1. Fremgangsmåde til behandling af et audiosignal (i(t)), der repræsenterer en bearbejdelig repræsentation af en første lyd, hvilken fremgangsmåde omfatter: modtagelse af et første sæt (x(t)) af tidsvarierende signaler, der repræsenterer en første lyd indeholdt i audiosignalet (i(t)), hvor det første sæt (x(t)) af tidsvarierende signaler omfatter et amplitudemodulationssignal (a(t)), et bærefrekvenssignal (fc(t)), et tonehøjdesignal (fo(t)) og et FM-indekssignal (h(t)); modificering af det første sæt (x(t)) af tidsvarierende signaler ved at modificere amplituden af FM-indekssignalet (h(t)), hvorved der tilvejebringes et første modificeret sæt (x'(t)) af tidsvarierende signaler; og tilvejebringelse af et første moduleret audiosignal (s(t)), der er afhængig af det første modificerede sæt (x'(t)) af det tidsvarierende signal; hvor amplitudemodulationssignalet a(t) styrer den tidsvarierende amplitude af det modulerede signal s(t), bærefrekvenssignalet fc(t) styrer den tidsvarierende centerfrekvens af det modulerede signal s(t), tonehøjdesignalet fo(t) styrer den tidsvarierende spektrale afstand mellem sidebåndene i frekvensmodulationen af det modulerede signal s(t), og FM-indekssignalet h(t) styrer den tidsvarierende spektrale fordeling af energi i det modulerede signal s(t).
2. Fremgangsmåde ifølge krav 1, hvor modificering af amplituden af FM-indekssignalet (h(t)) omfatter forstærkning eller dæmpning af FM-indekssignalet (h(t)).
3. Fremgangsmåde ifølge krav 1, og som yderligere omfatter: tilvejebringelse af et hørbart signal i afhængighed af det første modulerede audiosignal (s(t)).
4. Fremgangsmåde ifølge hvilke som helst af de foregående krav, og som yderligere omfatter: modtagelse af audiosignalet (i(t)); og demodulering af audiosignalet (i(t)), hvorved der tilvejebringes det første sæt (x(t)) af tidsvarierende signaler.
5. Fremgangsmåde ifølge krav 3 og 4, hvor modificering af det første sæt (x(t)) af tidsvarierende signaler i det mindste delvist kompenserer for et høretab for en person.
6. Fremgangsmåde ifølge hvilke som helst af de foregående krav, hvor den første lyd indeholdt i audiosignalet (i(t)) er tale eller en tale-formant.
7. Fremgangsmåde ifølge hvilke som helst af de foregående krav og krav 3, og som yderligere omfatter: behandling på samme måde af en anden lyd indeholdt i audiosignalet (i(t)) for at tilvejebringe et andet moduleret audiosignal (S2(t), SN(t)); og kombinere det første modulerede audiosignal (s(t), si(t)) og det andet modulerede audiosignal (S2(t), SN(t)).
8. Fremgangsmåde ifølge kravene 3 og 7, og som yderligere omfatter: tilvejebringelse af det hørbare signal i afhængighed af kombinationen (c(t)) af det første modulerede audiosignal (s(t), si(t)) og det andet modulerede audiosignal (S2(t), SN(t)).
9. Apparat (20, 30, 100, 110, 120), der er indrettet til at udføre en fremgangsmåde ifølge hvilke som helst af de foregående krav.
10. Apparat ifølge krav 9, og som omfatter en multiplikator (21), der er indrettet til at modificere det første sæt (x(t)) af tidsvarierende signaler for at tilvejebringe det første modificerede sæt (x'(t)) af tidsvarierende signaler.
11. Apparat ifølge krav 9 eller 10, der yderligere er indrettet til at udføre en fremgangsmåde ifølge krav 3, og som yderligere omfatter en modulator (1, 20), der er indrettet til at tilvejebringe det første modulerede audiosignal (s(t), si(t)).
12. Apparat ifølge krav 11, der yderligere er indrettet til at udføre en fremgangsmåde ifølge krav 4, og som yderligere omfatter en udgangstransducer (125), der er indrettet til at tilvejebringe det hørbare signal.
13. Apparat ifølge hvilke som helst af kravene 9 til 12, der yderligere er indrettet til at udføre en fremgangsmåde ifølge krav 5, og som yderligere omfatter en demodulator (60), der er indrettet til at demodulere audiosignalet (i(t))·
14. Apparat ifølge krav 13, og som yderligere omfatter en indgangssignalvej, der er indrettet til at tilvejebringe audiosignalet (i(t)) til demodulatoren (60) i afhængighed af et akustisk signal, hvor indgangssignalvejen omfatter en indgangstransducer (121).
