<p>The present invention relates to an apparatus for filtering sound, in which a filter panel is suspended by elastic members and filters sound waves from a sound source to correct distorted wave forms by making compressions and rarefactions of the sound waves uniform using the elastic force due to compression and expansion of the elastic members while the sound waves hit the filter panel. According to the invention, the audience can hear soft clear sound close to the original sound while listening to music or seeing a performance, even in a room equipped with a variety of structures that distort sound. Therefore, the invention is particularly useful for specialized-performance buildings having performance halls or theaters.</p> |
