~~-P' The Wiener-Ho t )f techr.iciue is "... ^firmly established as a powerful tool for 

 research in certain types of boundary value problem arising in acous.tica. 

 Typical problem v.dch may be solved exactly or asymptotically with this 

 techsique concern the sound and vibration levels generated by finite or oeni- 

 infinite planar or cylindrical surfaces, of local or extended reaction, 

 issaeroed in a coEpreasiblt fluid and subject Co acotiatic or necnanical forcing, 

 However, even the siapleet of these problems involves complications which are
