ABSTRACT:
The invention relates to a method to improve the acoustics of a room, preferably a hall, having a relatively minor space (10) from which sound waves, chiefly emanating from a musical instrument, and a relatively larger audience space (12), the outgoing sound waves being re-emitted via an amplifier device comprising a sounding board (20, 22) united with an electromagnet (26), an amplifier (21) and a microphone connected therewith, which device receives impulses from the sound source (14). The sound board (20, 22) and the electromagnet (26) form part of each of a plurality of wall elements (16) of such area and location in the audience space (12) that the sounding boards transmit to the listener a mixture of sound waves directly reflected from the sound source (14) and sound waves indirectly emanating from the amplifier device.
