Introduction
Whether you’re recording a podcast, a video or just trying to make a phone call, there’s nothing worse than background noise. Whether it’s the sound of traffic, construction work or even just the hum of your air conditioner, background noise can ruin an otherwise perfect recording.
Fortunately, there are a number of ways to reduce or even eliminate background noise from your audio recordings. Here are just a few of the most effective:
Use noise-cancelling headphones
One of the simplest and most effective ways to reduce background noise is to use a pair of noise-cancelling headphones. These headphones use microphones to pick up on ambient noise and then generate a sound wave that cancels out the noise. This can be extremely effective at reducing everything from traffic noise to the sound of your own breath.
Move your microphone closer to your mouth
Another simple way to reduce background noise is to make sure your microphone is as close to your mouth as possible. The further away your microphone is from your mouth, the more likely it is to pick up on ambient noise. So, if you’re recording audio for a podcast or video, be sure to position your microphone as close to your mouth as possible.
Use acoustic panels
Acoustic panels are designed to absorb sound waves, which can help reduce the amount of ambient noise in a room. If you’re recording audio in a studio or office, placing acoustic panels around the room can make a big difference in the quality of your recordings.
Use software to remove background noise
If you’re struggling to remove background noise using the methods above, there’s no need to worry – there’s still hope! There are now several software programs available that can help remove background noise from audio recordings automatically. All you need is a decent computer and a good quality microphone, and you’ll be able to produce crystal clear recordings with ease!
What Causes Background Noise?
Some sounds are just part of the environment, like traffic noise from a busy street. But others are caused by electrical interference, like humming from a power line or transformer. Background noise can also come from your phone line or cellphone connection.
In an office, cubicle panels and walls can act as sound barriers, but they can also create their own problems. Poorly designed office spaces can cause echoing and reverberation, which amplifies background noise and makes it more difficult to concentrate.

How to Remove Background Noise from Audio With Hardware
If you want to remove background noise from your audio, the most straightforward way is to use hardware that’s designed for that purpose. Dedicated noise-cancelling hardware can be expensive, but if you have a limited budget, there are some cheaper alternatives that can still be effective.
One option is to use a microphone with a built-in noise-cancelling feature. These microphones are designed to reduce or eliminate ambient noise, and they can be very effective in reducing background noise in your recordings.
Another option is to use a USB audio interface with a software plugin that provides noise cancellation. There are several different plugins available, and they can vary in terms of effectiveness and price.
If you have the budget for it, dedicated hardware is always going to be the best option for removing background noise. But if you’re on a tight budget, there are still some effective ways to reduce or eliminate ambient noise in your recordings.
How to Prevent Background Noise
In order to prevent background noise from becoming a distraction or nuisance, you’ll need to take some steps to reduce or block it out. Here are a few suggestions:
- Wear headphones: Invest in a good pair of headphones or earbuds that will help block out external noise.
- Listen to white noise: There are many apps and websites that offer white noise or nature sounds that can help mask background noise.
- Create a soundproof space: If you work from home or have your own office, consider soundproofing it with insulation, carpets, or acoustic panels.
- Use noise-cancelling technology: Some devices come with built-in noise-cancelling features or you can buy standalone products like earplugs or Noise-Cancelling Headphones.

In conclusion, there are a few different ways that you can remove background noise from your audio recordings. You can use an external microphone to isolate the sound, use Audacity to reduce the noise, or use a professional studio to edit the recording.
