    Abstract

    Real Ear Attenuation at Threshold (REAT) was measured on 16 human test subjects in accordance with EN 24869-1. Insertion loss for the individual cups was determined in accordance with EN 352-1, paragraph 7.11-7.11.3.3. Both the REAT and the insertion loss measurements were performed in an approximated diffuse field. The field was established in a semi reverberant room with uncorrelated one-third octave bands of noise from two loudspeakers. The measurements are part of a European intercomparison project 'Sound attenuation in accordance with EN-24869-1'.
