Background noise refers to the ambient sounds that are present in an environment but are not the main focus of attention. This can include sounds like traffic, conversations, or music playing in the background. While these sounds may not be the primary focus, they can influence how we perceive other sounds and can affect our concentration and mood. In various settings, such as offices or homes, background noise can either enhance or hinder productivity. For example, some people find that a moderate level of background noise helps them concentrate, while others may find it distracting. Understanding background noise is important for creating environments that support effective communication and focus.
