In Summary: How to Reduce Background Noise in a Video?
Check out this straightforward way of how to reduce background noise in a video:
- Choose a quiet location: Choose a location with minimal background noise when recording.
- Use a Quality Microphone: Invest in a good microphone that reduces unwanted sounds.
- Utilize Editing Software: Use editing software with noise reduction features, like Premiere Pro or CapCut, to clean up audio.
- Conduct Test Recordings: Always conduct a test recording before the main recording to identify and address background noise issues.
- Fine-tune Settings: Fine-tune sensitivity and frequency settings during editing to balance noise removal and audio quality.

Understanding the Sources of Background Noise in Recording a Video
Background noise can make your audio sound unclear. To handle it better and learn how to reduce background noise on the mic, it’s important to understand what causes unwanted noise.
1. Microphone Range
Each of the best streaming microphones has a set range that affects how well it picks up sound. Anything within this range, including unwanted background noise, will be captured.
2. Faulty Microphones
A damaged microphone can introduce extra noise, like static or buzzing, affecting the clarity of your recording.
3. Microphone Types
All types of microphones, including those on laptops, smartphones, and cameras, are prone to picking up background noise.
4. Hidden Background Noise
Some background noises, like low-frequency hums, may not be immediately audible but can show up during playback.
How to Reduce Background Noise from Microphone? Effective Strategies
Background noise can significantly impact the quality of your recordings, often overshadowing the desired sound. This is why it is extremely important to understand how to reduce background noise from a microphone. Here’s how you can do it:
Strategy #1: Adjusting Gain Levels
The gain in a microphone refers to the amount by which the input signal is amplified. It increases the microphone's sensitivity, allowing quieter sounds to be captured more clearly by boosting the signal level. This can be controlled either by a knob on the microphone or through software.
However, adjusting the gain too high can lead to distortion and unwanted noise, while setting it too low may result in weak or inaudible audio. Proper gain settings are essential for maintaining audio clarity and balance.
Therefore, one needs to have substantial knowledge of managing the microphone's gain. Although some unwanted gain can be adjusted in post-production, having it tuned to the right amount with respect to the recording environment is mandatory.
Strategy #2: Using Noise Suppression Filters
A suppression filter is a software component used to remove undesired background noise. They come in various types that includes:
- High-pass filters: Remove low-frequency sounds (below a certain cutoff frequency), such as rumble or handling noise.
- Low-pass filters: Eliminate high-frequency sounds (above a certain cutoff frequency), such as hiss or high-frequency noise.
- Notch filters: Target and reduce specific frequencies, often used to eliminate feedback or hum.
How to Reduce Background Noise on iPhone?
These days, more people are using iPhones to record videos instead of professional cameras because they are simple and easy to use. The iPhone’s camera and microphone are optimized with advanced hardware and software, offering a convenient point-and-shoot experience. Here’s how to reduce background noise on an iPhone.
Using iMovie for Noise Reduction on iPhone
iMovie is one of the most recommended video editing solutions in the Apple ecosystem. It includes effective built-in audio filters that are useful for noise removal while also having a user-friendly interface.
- Import the unedited video into the application from your media folder.
- After the file is imported, reach out to the effects tab, and go for Audio Filters.
- Opt for the noise reduction tool, and use the slider available to tune the amount of background noise.
- It also features an equalizer, which can be used to remove unwanted background frequencies, especially when tuned by a professional.
- During post-processing, you can conduct a listening trial using quality headphones (preferably ones with noise cancellation) to verify whether your noise removal techniques have been effective.
- Once edited, you can save the video.
