Description
  • The result is a computing program ( program SPAD ), which is intended for fast analysis of the noise of propeller driven airplanes. The program works on the principle of spectral decomposition. It computes continuously high-resolution discrete short-time spectra of the analyzed noise, traces the periodic noise components in the spectra, and separates them from the rest noise. Then it evaluates independently the separated periodic noise components produced by the propeller ( or propellers ) and the rest noise, without the propeller noise components. Its adjunct procedures make possible to back-transform or re-synthesize the separated noise components.

  • Výsledkem je výpočetní program ( SPAD ) určený rychlou analýzu hluku turbovrtulových letadel. Program pracuje na principu spektrální dekompozice. Počítá průběžně diskrétní spektra analyzovaného signálu s vysokým rozlišením, vyhledává a sleduje periodické komponenty a separuje. Dále pak vyhodnocuje samostatně periodické složky hluku generované vrtulemi a zbytkový hluk bez vrtulových složek. Doplňkové procedury umožňují dále zpětnou transformaci nebo syntézu separovaných hlukových složek (cs)
