How to Reduce Background Noise in Home Recordings: 7 Techniques That Work

1. Get Closer to the Microphone (Free)

Moving from 12 to 4 inches doubles the signal-to-noise ratio — often makes more difference than any equipment purchase.

2. Point the Mic Away from Noise Sources (Free)

Cardioid mics reject sound from behind — 15–20 dB at 180°. Position the rear toward computer fans, windows, or air vents.

3. Use a Dynamic Microphone Instead of Condenser

Dynamic mics are 10–20 dB less sensitive. The Shure SM58 ($99) or Rode PodMic ($99) will pick up dramatically less room noise than a Audio-Technica AT2020 condenser. See our dynamic vs condenser guide.

4. Use a Noise Gate (Free)

A noise gate silences your mic when not speaking. Every DAW and OBS Studio includes a free noise gate plugin. Set the threshold just above the noise floor.

5. Acoustic Treatment: Foam Panels (~$30)

A foam panel behind your mic and on the opposite wall reduces flutter echo by 50%+. Check the acoustic treatment category for products.

6. Cloudlifter or FetHead (~$99)

If your interface preamp is noisy at high gain, the Cloudlifter CL-1 adds +25 dB of clean gain. Essential for low-output dynamic mics like the Shure SM7B.

7. Post-Production: Noise Reduction Plugins

iZotope RX Elements (often $29 on sale) includes Voice De-noise. Always fix noise at the source first — plugins are the last resort.
