Wide area noise cancellation system and method Circuit Diagram Project Overview Using the simple electronics system illustrated in Figure 1, you will get to experience volume reduction through destructive interference, which forms the basis of noise-canceling headphones. Figure 1. Noise cancellation project illustration. In one operating mode, the sound waves will reinforce one another to increase the volume. Analog Noise Cancelling Headphones: Noise cancelling headphones are an ideal choice for many music listeners for their ability to cut out ambient noise without raising the audio volume to levels that might be dangerous for the ear. Even with no music playing, the headphones have the aโฆ how to make noise cancelling mic - Microphone and microphone headset Not Pick Up Background Noise - Noise circuit remove Background Noise Mic: use capacitors and resistors Prestigious and useful
Active noise cancellation uses carefully located microphones, signal digitization, and sophisticated, adaptive algorithms to create inverted signals to cancel out offending audio-band noise while leaving the desired sound unchanged, resulting in a quiet background and better listening (or resting) experience.

I am trying to make an audio amplfier using an opamp for a project. It works kind of okay but the only issue is there seems to be a lot of noise in the output of a 0.5 watt speaker. I have tried changing the various capacitor values but there still seems to be noise. Whts the best way to bring down this noise in the circuit?
The audio noise limiter circuit presented here limits noise peaks. It can be used with AM short-wave (SW) receivers and amateur radio (HAM) transceivers. Project: Active Noise-Cancelling Circuit Table of Contents Equipment Overview Pre-amplfier Delay Summing amplifier Power supply Speaker Headphones Using your new knowledge of how sound works and with a basic understanding of circuitry and electronics, you can construct an active noise-cancelling circuit (ANC)! This circuit can also be attached to headphone jacks to attach it to your heaphones
