摘要:
Experimental and theoretical attenuation characteristics are presented for broadband and pure tone acoustical signals between 300–1200 cps traveling through long pipes with rigid walls. Close correlation was found between experimental and theoretical attenuation rates over the entire system; however, an unexpected, almost constant attenuation factor was found in 90° side branches. The experimental work was sponsored by the American Gas Association as part of a sonic‐leak pinpointing project.
