Sound-magnifying appliances.-Resonance chambers are shown, applicable to the walls or floors of orchestras of theatres and of music and concert halls, platforms, pulpits, band-stands, and the like. A flooring of soft pine boarding E may be suspended over a brick and concrete pit A1 so as to form part of the floor of the stage or orchestra, and attached to it is a hemispherical or other-shaped metal trough G provided with soundposts H and tight strings J of steel, copper, or the like for the purpose of taking up vibrations. When suspended from a wall, the form is that of a box L with hard wood back, soft pine front, soundposts and strings. Each chamber has soundholes which may be formed in fancy panels and provided with closing flaps. Resonance chambers for the roofs of band-stands are described.
