x15mm (nominal).
The previous generation of hearing
aids utilised amplification systems based on analogue
electronic technology. These hearing aids simply took
the sounds and noises that they "heard" and
amplified them. That meant amplifying unwanted signals
also. It was possible to apply some limiting factors
to the output sound levels of these hearing aids but
in general, although they were an excellent solution
for the patients, the opportunity to use Digital Signal
Processing was a huge breakthrough.
Digital Signal Processing allows
us, the manufacturer, to do just that:- "process"
the signals that are received by the hearing aid. This
means that we can manipulate the incoming sound, and
transform it into what the user feels most comfortable
with. We can reduce unwanted noise, and concentrate
on providing the user with clearer speech signals.
All Neon hearing systems are 100%
digital and have advanced features such as feedback
management, speech management and microphone noise reduction,
features not found on analogue hearing systems.
