What is background noise?
Background noise, also known as ambient noise is any sound that is not the primary source of the sound you are recording.
This can come in the form of all sorts of noise depending on where you are filming. For instance, outside you may pick up additional noise like wind or traffic. Whereas inside your microphone may pick up background noise from alarms, fridges, or cookers.
To prevent background noise, the first port of call is sound control. Make sure you can clear any potential cause of background noise before you begin filming. Also, make sure you have the correct microphone set up to enable you to pick up your primary sound.
