Sounds refer to vibrations in the air that are detected by our ears and interpreted by our brains as auditory sensations. They can be produced by various sources, such as voices, music, or environmental noises.
Sound waves are the physical vibrations that travel through the air or other mediums when producing sound. They consist of compressions and rarefactions, similar to how a slinky toy moves back and forth.
Pitch refers to how high or low a sound is perceived to be. It is determined by the frequency of sound waves, just like different keys on a piano produce different pitches.
Amplitude represents the intensity or loudness of a sound. It corresponds to the height of sound waves, similar to how turning up the volume dial on a stereo increases its amplitude.
