Phonak frequency compression
WebJan 4, 2007 · Frequency Compression Frequency compression is another amplification strategy for high-frequency hearing losses that has been available but used rarely until recent years. WebMay 31, 2016 · Phonak research data suggests improved audibility for high frequency sounds using SoundRecover2 When applied to speech signals, this strategy leaves vowels intact while allowing compression of important high frequency information in fricatives down to sufficiently low output frequencies (Figure 2).

WebMay 16, 2016 · Frequency compression squeezes the high frequencies into a smaller lower frequency region, thus resulting in sound that differs more than the original. Linear transposition is used in a feature known as the Audibility Extender from Widex to move sounds down to lower frequency areas. It selects a ‘start’ frequency based on the user’s ... WebPhonak’s proprietary frequency compression technology, SoundRecover, is currently available in various hear- ing aids from the manufacturer. This type of signal processing compresses the high-frequency bandwidth of the hearing aid s ignal into a region of usable hearing for a given listener (Simpson, Hersbach, & McDermott, 2005).
Webgies use one of three basic techniques: compression, transposition, and composition (Fig. 1). With frequency compression (e.g. SoundRecover by Phonak) high frequen - cies are brought to lower frequencies by squeezing fre-quency content toghether in a smaller space. This is done for sounds above a selected start frequency, and distortion WebA follow-up experiment with NFC used Phonak's Naída SP V BTE, which could also lower a greater range of input frequencies. Results: Consistent with previous findings, …
