Audio-Mixing - Advanced Bionics AURIA Product Manual

Audio-Mixing

Audio-Mixing refers to the amplification ratio between the Processor Microphone
and an auxiliary input device. Audio-Mixing allows the child's Processor Microphone
to remain on when connected to an auxiliary input, such as an active T-coil, FM
system, or iPod, with a direct connect Earhook/cable. This is important because it
enables the child to hear his own voice and sounds around him in addition to the
input from the auxiliary device. The Audio-Mixing is set for each program on the
sound Processor by the audiologist during programming. The default Audio-Mixing
recommendation is 50/50. For a description of the Audio-Mixing options, refer to
the table below.
Audio-Mixing Options Processor Microphone Auxiliary Input (i.e. FM System)
Mic only on
50/50 - Mic/Aux* on
30/70 - Mic/Aux** on (-10dB)
Aux only (Atten.) off
Aux only off
*For classroom use and the default programming setting
** For noisy environments where greater input is needed from the FM (i.e., theatre,
church, noisy restaurant, etc.)
External Telecoil
The External Telecoil (T-coil) connects to the direct connect Earhook and provides
a way for wireless communication systems to interface with the Auria sound
Processor. In order for the T-coil to be effective, the child must have access to a
looped system or a hearing-aid-compatible telephone, both of which allow the
T-coil to receive the electromagnetic field generated by these devices. If T-coil
use is attempted with a non-compatible audio device, there may be a low-level
humming or buzzing noise, or no sound at all.
The External T-Coil rotates for optimal signal reception.
The External T-Coil is also compatible with the Harmony Sound Processor and the
Direct Connect Earhook.
