BS EN 60645-1:2017 – Audiometric Equipment

Audiometry Standards

  • Defines technical requirements for audiometric equipment

  • Covers signal generation, frequency accuracy, and output levels

  • Audiometers must be calibrated to this standard

  • H4TLT's system meets BS EN 60645-1:2017 requirements

What this standard covers


BS EN 60645-1:2017 specifies the technical performance.


Requirements for pure-tone audiometers used in hearing threshold measurement. It covers how equipment must generate and control test signals at defined frequencies and levels so audiometry can be carried out consistently.

Why it matters For audiometry results to be valid and comparable, the system producing the test signals must meet precise technical specifications. This standard helps ensure consistency across different audiometric systems and testing environments.


H4TLT alignment The H4TLT hearing test system is designed to meet the requirements of BS EN 60645-1:2017, ensuring software-generated test signals follow the same technical performance expectations as calibrated audiometric equipment. the same technical performance expectations as calibrated audiometric equipment.
