High pitch and Frequency are alike because they both are about sound. Also because they both describe sound. Low pitch and frequency are alike because they both help people hear and describe sound. Also they are alike because they both are tools.

Volume Definition of volume. How loud or soft something is.

Reflection and Echo. Reflection means sound bounces off an object ,or something bounces off a material. A sound wave does not act the same way when its hits a hard smooth surface. A sound hitting a towel will absorb sound but sound hitting a metal sheet it will reflect the sound wave. But not all sound waves reflect of some material. Some material that reflects sound waves are glass and plastic. A reflected sound wave is called an echo. If the echo is strong enough like in the grand canyon you will hear what you said. If there is more than one reflecting near you, you will hear it several times. The hard, smooth walls of your home are often great material for making echoes.
6
Absorption Absorption is when a sound wave disappears in a material. A good material for absorption is carpet. When a sound wave is absorbed the energy is changed into heat energy, when it is absorbed . Also a great place for absorption is a library. But not all echoes are absorbed by all materials.
