Description
ю щ и и с тем, что, с Целью упрощени процесса измерени , одиовременцо измер ют звуковое давление и колебательную скорость в произвольной точке ближнего пол , выдел ют из спектров сигналов не менее двух гармонических составл ющих, наход т фазовые соотнощени между давлением и колебательной скоростью на частотах этих составл ющих и по этим соотношени м определ ют тип акустического источника, причем, еслиHere, in order to simplify the measurement process, the sound pressure and vibrational speed at an arbitrary point of the near field are measured simultaneously, at least two harmonic components are extracted from the signal spectra, the phase relationship between pressure and oscillatory speed is found at the frequencies of these components and from these ratios the type of acoustic source is determined, and if
