Extending bandwidth — SoundBrilliance

SoundBrilliance™, another innovative algorithm from Siemens, is designed to exceed the limitations of conventional hearing instrument bandwidths to offer users a listening experience more similar to that of normal-hearing individuals. SoundBrilliance analyzes input signals and adds artificial high frequencies to the output up to 12 kHz. The perceived effect is a more “brilliant” sound quality. SoundBrilliance is especially beneficial when listening to music, and also when using audio streaming via Bluetooth. This is because the bandwidth of Bluetooth transmission is limited to 7.5 kHz, but SoundBrilliance adds frequencies up to 12 kHz.

SoundBrilliance™ adds ultra-high frequency information to a hearing instrument.

Because SoundBrilliance does not operate on high-frequency components above 8 kHz from the microphone signal, but generates them from lower frequencies, these additional high frequency sounds are available without any feedback risk. With SoundBrilliance, the output in high frequencies can be increased up to 90 dB SPL in this frequency region. In terms of hearings loss, this means that hearing losses up to 85-90 dB at 8 kHz can benefit from the SoundBrilliance feature.
