He assumed geometrically the seven types of lateral line shape on account of easiness for calculation ; ①･･･linear type, ②･･･interrupted linear type, ③･･･semicircular and linear type, ④･･･stepped linear type, ⑤･･･parallel type, ⑥･･･horse-mackerel's (Trachurus') type, ⑦･･･general type. He assumed, furthermore, the values of biophysical conditions as follows ; propagating velocity of under-water sound V (=150000 cm/s), transmitting velocity of sensation by sound stimuli on a lateral nurve υ (=2600 cm/s), attenuation constant of under-water sound α^{+1} (=10^{-δ/10000}), space distance from 1st receptor to 2nd one δ (cm), length along a lateral line\nbetween the two receptors l (cm), the most suitable (sensible) frequency ν (cycle/sec). Then, he got the values in the Table 1 from the equations -\n(by physical condition) ; ν=(V/2πδ)×cos^{-1}(α^{±1}), (by biological condition) ; l≧υ/ν. By means of the diagramatic method, shown in Fig. 2, he got the audible directions in various types of lateral line as Fig. 3, ①~⑦. In these figures, the ranged length of equi-frequency arcline in dotted zone means the directional angle of audibility for the frequency sound against the original point (sensorium of fish).","subitem_description_type":"Other"},{"subitem_description":"As a result of judging these figures, he concluded as follows:\na) The maximum value of the most sensible frequency is 5200~8700 c/s, in the\nvirtical direction. b) The minimum value of the one is 112~130 c/s in the direction of body axis (a bit of upward frontally in some types). The stronger sound, however, shall not be equall to this frequency (, may be lower).\nc) The directional angle of audibility for 200~300 c/s sound is very broad. This\nmeans that this (200~300 c/s) sound may be serious for fish in these coditions.\nd) Among these seven types of lateral line, the directional audibility of semic-ircular & linear type is the most splendid and broadest ; on the other hand, the one of simple linear type is very poor and narrow. The author expected that his conclusion might be recognized with biophsical experiments, and he pointed that it was needed to use many knowledges ; for examples, the actual values of nurvous conditions (refractory period and transmitting velocity of sensation and etc. in control fish), its influences by water temperature or salinity, the utility of echoless aquarium, and the methods to pick up an active potential of lateral\nnurve under the natural stimulus of sound in water.","subitem_description_type":"Other"}]},"item_7_full_name_2":{"attribute_name":"著者よみ","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"クロキ, トシロウ"}]}]},"item_7_full_name_3":{"attribute_name":"別言語の著者","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"KUROKI, Toshiro"}]}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0453087X","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040498","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"663","subitem_subject_scheme":"NDC"}]},"item_7_text_24":{"attribute_name":"公開者よみ","attribute_value_mlt":[{"subitem_text_value":"カゴシマ ダイガク"}]},"item_7_text_25":{"attribute_name":"公開者別名","attribute_value_mlt":[{"subitem_text_value":"Kagoshima University"}]},"item_7_text_39":{"attribute_name":"旧URI","attribute_value_mlt":[{"subitem_text_value":"http://hdl.handle.net/10232/13467"}]},"item_7_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"黒木, 敏郎"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-27"}],"displaytype":"detail","filename":"AN00040498_v8_p89-100.pdf","filesize":[{"value":"5.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00040498_v8_p89-100.pdf","url":"https://ir.kagoshima-u.ac.jp/record/778/files/AN00040498_v8_p89-100.pdf"},"version_id":"b80a0ac3-bd2b-4671-8ecc-db43a807d9a9"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"魚類の聴覚特性に関する研究 II : 側線の線型による方向知覚差について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"魚類の聴覚特性に関する研究 II : 側線の線型による方向知覚差について"}]},"item_type_id":"7","owner":"3","path":["40","4849"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-08"},"publish_date":"2012-05-08","publish_status":"0","recid":"778","relation_version_is_last":true,"title":["魚類の聴覚特性に関する研究 II : 側線の線型による方向知覚差について"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2024-01-30T05:49:30.318296+00:00"}
