Web亥姆霍茲共振（Helmholtz resonance）指的是空氣在一個腔中的共振現象，例如在一個空瓶子的瓶口吹氣引起的共振。在1850年代由赫爾曼·馮·亥姆霍茲設計並命名，亥姆霍茲共振器一開始的目的是為了分辨複雜聲音環境下的不同頻率，比如音樂的樂調。 WebThe Helmholtz resonance occurs at a frequency (143 Hz) substantially equal to that of the Torres guitar, because the greater volume is 'contrasted' by the larger diameter of the hole (87.3 mm). The air resonance F 1 appears at 115 Hz - corresponding to the A 2 # while the soundboard resonance F 2 occurs at 230 Hz. WebWhen a force is applied at the object’s natural frequency, it goes into resonance, and a higher amplitude vibration response is created. This article describes natural frequency and resonance.
