| Therefore, air pumping has a direct influence on noise. | |
01 Jan 2008 10 Citations | The present research was suggested by the observation that some peaks in the airborne noise spectrum of a specific pump family were within a frequency range far from those typically related with the fluidborne or structureborne noise; unfortunately, in that range the human ear does not filter the noise efficiently. |
| We found that two methods were effective for reducing the pump noise. | |
34 Citations | We find that two noise sources are mainly responsible for the observed behavior, fundamental thermal noise at low pump power levels and temperature fluctuations induced by pump intensity noise at higher powers. |
19 Citations | A real-time frequency analizer allows monoaxial intensimetry analysis of airborne noise while, elaborating on the instantaneous pressure ripple at pump delivery, fluid borne noise is also detected; both informations being of prime relevance as part of a pump design and development programme. |
1 Citations | Through the experiments, the exciting force compensation has been verified to be effective for noise reduction of a pump. |
45 Citations | Noise from internal sources, such as air-conditioning systems, may also be important. |
17 Citations | A remarkable increase of the noise level with decreasing frequency is observed below ≈35 kHz, probably due to technical noise of the amplifier pump diodes. |
| Improvement in the pump performance at higher degrees of air input mass flow rates is expected when employing multistage air injection. |
