Abstract [en]

This Master thesis report describes how hearing protectors can give higher attentuation to low-frequency noise when using electronic filter and active noise cancelling technique. The method described is a feedback coupling by a digital or analog filter. The filterdesign and possibility to adjust the filtercoefficients to the inividual who is supposed to wear the active headsets are discussed. The properties that the transduers in the headsets ought to have are described.

Abstract [en]

Det här examensarbetet på magisternivå beskriver hur hörselskydd kan ge högre dämpning för långa frekvenser genom att utnyttja elektronik och aktiv bullerdämpningsteknik. Den metod som främst presenteras är återkoppling via ett digitalt eller analogt reglerfilter. Designen av detta reglerfilter och möjligheten att anpassa filtret till den individ som skall bära skyddet diskuteras. De egenskaper högtalarelementen i hörlurarna bör ha beskrivs.
