FIELD: physics. ^ SUBSTANCE: apparatus has a sound wave field source, e.g. a vibrating membrane with a corresponding magnetic system or a piezoelectric plate which is connected to a source of electric oscillations with controlled oscillation frequency. The sound wave field source is mounted inside a closed mechanical system which is in form of a rigid tube whose ends are closed by walls and is filled with a viscous liquid, where the sound wave field source is placed near one of said walls of the rigid tube, made in form of a convex reflector, and far from the other wall, made in form of a sound oscillation absorber. ^ EFFECT: possibility of confirming or refuting the hypothesis of power delivery to a sound wave field source. ^ 3 dwg |
