DIY Noise Cancelling With 741 Inverting OP-AMP
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. This video demonstrates (in someways) Inverting the sound with minimal delay for canceling is possible with 741 op amp. Also check out my Instructable page ...
