Abstract
En 中文
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 transmission. This method employs the artificial head technique, in which the head related transfer function was taken into account to the outer ear simulation phase. First, a bionic artificial head was designed as the outer ear model with considering the outer sound field in view of theory and physical explanations. Then the auditory peripheral simulation model was built, which mimics the physiological functions of the human hearing, simulating the acoustic signal transfer process and conversion mechanisms from the free field to the peripheral auditory system. Finally, performance comparison was made between the proposed SQOE method and ArtemiS software, and the verifications of subjective and objective related analysis were made. Results show that the proposed method was economical, simple, and with good evaluation quality.
