Description

30 532 375 2 bart buller såsom motorbuller, propellerljud och liknande. Genom att den digitala signalbehandlingen kan utformas på ett sådant sätt att den söker upp det regel- bundna återkommande bullret kan utsläckningen av detta göras mera effektivt än vad som är möjligt med analog Signalbehandling.
Kombinationer av analog och digital Signalbehandling är också kända och bygger på användningen av mikrofonen invändigt i skyddskåpan.
Det ljud, som träffar den invändigt i skyddskåpan anordnade mikrofonen har passe- rat genom den passiva bullerdämpningen varfor det repeterbara bullret är dämpat och kan vara maskerat av det slumpmässiga, icke-repeterbara bullret. Detta innebär problem för den digitala signalbehandlingen att spåra och följa det repeterbara bull- ret, så att även detta kan utsläckas med god verkan.
PROBLEMSTÄLLNING Den föreliggande uppfinningen har till ändamål att så utforma det inledningsvis antydda hörselskyddet att detta eliminerar nackdelarna hos tidigare känd teknik.
Speciellt har uppfinningen till ändamål att så utforma hörselskyddet att detta med mycket stor effekt förmår släcka ut även repeterbart buller invändigt i skyddskåpan.
PROBLEMLÖSNING Den till grund för uppfinningen liggande målsättningen uppnäs om det inlednings- vis antydda hörselskyddet kännetecknas av en andra mikrofon anordnad utanför den passiva bullerdämpningen och ansluten till den digitala signalbehandlingsanord- ningen. l0 15 20 25 532 P79 RITNINGEN Uppfinningen skall nu beskrivas under hänvisning till bifogad ritning, vilken visar ett förenklat, principiellt schema över uppfinningsföremålet.
F ÖREDRAGEN UTFÖRINGSFORM På ritningen avser hänvisningsbeteckningen l (innanför den med streckade linjer visade rektangeln) det inre av en skyddskåpa med åtminstone viss passiv buller- dämpning. Hänvisningsbeteckningen 2 avser ett utrymme på skyddskåpan men utanför dennas passiva bullerdåmpning. Den passiva bullerdämpningen är utförd för att i huvudsak dämpa ut högre 'frekvenser ner till frekvenser i området 200-300 Hz. invändigt i skyddskåpan 1 är det anordnat en niikrofon 3, en högtalare 4 och en analog signalbehandlingsanordning 5. Mikrofonen 3 ger en insignal till den analoga signalbehandlingsanordningen 5, vilken fasvänder signalen och förstärker den till- ràkligt mycket för att högtalaren 4, som drives av den analoga signalbehandlings- anordningen 5, skall kunna avge ett ljud som släcker ut det buller, som finns invän- digt i skyddskåpan 1. Härvid är signalbehandlingsanordningen 5 utförd på ett sådant sätt att den prioriterar utslåckning av lågfirekvent buller, företrädesvis buller under ca 200800 Hz.
Det framgår av ritningen att mikrofonen via en ledning 6 också är ansluten till en digital signalbehandlingsanordning 7, vilken rent fysiskt kan vara anordnad på ut- sidan av skyddskåpans passiva bullerdämpning och invändigt i en därfiir anordnad inneslutning 2. Den digitala signalbehandlingsanordningen är utförd för att spåra regelbundet återkommande ljud, exempelvis motorljud eller propellerljud, lör att via en ledning 10 till högtalaren 4 avge en signal som släcker ut sådant regelbundet återkommande ljud invändigt i skyddskåpan 1. 10 15 20 532 379 4 Det buller, som mikrofonen 3 invändigt i skyddskåpan 1 tar upp, år ett restbuller, som finns kvar efter bullrets passage genom den passiva bullerdåmpningen. Detta buller innehåller såväl repeterbart buller som icke-repeterbart, slumpartat buller, där det repeterbara bullret kan vara delvis bortdåmpat och dessutom mcr eller mindre maskerat av det slumpmässiga bullret. Detta innebär att den digitala Signalbehand- lingsanordningen i vissa situationer kan ha ett problem med att spåra och identifiera det repeterbara bullret.
Enligt uppfinningen finns på utsidan av skyddskåpans 1 passiva bullerdämpnin g en andra mikrofon 8, vilken år ansluten till den digitala signalbehandlingsanordningen.
Rent fysiskt år den yttre mikrofonen 8 anordnad i en inneslutning på utsidan av skyddskåpans 1 passiva bullerdämpníng tillsammans med den digitala signal- behandlingsanordningen 7.
Den digitala si gnalbehandlingsanordningen 7 är utförd på ett sådant sätt att när det gäller att spåra och identifiera det repeterbara bullret, så prioriteras den yttre mikro- fonen medan den inre mikrofonen fastlägger amplituden på den utsläckningssignal, som skall avges via högtalaren 4.
Av ritningen framgår vidare att det invändigt i skyddskåpan 1 kan finnas ytterligare en högtalare 9, vilken kan vara en högtalare i en kommunikationsradio.
