Turbo compressors are, by nature, a loud noise source, typically 90 dB or more, and the major noise source originates from the impeller aerodynamic interaction with stationary components.
The robust SV104, which was entered by Svantek's North American distributor Sensidyne, was said to be recognised for being the world's most advanced instrument of its kind with features including: realtime octave band analysis that provides the data required for selection of personal hearing protection, three independent dosimeter profiles that allow the performance of multiple surveys at the same time, audio recording for peak or threshold noise source identification, a MEMS tri-axial vibration sensor that detects possible impacts and a durable MEMS microphone for greater shock resistance.
The researchers attempted to unravel this mystery by developing a theoretical basis for the owl's ability to mitigate sound from the trailing edge of its wing, which is typically an airfoil's dominant noise source.
We identified that the centrifugal compressor was the main noise source, with the maximum amplitude at 2912 Hz, during those operating conditions.
The microphone, located close to the noise source, captures the noise of internal fans, processes an anti-noise signal in the ANC digital signal processing (DSP)-based controller and transmits the anti-noise via the speaker.
The Quiet Lakes page features information on the noise caused by sport watercraft and what the NPC is doing to fight this noise source.
The total attenuation rose to more than 60 dB, so the next idea was "what happens if the noise source radiated its noise through open space?
The apparatus consisted of a white noise source connected to a tube shaped sample of the elastomer.
The most significant ultrasonic noise source was a laser process used to etch numbers on plastic tags.
Turbo compressors are, by nature, a loud noise source, typically 90dB or more, and the major noise source originates from the impeller aerodynamic interaction with stationary components.
It was then used to predict whether someone standing at a given location would be audible above a noise source at a third location - a proxy for ambient chatter.
