SYSTEM FOR STUDYING AND BUILDING IMAGES OF RESPIRATORY TRACTS NOISE Russian patent published in 2008 - IPC A61B5/08 

FIELD: medicine.

SUBSTANCE: system has a set of N transducers fixable above the chest so that i-th transducer is fixed in x_i position and produces P(x_i,t) signal inducing pressure waves in x_i position, where i=1...N. Processor calculates mean acoustic power P(x,t₁,t₂) on the basis of produced P(x_i,t) signals at least in single x position at the given time interval. P(x,t₁,t₂) value is determined using an algorithm related to at least single P(x_i,t) signal.

EFFECT: wide range of functional applications.
