Definition: A medicine or other agent to assist hearing.

Alright class, settle down, let’s take a look! That dictionary definition – “a medicine or other agent to assist hearing” – is a good starting point, but it needs a little tweaking. Let's think about sound for a moment. “Acoustic,” you see, isn’t just about medicine. It’s got a deeper meaning, a musical decree! It comes from the Greek word “akousis,” which means "to hear." But it's evolved to describe something related to how we experience sound itself. Think of it like this: Acoustic music – that’s music played without lots of electronic effects, relying on the natural sounds of instruments and voices. It’s pure and clear, you see! An acoustic room – one where sound travels freely, bouncing off walls and ceilings in a natural way, so it doesn't feel muffled or boxed in, glee! Essentially, "acoustic" describes anything connected to the quality of sound - whether it’s the source, the space, or even a technique used to capture or reproduce it. Does that make sense? Do you have any questions about how "acoustic" is used beyond just helping someone hear better?
