Hardware vs Software Noise Cancellation: Which Should You Use?

· 2 min read

People mix these up all the time, then wonder why their expensive headphones did not fix their noisy calls. Hardware and software noise cancellation solve two different problems. Here is the difference in plain terms.

Hardware noise cancellation is for your ears​

Noise-cancelling headphones reduce the noise you hear. They use microphones to cancel out steady sounds like a plane engine or an air conditioner, so your listening is calmer. What they do not do is clean up the noise you send to a call. Your microphone still picks up your keyboard and your room.

Software noise cancellation is for your microphone​

Noise-cancellation software cleans the audio you send and, in some cases, the audio you receive on a call. It removes your keyboard, fan, and background chatter before they reach the other person. This is the piece that actually fixes noisy meetings.

So which do you need?​

  • Want quieter listening? Hardware, meaning noise-cancelling headphones.
  • Want to stop sending noise on calls? Software.
  • Want both a clean send and no echo? Use software for your mic, and wear headphones so your speakers do not feed back.

The two are complementary, not competing. Headphones make your side of the call calmer to sit through. Software makes you clearer to everyone else.

The practical setup​

For most people on a lot of calls, the best combination is simple: any decent pair of headphones plus real-time noise-cancellation software. The headphones handle echo and your own comfort, and the software handles what you broadcast.
