In order to improve the acoustic characteristics of the room and correspondingly improve the sharpness (e.g., warmth, richness and detail) of the sound generated by the source and perceived by the listener's ear located inside the room, Acoustic paint is applied to the walls of the room where the source of the source is located. The acoustic paint may be a powdered non-piezoelectric crystalline material having a resonant frequency to control the room acoustics according to the type of material and its resonant frequency by reacting the pulverized material to the sound generated inside the room, And a paint foundation in which the materials are mixed. An optional catalyst, such as powdered electrically conductive graphite or powdered graphene, is mixed into the paint foundation. The mixture is stirred and then applied to the walls of the room by means of a brush. |
