Loudness and pitch
In this Class 9 Science topic from “Sound Waves: Characteristics and Applications,” students learn how loudness and pitch describe different characteristics of sound. They explore how loudness is related mainly to the amplitude of vibrations, while pitch depends on the frequency of vibration. The topic helps distinguish loud and soft sounds from high- and low-pitched sounds, introduces common units such as decibel and hertz, and connects these ideas with musical instruments, speech, and everyday sound experiences.
