Course description
Sounds penetrates deeply into our daily life, for example, conversation, music and so on. The topics of the class are the estimation of the sound emission, the design principle of the electroacoustic transducer and the sense of hearing. Finally, you practice to calculate frequency characteristics by finite element method and digital signal processing.
Purpose of class
The class aims to be able to understand the estimation of the sound emission, the design principle of the electroacoustic transducer and the sense of hearing. Finally, you practice to calculate frequency characteristics by finite element method and digital signal processing.
