On the behaviour of artificial head transfer system applied to acoustic evaluation researches for halls

Chinese Journal of Acoustics 1993年第3期12卷 235-244页

作者： XU Yong WANG Binglin(School of Architecture. Tsinghua University. Beijing 100084)

The author has made tests for an artificial head transfer system which is modelled on a Chinese male on its main physical behaviour such as frequency responses, frequency response differences between the front and the rear incidences, as will as on its important hearing behaviour such as localization, the perception of distance and room dimensions. The results verify that this kind of artificial head transfer system can be used as one of effective tools of acoustic evaluation researches for halls.

Based on auditory peripheral simulation model, a new Sound Quality Objective Evaluation (SQOE) method is presented,which can be used to model and analyze the impacts of head, shoulder and other parts of human body on sound wave *** method employs the artificial head technique, in which the head related transfer function was taken into account tothe outer ear simulation ***, a bionic artificial head was designed as the outer ear model with considering the outersound field in view of theory and physical *** the auditory peripheral simulation model was built, which mimicsthe physiological functions of the human hearing, simulating the acoustic signal transfer process and conversion mechanismsfrom the free field to the peripheral auditory ***, performance comparison was made between the proposed SQOEmethod and ArtemiS software, and the verifications of subjective and objective related analysis were *** show thatthe proposed method was economical, simple, and with good evaluation quality.
