Automatic Sound Management

The Automatic Sound Management technology of the OPUS 2 ensures that both soft and loud sounds are heard clearly and comfortably in all listening situations. While some cochlear implant systems require special switches or settings for difficult listening environments, the OPUS 2 makes all adjustments automatically.


Adaptive Sound Window

In natural hearing, the range between the softest sound a person can hear and the loudest sound that can be heard comfortably is known as the dynamic range. For cochlear implant users, this range is known as the Input Dynamic Range(IDR). The OPUS 2 provides an extended Input Dynamic Range of 75dB. The Automatically Adaptive Sound Window ensures that this range automatically adapts to incoming sounds, depending on their intensity. As a result, users hear a wider range of sounds with greater accuracy.

Dual-Loop AGC

The OPUS 2 features an Automatic Dual-Loop AGC (AGC = Automatic Gain Control) that adjusts very soft and very loud sounds so that they are heard clearly and comfortably by the implant user. This feature helps you hear soft sounds with ease, for example whispering or distant voices. It also adjusts very loud sounds so that they are not too loud
