Sound intensity and loudness are closely connected, even though they sound a bit different. Let's break it down simply:
Sound Intensity: This is about how strong sound is. It’s measured in watts per square meter (W/m²). This tells us how much energy the sound has.
Amplitude: Think of this as how "big" the sound wave is. If the amplitude is bigger, the intensity is higher, which means the sound is louder.
Perceived Loudness: Here’s something interesting! Our ears don’t hear sound intensity in a straight line. Instead, it works in a different way called logarithmic. For example, if the sound intensity goes up by ten times, we hear it as only about twice as loud!
In short, when sound intensity is higher, it usually sounds louder. But how our ears understand it can be surprising!
