The one I found was the noise-cancellation module, which is one that dramatically lowers any static noise on the microphone and even A LOT of the background noise, basically giving you the benefit of only recording your own voice with excellent quality (For audio recording for example). To do this follow this steps: sudo nano /etc/pulse/default.pa
Multi-Channel Noise/Echo Reduction in PulseAudio on ...
https://pmeerw.net/pubs/Freiberger13a.pdf
Ambient noise and acoustic echo reduction are indis-pensable signal processing steps in a hands-free au-dio communication system. Taking the signals from multiple microphones into account can help to more e ectively reduce disturbing noise and echo. This paper outlines the design and implementation of a multi-channel noise reduction and echo cancellation
How To Enable Echo / Noise Cancellation Of Microphone ...
https://www.linuxuprising.com/2020/09/how-to-enable-echo-noise-cancellation.html
PulseAudio comes with a module that can be used to perform acoustic echo cancellation of the microphone input, and some background noise reduction. This module is not enabled by default on most (if not all) Linux distributions, so this article will show you how to enable it. I'll show you 2 ways of enabling the PulseAudio Echo Cancel module: one that makes …

PULSE_PROP="filter.want=echo-cancel" before application name. So for Skype the command will be: PULSE_PROP="filter.want=echo-cancel" skype Before and after. METHOD 2. You can add this to /etc/pulse/default.pa: load-module module-echo-cancel Or this for a better noise cancellation method - WebRTC: load-module module-echo-cancel aec_method=webrtc
Impulse noise reduction in audio signal through multi ...
https://www.sciencedirect.com/science/article/pii/S2215098618313211
Audio signal is often corrupted with different types of noise, among them are Gaussian noise, impulse noise, and others. Gaussian noise is the worst noise corrupts every sample in the audio signal. Consequently, many researchers spent great effort to remove such noise. The other important noise that may corrupt the audio signal is the impulse ...

Acoustic noise control resulted in an average reduction of 12.5 dB (A) which equals. a reduction of the average acoustic noise level of 74% (range: 56% - 90%) for the A-. …
Pulse - Reducing Noise Levels - IQIP - IHC IQIP
https://www.ihciqip.com/en/products/piling-equipment/pulse
Pulse, IQIP’s latest innovation, reduces the noise level significantly during pile driving operations and ensures an environmental friendly installation. The system, which is an add-on to standard hammer such as the Hydrohammer, is positioned between pile driving hammer and sleeve and dampens the impact and noise with two hydraulic plungers.

Download PulseAudio Distribution. Typically PulseAudio would be provided by your OS distribution. As PulseAudio forms part of what is typically preferred to as the plumbing layer of Linux userspace, it is a non-trivial job to integrate it fully to form a complete system. This is why we strongly encourage you to go via your distribution whenever possible.
Reducing noise on the output of a switching regulator

reject a certain amount of noise coming from that power rail. At higher frequencies, this PSRR value decreases, allowing the HF noise to couple through more easily. That’s potentially 20 mVpp of noise getting into the signal chain. This is where it becomes critical to take a close look at choosing the inductor. To account for high-frequency
