1.1 Izpostavljenost zvoku je fizikalni kazalnik, ki se uporablja za zvočni tlak in trajanje zvoka na določenem mestu na podlagi sestavnega prekoračenja kvadrata trenutnega frekvenčno-vrednotenega zvočnega tlaka.
1.2 Ta mednarodni standard se uporablja za instrumente za merjenje frekvenčno-vrednotene izpostavljenosti zvoku zaradi neprekinjenih, občasnih, nihajočih, spremenljivih ali impulzivnih zvokov. Instrumenti, skladni s specifikacijami tega mednarodnega standarda, so namenjeni za merjenje izpostavljenosti zvoku pri osebah, ki jih nosijo.
Meritve izpostavljenosti zvoku na delovnem mestu so lahko uporabne za ugotavljanje izpostavljenosti hrupu pri delu v skladu s standardoma ISO 1999 in ISO 9612.
1.3 Ta mednarodni standard določa zahteve glede akustičnih in električnih zmogljivosti za merilnike osebne izpostavljenosti zvoku z enotnim razredom točnosti. Razred točnosti ustreza razredu točnosti za merilnik integracijske zvočne jakosti, ki izpolnjuje zahteve tipa 2 v skladu s standardom IEC 804 za A-vrednoteno raven zvočnega tlaka v obsegu od 80 dB do 130 dB in nazivnem frekvenčnem obsegu od 63 Hz do 8 kHz.
1.4 Tolerance pri odstopanjih v zmogljivosti instrumenta od podanih načrtovanih ciljev predstavljajo učinkovitosti delovanja praktičnih instrumentov. Merilniki osebne izpostavljenosti zvoku morajo delovati znotraj toleranc iz tega mednarodnega standarda v okviru podanih okoljskih pogojev.
