At first glance “Sound” and “Noise” seem to mean the same thing. However, especially in producing Media they have very different meanings.

Sound refers to the audio that is intentional (such as Speech, music, sound effects), while noise refers to audio that is unintentional (EG wind in outdoor areas). This difference is related to “Listening” Vs “Hearing”: Listening refers to actively paying attention to a sound, and concentrating on it. Hearing refers to the sound registoring  in your ears, but not paying close attention.

For example, whilst in class we were listening to the teacher, but we could also hear the music playing outside. The difference being we actively focused our attention on what was being said, and could probably recall what had been said, while we were aware of the music, I personally wouldn’t have been able to say what the lyrics were even a few seconds after.
