Advanced features
Advanced features are prescribed per program, and can be modified from their default
settings selecting from the drop down box or by moving the slider to the desired value.
The defaults are set based on the program environment, which is selected in the program
tab.
Directionality
Binaural Directionality III:
Uses ReSound 2.4 GHz ear-to-ear wireless technology to allow the hearing
instruments to work together, dynamically selecting the best microphone response for the listening
environment. Possible configurations are bilateral omnidirectional, bilateral directional or an asymmetric
omnidirectional and directional response, depending on the analysis of speech and noise detectors from
both hearing instruments. This provides the optimal combination of speech understanding in noise plus a
more natural sense of surroundings.
Natural Directionality II:
The Focus (directional) ear and Monitor (omnidirectional) ear are prescribed
based on the audiogram and any speech audiometry data that may be available.
Spatial Sense:
An omnidirectional microphone response, which mimics the human ear’s natural response
to sound, preserves spatial cues and helps with the localization of sound sources.
Soft Switching:
Seamlessly enables and disables AutoScope/MultiScope Adaptive Directionality depending
on the listening environment. The response can be either omnidirectional or directional, based on whether
noise is present and the direction of speech in the listening situation. With binaurally fit wireless devices at
the 9 and 7 technology levels, the hearing instruments synchronize microphone responses.
AutoScope Adaptive Directionality:
Enables the beam width to automatically widen or narrow depending
on the acoustic surroundings, and directs the null of the response towards the noise for better SNR benefit.
Directional Mix
All directional microphone modes have both omnidirectional and directional processing through the
frequency spectrum. The setting determines the degree of directionality in the output of the hearing
instrument(s). Directional Mix applies omnidirectional processing below a crossover frequency and
directional processing above that frequency. The default setting is prescribed depending on the hearing
instrument model selected and the degree of low-frequency hearing loss. If the patient is still experiencing
difficulty hearing in noise, increasing the Directional Mix setting may help.
Time Constants
This feature adjusts the attack and release times of the compressor. The default setting, “Syllabic,” applies
fast time constants, and the “Slow” setting applies slow time constants. It is recommended not to adjust
these time constants unless the patient has prior experience with amplification using slow time constants, or
is not doing well with speech perception with fast time constants.
