Final answer:
Loudness of sounds is dependent on the amplitude of the sound wave, measured in decibels (dB), with higher amplitudes leading to louder sounds.
Explanation:
Loudness of a sound is determined by the amplitude of the sound wave. Higher amplitudes result in louder sounds measured in decibels (dB). For example, a rock concert can reach around 120 dB, which is close to the pain threshold.
