摘要

噪音與振動是互為因果的，噪音會使結構產生振動，而振動中的結構亦會造成周遭的空氣擾動而發生噪音。本篇主旨乃是以「迴響室音場」模擬噪音環境，並針對噪音所引發機械結構之振動效應做一探討。文中先就音響試驗之「迴響室音場」做一概述，再以payload結構為例，將其分別置於噪音（迴響室音場）與振動環境下進行結構振動響應之量測，進而觀察其在振動響應上之表現並加以探討。

Noise and vibration are the cause and effect relationship. Noise and vibration in the environment or in industry are caused by particular processes where dynamic forces excite structures. The purpose of this paper is to discuss the noise-vibration relationship by means of the ｢reverberations chamber field｣. The text in the first place outlines the reverberations chamber field, Second, it takes the payload structure as a instance, observing and discussing the vibration response of structure in noise and vibration environment respectively.
