碩士 === 逢甲大學 === 電聲碩士學位學程 === 97 === Because life quality is increasing, people are getting focus on sound quality of entertainment. People not only take account of visual entertainment, but also consider audio entertainment. Nevertheless, it is hard to tell consumers about the performance of dynamic microphone from its specification. The target of the thesis is to introduce fundamental theories of psychoacoustic including basic concepts of critical band, loudness, sharpness, roughness, fluctuation strength, tone to noise ratio, and prominence ratio to set up a set standardized sound quality parameters measurement to evaluate sound quality. Finally, the thesis gets a correlation between the evaluation of dynamic microphone by evaluation of jury test and results of sound quality metrics with Brüel & Kjær Pulse.
