翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Sound trap ： ウィキペディア英語版 Sound trap A sound trap is a special acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building, or between occupied spaces. In its simplest form, a sound trap consists of an offset in the ductwork to reflect the sound back to its source. This configuration is often combined with the use of sound-absorbing material inside the trap. The physical dimensions of the sound trap may be selected to tune the trap to specific frequencies of sound. As such, it is then essentially a Helmholtz resonator used as a passive noise-control device. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sound trap」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
