Electroacoustics - Simulators of human head and ear - Part 6: Mechanical coupler for the measurements on bone vibrators (IEC 60318-6:2007)

This specification outlines the technical requirements for a mechanical coupler designed to measure characteristics of bone conduction devices within the field of electroacoustics. The document establishes the geometric and physical specifications for a head and ear simulating device, specifically tailored for the evaluation of bone vibrators. It defines the standardized interface and coupling mechanics necessary to ensure consistent and reproducible measurements across different testing environments. The scope covers the construction of the artificial mastoid and the method for mounting the device under test to facilitate accurate assessment of performance parameters. By adhering to the defined dimensions and tolerances, laboratories can achieve alignment with international measurement protocols. The content focuses exclusively on the physical attributes and operational procedures required to utilize the coupler effectively. It serves as a reference for manufacturers and testers to validate the acoustic behavior of bone conduction transducers through a unified mechanical setup. The text provides detailed diagrams and specifications without discussing the broader implications or the origin of the publication.
