BS EN 60645 is a European standard on electroacoustics that discusses the audiometric equipment to measure auditory brainstem responses that help to diagnose suspected neurologic abnormalities.
BS EN 60645-7 is the seventh part BS EN 60645 series that applies to instruments designed for the measurement of auditory evoked potentials from the inner ear, the auditory nerve, and the brainstem, evoked by acoustic and/or vibratory stimuli of short duration.
BS EN 60645-7 defines the characteristics to be specified by the manufacturer, specifies performance requirements for two types of instruments, screening, and diagnostic, and specifies the functions to be provided on these types.
The purpose of BS EN 60645-7 is to ensure that measurements made under comparable test conditions with different instruments complying with this standard will be consistent.
Note: BS EN 60645-7 is not intended to restrict the development or incorporation of new features, nor to discourage innovative approaches. The application of electric stimuli for special purposes is beyond the scope of BS EN 60645-7.
BS EN 60645-7 on audiometric instruments for the measurement of auditory brainstem responses is useful for:
Developments in the field of diagnostic hearing measurement have resulted in several instruments designed to evaluate the auditory evoked potentials of the human hearing system which can be evoked by acoustic or vibratory signals having different spectral and temporal characteristics.
The practical use of such instruments concerns the measurement of these electric potentials and their separation from electric signals emerging from other physiological or artificial sources.
BS EN 60645-7 provides you with guidance on requirements for specific instruments, general specifications, stimulus system, test quality assuring system, measuring system, presentation of results, general requirements, marking, safety requirements, routine calibration etc. This helps you in the calibration of audiometric instruments.
The requirements and test methods provided by BS EN 60645-7 assist you in improving the performance and quality of audiometric instruments and ensuring the accuracy of measurement of auditory brainstem responses.
With obedience and compliance to BS EN 60645-7, you can enhance audiometric instruments’ efficacy and manufacture a standardized high-quality product.
