Different sounds can have different loudness levels because of a few important reasons:
Intensity and Amplitude: The intensity, or strength, of a sound is connected to its amplitude, which is how big the sound wave is. If the amplitude is larger, it means the sound has more energy, and it will be louder. In simple terms, a bigger wave equals a louder noise.
Frequency and How We Hear: Our ears hear different frequencies, or pitches, in unique ways. For example, we can hear mid-range frequencies (like a human voice) much better than very low or very high sounds. This is why you might not notice a high-pitched sound even if it's just as strong as another sound.
Sound Pressure Level: Finally, we use the decibel scale to measure how loud sounds are. This scale helps us understand loudness. A sound at 20 Hz might feel like it's booming more than we can actually hear it, while a sound at 2000 Hz can sound sharp and loud, even if it’s not super strong.
So, the way sounds work has to do with both science and how our ears pick up sounds!
