Method and apparatus for measuring and correcting acoustic characteristic in sound field

摘要

The acoustic transmission characteristics of a sound field, such as in the passenger compartment of a vehicle, are measured by placing microphones at the positions of ears of a dummy mannequin having a sound absorbing characteristic similar to that of a clothed adult human. The transmission characteristics are then corrected, such as with an automatic graphic equalizer, to provide optimized listening conditions inside the sound field for an actual listener. The use of the invention results in a listener's perception of completely natural sound.
