Audiometers; part 1: pure-tone audiometers

This document outlines the technical specifications and requirements for audiometers used in pure tone audiometry. The standard establishes the essential performance criteria, measurement methods, and safety provisions necessary for devices designed to measure hearing thresholds. It covers the definition of key acoustic parameters, including frequency ranges, sound pressure levels, and calibration procedures. The text details the operational characteristics of the equipment, ensuring consistency and reliability in diagnostic testing across different environments. Specific sections address the accuracy of output signals, the behavior of stimuli generation, and the limits of acceptable deviation during operation. Furthermore, the document provides guidelines for the testing and verification of these instruments to confirm compliance with established benchmarks. By adhering to these principles, manufacturers and users can ensure that the equipment functions correctly and delivers precise auditory assessments. The standard serves as a comprehensive reference for defining the capabilities and limitations of modern audiological tools, facilitating interoperability and quality assurance in clinical settings. It focuses on the fundamental aspects of device design and performance without extending into procedural guidelines for administration.
