Abstract
To meet the characteristic diversity need of noise source in the product sound quality research, a parameter-controlled noise generation method is presented. The developed method is based on speech signal processing and programming. The system architecture of the controllable noise source is studied, and the implementation method of each module of the system is detailed. Modular design achieves data transfer and parameter control flexibly and conveniently between modules such as system calibration, basic acoustic signal production and conditioning, audio output control. Programming implement a controllable noise source platform based on the Visual C + + with friendly interface and reliable output.
