This work proposes a noise-reduction structure that integrates phase-modulating metasurface (PMM) with acoustic liners (ALs) to enhance the narrow band absorption performance of a duct with relatively small length-diameter ratio. The PMM manipulates the
The calculation results show that the output of the trained ANNs has the significant correlation with the averaged subjective rating of sounds. It is concluded that the output vector of the ANNs can objectively estimate the rate of noise sound. Eq. (24) can be used as a design guide for ...
The slew rate reduction capacitor shown above is in addition to the components of your application, of course. It is no way negates the requirement to close the loop of the op amp, I merely omitted all other components to show the addition of one part. It is also good to keep this ca...
The Sigma-Delta technology proves to be the most suitable choice when compared with the faster but less precise counterpart of the SAR type since the sampling process used by the first operates on an oversampling principle even 100 times higher than the sampling rate set. Observations of this ...
There are two main directions of noise reduction techniques: acquisition-based signal increase and post-acquisition noise reduction during or after reconstruction. During image acquisition, an improvement of the SNR can either be achieved by averaging over repeated measurements and, thus, extending the ...
The noise of op amps is Gaussian with constant spectral density (white noise), over a wide range of frequencies. As frequency decreases, the spectral density starts to rise because of the fabrication process, the IC device layout, and the device type at a rate of about 3 dB per octave fo...
These require intelligent noise reduction processing through AI algorithms. AI noise reduction can identify the instantaneous noise that needs to be filtered out through model training. In theRongyun RTC Advanced Practical Master Class on June 9, the Rongyunaudio algorithm engineer fully shared the AI...
The past trends in aircraft noise reduction have shown a steady rate of decline, obtained through the conventional circle of research and development, as briefly introduced in Section 2. However, it is clear that the ‘asymptotic’ improvements in noise performance adopted by industry at the moment...
