Electroacoustics - Simulators of human head and ear -- Part 1: Ear simulator for the measurement of supra-aural and circumaural earphones (IEC 60318-1:2009)

This document addresses the technical specifications for measuring the parameters of supraaural and circumaural headphones using ear simulators and artificial heads. It establishes standardized procedures for acoustical testing in the field of electroacoustics, ensuring consistent evaluation methods across the industry. The content focuses on defining the construction and performance criteria of ear simulators designed to mimic human ear acoustics during measurements. Detailed protocols are outlined for assessing how headphones interact with these models, covering aspects such as frequency response and sound pressure levels. By aligning with international technical frameworks, this text provides a reliable reference for manufacturers and testing laboratories. The guidelines facilitate the characterization of transducer performance without deviation, supporting the comparability of data obtained from different testing facilities. Adherence to these methods allows for the accurate determination of how sound is delivered to the ear in various headphone configurations. The scope encompasses the necessary equipment configurations and measurement techniques required to maintain uniformity in product assessment.
