Abstract

Propeller propagated NOISE is very important for surface and submarine vessel. This phenomenon is non favorite for commercial and military ships. Originally, there are three sources for vessel NOISE, hydrodynamic hull, machinery and propeller NOISE. The propeller NOISE is higher than other two sources. In cavitation and non_cavitations, the propeller NOISE is different. In the article, Propeller Model B, the tunnel cavitation at different speeds (200 to 2000 RPM) and constant pressure to spin and propeller NOISE without the cavitation and the cavitation by Hydrvfn 8103 high sensitivity at a computer store and analyze its. According to the analysis carried out, increasing the impeller and flow water in the tunnel, increase the intensity of the propeller NOISE. The effective frequency band acoustic NOISE impeller in band audio systems and high intensity is a strong NOISE. The propeller NOISE SPL in octave band NO.15 is 72dB and in octave band No.18 is 75dB. In cavitation state the propeller NOISE in octave band NO.15 is 70dB and in octave band No.18 is 75dB.
