If parents know about the different types of sounds, it will help them understand how much and what kind of sounds their children can hear.
Some sounds are louder than others. Noises that are closer are louder than the same noises farther away.
Some sounds can be made louder or quieter. For example, you can increase the loudness of a radio or you can make your voice quieter by changing from a shout to a whisper.
Pitch is how high or low the tone of a sound is. Like in music, sounds can go up and down from
high to low pitch.
|a bird||a flute||water pouring||a baby's cry||Higher-pitch sounds have a sharp, thin sound that can feel like it goes right through your ears.|
|a cow||a drum||thunder||a man's voice||Lower-pitch sounds have a full, heavy sound that you can feel in your bones.|
Different speech sounds also have higher or lower pitches. For example, the sounds 'o-o-o' and 'm-m-m' have a low pitch. The sound 'e-e-e' has a medium pitch. The sounds 's-s-s' and 'f-f-f' have a high pitch.
