标准简介：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.#,,#
