Abstract

Et lydopptaks- og reproduksjonssystem for et hodesett i et støyfylt miljø, omfattende, på lydopptakssiden, i det minste én mikrofon (20) fulgt av en samplingsinnretning (25), en desimator (26), en innretning (27) for kompensa- sjon av signalforvrengning som oppstår i hele den opp- strømsrelaterte akustiske kjede, og på reproduksjons- eller lytte siden, en interpolator (5) fulgt av en inn- retning (6) for kompensasjon av defektene ved audiometri- en hos operatøren (6) og av en aktiv støyreduserende sløyfe (10, 11, 7, 12, 13, 14).
