Method of improving the acoustics of a hall

DETAILED DESCRIPTION I claim: 1.
A method of improving the acoustics of a room having a performance area in which sound is generated from a sound source and an audience listening area which is spaced from the performance area and which is defined by wall and ceiling elements, utilizing first soundboard means, the first soundboard being of a box shape configuration having a substantially planar wooden outer surface element which is mounted to a frame, the soundboard being open on the side opposite the wooden outer surface, the wooden surface element being no greater than 10 mms.
in thickness so that the wooden outer surfaces element will vibrate in response to sound waves traveling through the air thereby the first soundboard will reflect sound waves traveling through the air toward the first soundboard means, and electromagnetic means mounted within the first soundboard means so as to vibrate the outer surface element thereof so that the first soundboard means generates sound waves induced by the electromagnetic means connected thereto comprising the steps of: (a) mounting at least one of the first soundboard means to at least one of the wall or ceiling elements so as to overlay a portion of the wall or ceiling elements within the audience listening area and remote from the sound source so that the outer surface element is oriented toward the audience listening area and away from the one wall or ceiling element; (b) positioning microphone means within the performance area to receive sound waves eminating from the sound source; (c) electrically connecting said microphone means to the electromagnetic means of the first soundboard means so that the electromagnetic means of the first soundboard means receives electrical impulses transmitted from said microphone means; and (d) amplifying the electric impulses transmitted from the microphone means to the electromagnetic means of the first soundboard means so that the first soundboard means is acted upon by vibrations generated by the electromagnetic means from electrical impulses received from said microphone means from the sound source while simultaneously being vibrated by sound waves received directly through the air from the sound source whereby the sound waves emitted from the first soundboard means is a combination of reflected and electrically generated sound waves
