Course content
When the construction of the environmental field in which it aimed at a comfortable acoustic environment is executed, the signal processing based on the state space model shown by the generation equation and the observation equation of the sound and the vibration is done in the engineering technique. It should be a system that valued generality and the robustness of processing though the digital control is achieved by using the parameter obtained by the signal processing process. It becomes basic knowledge in controlling the acoustic environment, and the measurement, the identification method of system function of knowledge and the environment of the sound and vibration engineering, and the sound field technology and the digital signal, etc. are treated.
Purpose of class
The purpose is to become the understanding the basic knowledge in controlling the acoustic environment, the measurement, the identification method of system function of knowledge and the environment of the sound and vibration engineering the sound field technology and the digital signal, etc.
Goals and objectives
  1. It can explain the base of acoustical engineering.
  2. It can explain propagation, the measurement, and the assessment method of the sound.
  3. It can explain the technique of the digital signal processing of the sound.
  4. It can explain the identification method of the transmission system.
