RIONET-Meaning of symbols

Classification of hearing loss

Mild < Hearing Level 25 - 40 dB>
Moderate < Hearing Level 40 - 70dB >
Severe < Hearing Level 70 - 90dB >
Profound < Hearing Level 90 dB over >

Output limiter functions

Integrated output limiter
Very loud sounds are automatically suppressed in volume.
ARC for high frequency range
Limits output sound through a compression system.
OPC for high frepuency range
Unnecessarily loud sounds are reliably suppressed.
Adjusts maximum output gain of hearing aid.

Time rate AVC

Monitoring sound and adjust hearing aid automatically ( A series only)
Determine comfort target level in each frequency band (A series only)
Determine audibility target level in each frequency band (A series only)
Determine level of maximum gain ( A series only)
Determine maximum output Limits ( A series only)

Nonlinear adjustment functions

Determines compression ratio of output sound to input sound
.High-pitched sounds are automatically compressed for easier understanding
Low-pitched sounds are automatically compressed for easier understanding
Multi-memory function allows selection of four sets of sound quality characteristics
Adjust the level of high frequency at which compression starts being activated
Adjust the level of low frequency at which compression starts being activated
Loud sounds can be adjjusted to reduce discomfort
Determines the frequency which divides the frequency range into high and low range

Tone control functions

Low-pitched sounds or noise can be adjusted to reduce discomfort.
High-pitched sounds can be adjusted to reduce
discomfort and prevent feedback.

Noise suppression functions

HC
Digital Automatic Noise suppresor reduces gain in the low and high range when sustained ambient noise is encountered.
MC
.Ambient noise is automatically suppressed to make speech more discernible
LC
Outdoor noise can be suppressed
Noise suppression and induction coil can be switched internally
Adjust the noise reduction efficincy

Sub-gain adjustment functions

Gain can be adjusted for optimum volume.

Either-way circuit

Hearing aid determines battery polarity by itself, allowing battery to be inserted in either direction

Induction coil (T)

Catches signals from TV aid, tie-loop, telephone, etc.
and reproduces them with the hearing aid.
Input balance between microphone and induction coil can be adjusted.

External input

Sound from TV, VCR or other sources can be input directly.
