Title (EN) ACOUSTIC PAINT
(FR) PEINTURE ACOUSTIQUE
Abstract:
(EN)An acoustic paint to be applied to the walls of a room in which a source of audible sound is located to improve the acoustic characteristics of the room and correspondingly Improve the clarity (e.g., the warmth, richness and detail) of the sound that is generated by the source and detected by the ear of a listener located within the room. The acoustic paint includes a paint foundation into which is mixed a powdered piezoelectric material or a powdered non-piezoelectric crystalline material having a resonant frequency so that the powdered material will react to the sound generated within the room and thereby control the room acoustics depending upon the type of material and the resonant frequency thereof. An optional catalyst, such as an electrically conductive powdered 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.
ACOUSTIC PAINT

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

This invention relates to an acoustic paint that can be applied to the walls of a room to improve the audible clarity of sound generated within the room and heard by a listener. The acoustic paint includes a powdered piezoelectric or non-piezoelectric crystalline material having a resonant frequency which reacts to the sound to control the acoustics within the room.

[0002] 2. Background Art

A listener may find himself located within a room while listening to music or other audio content. In many cases, the sound is emitted from a speaker and transmitted unidirectional ly to the listener. That is to say. the listener may not know that he is surrounded by sound or that the sound is coming to him from different directions. Moreover, the sound can be absorbed or distorted by the walls of the room, such that the audible clarity of the sound is negatively impacted.

[0003] Therefore, it would be desirable to have an innocuous and aesthetically pleasing treatment to cover some or all of the walls of the room by which to control the acoustics in the room and improve the audible clarity (e.g., the warmth, richness and detail) of the sound heard by the listener whether or not speakers are used. In this same regard, it would also be desirable for the sound to appear to the listener to be more realistic (i.e., live) and coming to him from different directions within the room in which he is located.
