Electroacoustics. Sound level meters - Specifications Ingestion-build-81500 Both these international standards areElectroacoustics Sound level meters Part 1: Specifications Executive summary Electroacoustical performance specifications of sound level meters. Abstract This European Standard gives electroacoustical performance specifications for three kinds of sound measuring instruments: a conventional sound level meter that measures exponential time weighted sound level; an integrating averaging sound level meter that measures time average sound level; and an
