Abstract

テレビや映画における効果音は欠かせないものである.効果音は集音が難しい等の理由から,多くの効果音は擬音として作成した音が使用されている.そこで,手近な道具であるコンピュータを用いて,1つの擬音から効果音を容易に生成できるかを検討する.本報告では鳥の羽ばたき音を取り上げる.鳥の羽ばたき音は鳥の体重対羽ばたき周波数の関係が明らかなことから,一つの羽ばたき音から別な鳥の羽ばたき音を内挿法によって生成できることが期待される.羽ばたき音は傘の開閉よって作成できるので,一つの傘からサイズの異なる他の傘の音へ変換した擬音が他のサイズで録音した音に対して受聴試験で検討する.その結果。別なサイズの鳥の羽ばたき音が生成できる見通しを得た.

The sound effect in a television or a movie is indispensable. Many sounds on the scene are used imitative sounds, because the original sound fitted the scene are difficult to collect. Then, we try transfer easily from the imitative sounds to another size of model by computer. In this report, imitative sounds are taken up flapping bird sounds. Since the relation between weight of birds and wing stroke frequency was reported, it is expected that another flapping bird sounds generates by methods of interpolation. As the flapping bird sounds are reported to make by opened-closed umbrella, another size of the umbrella sounds are transferred by methods of interpolation compares with recorded same size of the umbrella sounds by the hearing test. As a result, it is able to generate the flapping bird sound of another size.
