When sounds get louder, the volume change should be balanced across both ears. This is especially important in noisy settings where loudness differences help you filter out background noise.
Our audio processors are designed to provide a close match to natural loudness growth. This makes it easier to match any hearing aid, but also provides a wide dynamic range for loudness growth. This means the person talking
to you in a busy room can be heard over the background noise of the room.
Other systems may use a higher compression ratio (e.g. 12:1), which means the differences between louder sounds may be lost. It is also very different than a typical hearing aid compression ratio (2:1 or 3:1).
This means the volume changes between the ears will be unbalanced, unless the hearing aid is reprogrammed to have high compression. And an unnaturally high compression ratio can affect speech understanding and sound quality with the hearing
