魚類生態に関与する水中音の基礎的研究(第3報) : 無反響水槽壁に関する研究 Fundamental Studies on the Relations between Under-water Sound and Fish Behaviour (III) : About the Echoless-wall of Aquarium 黒木, 敏郎 105869 KUROKI, Toshiro 663 In this paper, the author describes on the results of experiments about the reflection and penetration of under-water sound and about the absorption by special liquid layer. He used carbon disulfide CS_2 as this absorptive liquid and got the conclusion as follow: - Because CS_2-layer absorbs under-water sound when internal walls of 20 cm (thickness) CS_2-layer are set up, even 1 m cubic aquarium may be used equivalently to 120 m cubic water space. It seems that these studies are very important in purpose to get results exactly on ecological experiments, especially about the auditory characteristics of fish, in small (1 m cubic order) aquarium. departmental bulletin paper 鹿児島大学 Kagoshima University 1959-02-20 VoR application/pdf 鹿児島大学水産学部紀要 7 102 105 Memoirs of Faculty of Fisheries Kagoshima University 0453087X AN00040498 https://ir.kagoshima-u.ac.jp/record/12807/files/AN00040498_v7_p102-105.pdf http://hdl.handle.net/10232/13478 https://ir.kagoshima-u.ac.jp/records/12807 jpn open access
