METHOD OF SOUNDING FACILITIES Russian patent published in 2013 - IPC H04R5/02 G10K15/02 A61B8/00 

FIELD: physics.

SUBSTANCE: disclosed is a method of sounding facilities, which involves selecting spectral components of an electrical signal corresponding to different frequency bands, converting electrical signals into sound signals using loudspeakers mounted in parallel with given deviation of parallelism. The method also involves using a reflecting surface which is acoustically connected to the loudspeakers, tuning the system to establish in each loudspeaker - reflecting surface pair a standing wave at a frequency selected in accordance with external meteorological parameters and individual perceptibility, said frequency being determined by test listening with simultaneous measurement of human vital physiological parameters.

EFFECT: improved matching of standing waves in an acoustic system and a facility with frequencies of external field agents.
