Noise canceling architecture in 30 presents an approach to alleviate Circuit Diagram 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.
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?

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 In an attempt to make a DIY Noise Cancelling, The only challenging factor in making a noise cancelling headphone is acoustics and making sure that the inverted sound wave is still in phase.

Noise Cancellation with Op 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. When any noise enters into the headphones or earphones the processors which are present in it make the signal which is equal in magnitude but opposite in phase. Thus the signal which is generated by processors is added with the actual noise signal due to which their addition almost becomes zero and you can just listen the music very clearly as compared with the headphones of other companies (I
