Abstract

Akustisk avfølingsinnretning slik som en mikrofon eller en tynnfilmsensor er lokalisert i et strømmende medium. For å forhindre avføling av strømningsgenerert støy er avfølingsinnretningene adskilt fra strømningsmediumet ved hjelp av i det minste tretrinns skjerming. Ved en foretrukket utførelsesform er avfølingsinnretningen lokalisert innenfor en skumskjerm som er lokalisert i en ramme dekket av en vevskjerm og som igjen er lokalisert i en andre ramme dekket av en andre vevskjerm. Spandex-vev er egnet for bruk ved foreliggende oppfinnelse.
