The general specifications for audiometers used in assessing hearing threshold levels and conducting psychoacoustic tests utilizing speech material are laid forth in the standard known as BS EN 60645-1:2017. In the frequency range of 125 Hz to 16 kHz, it guarantees that tests conducted with various pure-tone audiometers produce consistent results. The standard also makes sure that the comparison between the tested ear and the reference hearing threshold in the results is valid. It offers a standardized method of delivering speech information to test subjects, guaranteeing consistent outcomes when using various audiometers. According to the standard, audiometers can be categorized according to their main use, mode of operation, or range of test signals. The previous editions of the standard are replaced and canceled by this fourth edition, which also incorporates the specifications for pure-tone and speech audiometers into a single document to avoid inconsistencies between many standards.
