Phonak Insight. SoundRecover2 – the adaptive frequency compression algorithm

Phonak led the way in modern frequency lowering technology with the introduction of SoundRecover in 2008. Since then, extensive worldwide field studies with adults and children have found increased detection, distinction and recognition of high frequency sounds, better speech understanding and significant improvement in intonation and overall voice quality for users. For those with more extreme severe-to-profound losses, however, including left corner audiograms and ski-slope losses, the benefits have been limited due to the restricted audible bandwidth in which frequency compression could be applied. The new SoundRecover2 algorithm aims to restore the audibility of relevant high frequency sounds while leaving intact the low frequency structures important for good sound quality. The new frequency lowering scheme retains the essence of the original SoundRecover, utilizes an adaptive algorithm and an additional cut-off frequency in order to successfully extend these benefits to those with more extreme severe-to-profound hearing loss.
