Abstract : A new theory for estimating the response of a complex structure is reviewed. This theory is based on a modal energy balance between the excitation and the structure. The theory is general enough to apply to vibratio excitation as well as to acoustic excitation. The t eory is applied to a simple structure, a box, simulating an electronic package excited by a reverberant acoustic field, and is verified for this case by experiments. Some refinements of the experimental technique are indicated. A formulation of the equival nce between vibration testing and acoustic testing is offered. The importance of developing such a formulation is demonstrated by showing the economy resulting from its application. Criteria ar presented for pecifying acoustic tests. The dimensions and power requirements of reverberant room test facilities are derived. Experimental results jus ify the derivations. Results of vibration tests of a microelectronic circuit and a field effect transistor are given. (Author)
