SECTION ONE | CLINICAL GUIDANCE

With the CP810 Sound processor, the clinician can lock out the ability to

change both sensitivity and volume via the Remote Assistant. Using Custom

Sound software, the clinician can choose to allow the recipient to have access

to sensitivity only, volume only, both sensitivity and volume, or neither option

on their Remote Assistant.

Other processors have volume controls (SPrint and ESPrit series). On the

SPrint, use the Select button until the volume symbol appears on the LCD,

then press the up button to increase loudness and the down button to

decrease. On the ESPrit series, the rotary control can be programmed as either

a sensitivity control or a volume control.

1.12.1 ADRO

ADRO

is a digital pre-processing algorithm designed to make soft sounds

more audible and to maintain comfort for loud sounds. It was developed by

researchers in Melbourne

1, 2

. ADRO varies the gain in each channel by statistical

analysis of three levels: the input level, the level of background noise, and the

level of the loudest sounds. ADRO estimates these long-term output levels

for each frequency band and compares these estimates to target values.

This information is used to determine whether the gain on the channel in

question should be increased or decreased. This means that ADRO continually

adjusts the frequency response according to the input frequency spectrum.
