摘要： A system, device and method to condition a wide-band calibration stimulus such as a chirp or logarithmic chirp with the purpose of reducing the dynamic range necessary for an acquisition system of an audio wearable device. The dynamic range of the stimulus is compressed using a temporal envelope and digital filters to prevent the high magnitude of the resonance peaks from clipping or saturating the response signal. Such pre-conditioning method for the calibration of the audio wearable device may allow the use of a low -depth or low-resolution acquisition system to perform the measurements.
