    Abstract

    It is recognised that A-weighted measurements of sound pressure levels and sound power levels alone are insufficient for measurements in relation to product sound quality and noise annoyance potential. This has led to increasing interest in measures in c loser agreement with human sound perception as e.g. loudness, sharpness roughness. Equipment, which gives easy and reliable measurements of loudness and other psychoacoustic parameters, is now available, and therefore there is a need to supplement existi ng measurement methods with procedures for measurement of loudness etc. In the existing ISO-standards for measurements of A-weighted sound pressure levels and sound power levels, measurement positions are not defined with the purpose of giving meaningful measurements of e.g. loudness. Part 1 of this NORDTEST guideline gives instructions on how to supplement the A-weighted data with meaningful results of measurements of loudness.
