Sažetak
Investigation and comparison of aircraft interior noise is presented for different aircraft propulsion systems. Interior noise of four airplanes (piston, turboprop, turbojet and turbofan) and two helicopters (piston and turbine) is analyzed. Spectral and temporal properties of interior noise are given with reference to aircraft flight phase using flight simulator sound generator with recorded interior noise. A mathematical description of interior noise spectrum related to engine, propeller and rotor rotation speed and noise of relative wind is presented. Based on the analyzed interior noise properties proposals for suitable noise reduction methods are given.
