By changing the secondary source installation angle, the attenuation effect is tested on line so as to validate the validity of the theory. Finally, the conclusion is made that optimizing the installation angle can improve the noise suppression.</em></p><p class='subject'><strong>关 键 词：</strong><a href='/subject/article.aspx?id=1170199'
