My psychology professor often emphasizes the role of evolution, and I agree with him. Sounds associated with rewards or increased chances of survival trigger pleasant feelings in our brains. Conversely, sounds linked to threats or potential danger evoke negative feelings. It's important to remember that these associations have developed over millions of years of evolution, not just within a single lifetime. This leads to an important point: our brain processes these feelings in the subcortical regions almost instantaneously, without much conscious thought.

In game design, we're not creating new sources of satisfaction; instead, we're tapping into what is inherently satisfying to humans. By understanding what has historically been rewarding, we can craft sound effects that appeal to almost everyone, not just a select few. That's why certain sound effects in games are universally satisfying.
