Abstract

En anordning til oppnåelse av et av ytre akustiske betingelser upåvirket frekvensforløp i høreinnretninger i kommunikasjonsterminaler benytter som elektroakustisk omformer en dipolomformer som er anordnet slik i et hus at det sikres et fritt utløp av lydbølgene fra for- og baksiden av dipolomformeren.
