When a new scene is created in Unity, a Main Camera object is created as well, and included in the scene. This camera is responsible, by default, for displaying the actual game scene when we press the Play button in the Unity Editor. Among the components the camera comes attached with by default, there is a component named Audio Listener (you can check it out in the Inspector panel). This component allows sounds to be heard by the player through the built-in speakers of their device or through a headset.
