Why Video Background Noise Happens

Why does background noise in video occur in the first place? This issue is not just a random annoyance; it is the result of how the sound waves interact with your environment. Knowing the reasons behind the distorted audio is the first step to remove unwanted background noise from video.

• Poor microphone placement. If your microphone is placed too far from you, it will be hard for it to pick up your voice.
• Low-quality mic hardware. Entry-level mics often have a self-noise floor, delivering a constant electronic hiss in every recording.
• Environmental noise. Sounds like traffic, air conditioners, or echoes create a layer of room tone that clashes with your main audio.
• Automatic gain control (AGC). Many cameras automatically adjust volume during silence, which turns the quieter background static into a loud hiss.
• Compression and recording settings. Low-bitrate settings can deliver digital artifacts, making background noise sound distorted, reducing overall audio clarity.
