Claims (13)
1. Et høreapparat (2), der omfatter en indgangstransducer (4) til tilvejebringelse af et indgangssignal (6), et højpasfilter (14), der er forbundet til indgangstransduceren og er indrettet til at tilvejebringe en højpasfiltreret del af indgangssignalet (6), et lavpasfilter (16), der er forbundet til indgangstransduceren og er indrettet til at tilvejebringe en lavpasfiltreret del (22) af indgangssignalet (6), en synteseenhed (18), der er forbundet til højpasfilterets udgang og er indrettet til at generere et syntesesignal (24), og en kombinationsenhed (20), der er forbundet til lavpasfilterets udgang og til synteseenhedens udgang og er indrettet til at kombinere den lavpasfiltrerede del (24) med syntesesignalet (24) til tilvejebringelse af et kombineret signal (26), en høretabsprocessor (8), der er indrettet til at behandle det kombinerede signal (26) til tilvejebringelse af et behandlet signal i overensstemmelse med et høretab for en bruger af høreapparatet (2), og en receiver (10) til konvertering af et audioudgangssignal (12) til et udgangslydsignal, hvilket audioudgangssignal (12) kan være det behandlede signal, eller kan være afledt af, det behandlede signal, kendetegnet ved, at synteseenheden (18) er indrettet til at generere syntesesignalet (24) fra den højpasfiltrerede del ved anvendelse af en model, der er baseret på en periodisk funktion, idet en fase for syntesesignalet (24) er i det mindste delvist randomiseret.
2. Et høreapparat (2) ifølge krav 1, hvor den periodiske funktion indbefatter en trigonometrisk funktion, såsom en sinusoide eller en linearkombination af sinusoider.
3. Et høreapparat (2) ifølge krav 1 eller 2, hvor højpasfilteret og lavpasfilteret er komplementære.
4. Et høreapparat (2) ifølge krav 1, 2 eller 3, og som er indrettet til at skifte frekvensen for syntesesignalet (24) nedad i forhold til indgangssignalet (6).
5. Et høreapparat (2) ifølge et hvilket som helst af de foregående krav, hvor randomiseringen af fasen er justerbar.
6. En fremgangsmåde for de-korrelering af et indgangssignal (6) og udgangssignal (12) for et høreapparat (2), idet fremgangsmåden omfatter, at opdele indgangssignalet (6) i en højfrekvensdel og en lavfrekvensdel, generere et syntesesignal (24), og kombinere syntesesignalet (24) med lavfrekvensdelen, kendetegnet ved, at trinnet for at generere et syntesesignal (24) udføres på basis af højfrekvensdelen og en model, idet modellen er baseret på en periodisk funktion, hvor en fase for syntesesignalet (24) er i det mindste delvist randomiseret.
7. En fremgangsmåde ifølge krav 6, og som omfatter, at opdele højfrekvensdelen i en flerhed af segmenter, der kan være overlappende, gange hvert segment af flerheden af segmenter med en vinduesfunktion og transformere til frekvensdomænet, og selektere de N højeste toppe i hvert segment, hvor N kan være mindst 2, hvor det at generere syntesesignalet (24) omfatter, eller udføres ved, at erstatte de selekterede toppe med den periodiske funktion.
8. En fremgangsmåde ifølge krav 7, hvor det at generere syntesesignalet (24) omfatter at anvende frekvensen, amplituden og fasen for hver af de N toppe.
9. En fremgangsmåde ifølge krav 8, hvor det genererede syntetiske signal (24) skiftes nedad i frekvens i forhold til indgangssignalet (6) ved at erstatte hver af de selekterede toppe med en periodisk funktion, der har en lavere frekvens end frekvensen for hver af toppene.
10. En fremgangsmåde ifølge krav 8 eller 9, hvor fasen for syntesesignalet (24) i det mindste delvist randomiseres ved at erstatte i det mindst nogle af faserne for nogle af de selekterede toppe med en fase, der er valgt tilfældigt eller pseudo-tilfældigt fra en uniform fordeling over (0, 2π) radianer.
11. En fremgangsmåde ifølge krav 10, hvor randomiseringen af faserne er justerbar.
12. En fremgangsmåde ifølge krav 10 eller 11, hvor randomiseringen af faserne udføres afhængigt af stabiliteten for høreapparatet (2).
13. En fremgangsmåde ifølge et hvilket som helst af kravene 6-12, hvor den periodiske funktion indbefatter en trigonometrisk funktion, såsom en sinusoide eller en linearkombination af sinusoider.
