This Standard describes methods of measurement to determine the immunity of hearing aids to radiated radiofrequency electromagnetic fields, in the frequency range 300 MHz to 3 GHz, and specifies electromagnetic immunity requirements and test levels. The Standard applies to hearing aids delivering acoustic outputs and includes those worn — (a) behind the ear (BTE); (b) in the ear (ITE); and (c) on the body; and includes hearing aids fitted with induction pick-up coils.

This preliminary standard describes a head and torso simulator for hearing aid measurements. The device is intend for airbone acoustic measurements, and is not suitable for measurements which depend on vibration conduction path such as bone conduction. The head and torso simulator has been designed to provide diffraction similar to that encountered around the median human head and torso, and as such may be useful for other acoustical measurements. At present it has, however, only been validated for hearing aids, and other applications will require additional validatory studies. Some such studies have already shown that the head and torso simulator may not be suitable for the calibration of external earphones due to poor repeatability of their positioning; errors may exceed 10 dB.#,,#

The purpose of this document is to define a test method with which to characterize the steady-state frequency response and input/output characteristics of hearing aids as the input level varies. This method is particularly useful for those hearing aids that have automatic gain control or other types of adaptive circuitry.
