Whether you are a podcaster, YouTuber, or just trying to record your voice for a video project, the ambient sound from anything around you can be picked up by your mic. This is why it’s important to choose the right type of mic for what you’re doing and how much money you want to spend on it. In this article, we will cover everything from ambient noise in microphones to solutions that will help save your recording if there is external noise in the background of your audio.
There are many common problems you can face when recording audio. If you feel your mic is picking everything in your environment, such as pc fan noise, body movements, chair noise, and so on, there are a couple of microphone background noise reduction solutions for this issue.
Which mic is more likely to be sensitive to ambient sounds?
There are two main types of microphones, dynamic and condenser. Dynamic mics are known for its ability to handle high levels of sound pressure. Condenser mics, while requiring a lower level of sound pressure to work properly, cannot handle high volumes as well as the dynamic mic. Dynamic microphones are less sensitive during audio recording and therefore easier to use for beginners. They will pick up the sound in front of them, unlike condenser mics, which means you can often record better without worrying about background noise spilling into your recordings.
As a result, condenser mics are more sensitive to sound than other types, and consumers should be aware of this. If you are using a cheap mic or gaming mic that is in close proximity to the speaker and has lots of ambient noise around it, you will also pick up more sounds generated from that direction.
All in all, as with any competing design, you have your pros and cons. Condenser mics provide a clearer recording while dynamic ones might be slightly muted or “muddy.” Again, it is best to choose what works for you based on the quality of your microphone.
You decide which type is better for you!

When it comes to reducing noise caused by wind or traffic in the distance when speaking, try setting up your
For more advanced users, it is widely known that izotope’s RX8 can be used to reduce background sound from your microphone. However, this comes at a price.
