The way to recommend VELVET X-Mini by HANSATON. - Puretone

The highlights.
VELVET X-Mini:
Top-class technology, exclusively for your most demanding customers.
The Acclimatisation Manager.
The Active Feedback Block.
The Situation Optimizer.
The Natural Sound.
The optimal fitting based on the hearing loss is frequently
rejected by the customer. The sound or volume may be
rejected depending on the individual hearing experience
of the customer.
The Acclimatisation Manager makes allowances for this
effect. Based on the optimal frequency response, this function
of the VELVET X-Mini determines a pleasant acoustic
setting for the customer as a starting point for the automatic
acclimatisation.
A number of predefined modifications are available for
this process based on the target frequency response and
taking into account the different needs of first time and
follow-up hearing instrument wearers (Starting point, Too
shrill, Too loud, Increasement of spontaneous acceptance).
To enable highly individual settings, the start frequency
response of the automatic acclimatisation can also be
programmed freely. Over a defined period (2 weeks, 2
months, 6 months) the VELVET X-Mini system moves automatically
closer to the previously determined optimal frequency
response. The progress of the acclimatisation and
the change in frequency response can be monitored at any
time, making this system the ideal support for professional
fitting.
VELVET X-Mini uses the new generation of phase cancellation
feedback management systems.
The system works quickly and reliably to ensure that feedback
is prevented even in critical acoustic situations. The
required amplification and sound quality remain unchanged.
This is achieved with a technology which enables safe
differentiation between feedback and natural signals such
as music and therefore successful cancellation of feedback.
The signal given off in the ear is „marked“ automatically
by the system. The „mark“ can be recognized by the
VELVET X-Mini signal processing system when the sound
leaves the ear and the signal therefore can be quickly and
safely classified as feedback. This ensures that feedback
is always eliminated completely without influencing the
wanted sounds.
VELVET X-Mini recognizes different environment situations
(speech, background noise, speech in background noise,
music) and carries out the necessary control processes.
In the case of music, the system switches to an omnidirectional
microphone characteristic and adaptive parameters
are deactivated. For speech in background noise, the
directional microphone characteristic is activated and the
adaptive parameters function completely. The goal is to
offer customers optimal automatic setting of the microphone
characteristics and control parameters at all times
and in any situation.
The Situation Optimizer expands this function to include
automatic modification of the frequency response based
on the classification result. This enables a completely
different frequency response to be activated for different
situations without the hearing instrument wearer having to
change the programme manually. This offers an additional
benefit with regard to sound and speech intelligibility
in environments where the acoustic characteristics differ
greatly.
The software offers several different predefined levels of
frequency response adjustment based on environment
recognition. It is also possible to programme frequency
response adjustment individually for each recognized
situation.
With BTE systems, sound is received not in the ear but
above the ear. This means that the natural influence of the
sound by the outer ear (pinna effect) is neutralized completely
and the signal sounds less natural. The ability to
localize sound sources continues to be influenced as the
natural directional effect is also impaired.
Natural Sound copies the natural behaviour of the ear. A
„spatial omnidirectional“ microphone is created, offering
a natural sound and increased satisfaction. Natural Sound
also establishes a natural directional effect (low frequencies:
omnidirectional, high frequencies: directional), enabling
the hearing system wearer to recognize easily whether a
signal is coming from the front or behind.
Natural Sound works in combination with the adaptive
microphone system. In omnidirectional mode, users can
take advantage of the benefits of Natural Sound.
In directional mode, up to 4 frequency-dependant sound
sources are hidden. The optimal VELVET X-Mini microphone
characteristic is set automatically depending on the hearing
situation.
