Claims (14)

1. Høreapparat (20, 100), der omfatter: en mikrofon (110), der er tilpasset til at modtage lyd og omdanne den til et indgangssignal; en modtager (180), der er tilpasset til at afspille udgangslyd baseret på et udgangssignal; en digital signalprocessor (120-160), der er tilpasset til at behandle indgangssignalet og generere udgangssignalet, hvilken digital signalprocessor endvidere er tilpasset til at køre en akustisk feedback-sporingsalgoritme på høreapparatet for overvågning af informationer om akustiske feedback-hændelser, der indtræffer over en længere periode med anvendelse af høreapparatet, kendetegnet ved, at den digitale signalprocessor endvidere er tilpasset til at foretage annullering af akustisk multibånd eller underbånds-feedback for at reducere den akustiske feedback mellem modtageren og mikrofonen på en frekvens-bånd-for-bånd-basis, og informationerne indbefatter indsamling pr. frekvensbånd af de akustiske feedback-hændelser, der indtræffer over den længere anvendelsesperiode; hvor informationerne er tilgængelige for analyse for at bestemme aspekter af den akustiske feedback, der opleves af høreapparatet over den længere anvendelsesperiode, hvilken længere anvendelsesperiode indbefatter forskellige akustiske miljøer, der opleves af en bruger af høreapparatet under anvendelse af høreapparatet; og hvor høreapparatet kan konfigureres således, at feedback-sporingsalgoritmen køres kontinuerligt, eller aktiveres under en overvågningsperiode, eller aktiveres efter særlige programmerbare hændelsers forekomst.
2. Anordning ifølge krav 1, hvor den digitale signalprocessor (120-160) er tilpasset til at lagre de overvågede informationer i en hukommelse uden for høreapparatet.
3. Anordning ifølge krav 1 eller krav 2, hvor den digitale signalprocessor (120-160) er tilpasset til at lagre de overvågede informationer, der indbefatter én eller flere af et samlet antal forekomster af en feedback-hændelse, og et antal feedback-hændelser pr. tidsenhed.
4. Anordning ifølge et hvilket som helst af de foregående krav, hvor den digitale signalprocessor (120-160) er tilpasset til at lagre statistiske informationer om akustiske feedback-hændelser.
5. Anordning ifølge et hvilket som helst af de foregående krav, hvor mikrofonen (110) og den digitale signalprocessor (120-160) er placeret i et hus, der er tilpasset til at blive båret på eller bag en brugers øre, og modtageren (180) er forbundet med huset via ledninger.
6. Anordning ifølge et hvilket som helst af kravene 1 til 4, hvor mikrofonen (110), den digitale signalprocessor (120-160) og modtageren (180) er placeret i et hus, der er tilpasset til at passe i en brugers øre.
7. Anordning ifølge et hvilket som helst af kravene 1 til 4, hvor mikrofonen (110), den digitale signalprocessor (120-160) og modtageren (180) er placeret i et hus, der er tilpasset til at passe bag en brugers øre.
8. Anordning ifølge et hvilket som helst af de foregående krav, der endvidere omfatter trådløs elektronik, der er tilpasset til at foretage trådløs kommunikation af overvågede informationer.
9. Fremgangsmåde til overvågning af et høreapparats ydelse ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at den omfatter: kontinuerlig kørsel af den akustiske feedback-sporingsalgoritme eller aktivering heraf i en overvågningsperiode eller aktivering heraf efter særlige programmerbare hændelsers forekomst, til sporing af informationer om en flerhed af akustiske feedback-hændelser i løbet af det længere tidsinterval for anvendelse af høreapparatet til overvågning af ydelsen af enheden til annullering af akustisk feedback, der foretager annullering af akustisk feedback på en frekvens-bånd-for-bånd-basis, i forskellige akustiske miljøer, som opleves afbæreren af høreapparatet, hvor sporing af informationerne indbefatter indsamling pr. frekvensbånd af flerheden af akustiske feedback-hændelser, der indtræffer i løbet af det længere anvendelsestidsinterval; og lagring af informationerne med henblik på analyse.
10. Fremgangsmåde ifølge krav 9, der omfatter aktivering af sporingen efter forekomsten af forudbestemte hændelser.
11. Fremgangsmåde ifølge krav 9 eller krav 10, hvor lagringen sker i høreapparatet.
12. Fremgangsmåde ifølge krav 9 eller krav 10, hvor lagringen sker i et datalager væk fra høreapparatet.
13. Fremgangsmåde ifølge krav 9, 10 eller 12, hvor lagringen sker ved anvendelse af intemettet.
14. Fremgangsmåde ifølge et hvilket som helst af kravene 9 til 13, hvor informationerne indbefatter én eller flere af: et samlet antal forekomster af en feedback-hændelse og et antal feedback-hændelser pr. tidsenhed.
