How to Remove Background Noise from Video?

In this digital age, video calls have quietly become an integral part of our daily lives and work. However, annoying background noise often ruins the call experience, making the originally pleasant communication frustrating. This article will reveal the causes of background noise for you and provide practical solutions for how to remove background noise from video, so you can enjoy clear and smooth video calls anytime, anywhere.

What Causes Background Noise in Videos?

To solve the background noise problem, we first need to understand its sources. Background noise often comes from two main sources: environmental and technical. Let's take a closer look at them.

Environmental factors

1. Ambient noise in the surrounding area. This includes the sound of cars on the street and people talking to each other. The noise of children playing downstairs is also often a distraction. These everyday sounds can be especially noticeable in video calls.
2. Home noise. The app's sounds running in the home are often ignored. The refrigerator hum and the washing machine whirring are common distractions. Don't forget the occasional barking of pets, which may also appear suddenly during a call.
3. Workplace noise. There are many sources of noise in the office environment. The sound of keyboards and printers is common. The discussion between colleagues is an inevitable background sound.

Technical factors

1. Equipment quality. Poor-quality microphones are a big problem. They may pick up too much ambient sound. This can cause your voice to be drowned out by background noise.
2. Microphone position. The position of the microphone is crucial. Improper placement may cause it to pick up more ambient sound. This can make your voice unclear.
3. Network quality. Unstable network connection is also a common problem. It can cause the sound to freeze or become distorted. This can seriously affect the quality and fluency of the call.

By knowing the noise source, we can take more targeted measures. This can greatly improve the video calls audio quality. Remember, identifying the problem is key before solving it.
