What is the definition of Reserves Sounds?

Reserves sounds are like the unexpected creaks and groans of a forgotten, possibly haunted, childhood toy box. They're the whispers of the past that make your brain go "What was that?" and your heart race with curiosity. But fear not, these sounds usually just mean the old wooden slats are settling down or maybe someone was really messing with the furniture before you.
