The standard tapping machine〔ISO 140-7 Acoustics — Measurement of sound insulation in buildings and of building elements — Part 7:Field measurements of impact sound insulation of floors〕 has five hammers placed in a line. Each hammer is lifted and dropped in turn, creating 20 impacts per second on the floor. In the room below, a sound level meter is used to measure the sound level created by the impacts. Because the force and frequency of the impacts is known, the impact insulation provided by the floor can be determined from the sound level. == References == 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「Tapping machine」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.
