Abstract

Systems and methods for determining sound-producing characteristics of electroacoustic transducers are disclosed. According to an aspect, a system includes electroacoustic transducers configured to generate sound. The system also includes an acoustoelectric transducer configured to convert sound produced by the electroacoustic transducers into one or more electrical signals. Further, the system includes a computing device configured to apply one or more patterns of electrical signals to the electroacoustic transducers to test for one or more sound-producing characteristics. The computing device is also configured to receive, from the acoustoelectric transducer, electrical signals that resulted from application of the patterns of electrical signals to the electroacoustic transducers. Further, the computing device is configured to determine, based on the received electrical signals, the sound-producing characteristics of the electroacoustic transducers for use in controlling the electroacoustic transducers to generate one or more predetermined sounds.
