volume - how powerful the sound wave is which tells us how loud or quiet it is , vibration - invisible waves that move quickly , sound wave - invisible waves that travel though a medium like the air from one place to another, loud - a word used to describe a sound made by strong vibrations or a greater amplitude , quiet  - a word used to describe a sound made by weak vibrations or shorter amplitude , high pitch - a sound wave with a short wavelength and a high frequency (Example: A mouse squeaking), low pitch - a sound wave with a long wavelength and a low frequency (Example: A lion's roar), tone - a musical or vocal sound with reference to its pitch, source - where something comes from, sound - vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear., amplitude - a measure of the strength of the sound wave (how loud or quiet it is), frequency - a measure of how many times per second the sound wave cycles , ear drum - the membrane of the middle ear, which vibrates in response to sound waves, ear canal  - functions as an entryway for sound waves, pitch - how high or low a sound is, decibels - a measure of how loud something is, medium - something which transfers energy from one place to another. Air is a medium that can transfer sound., wave length - the length of one complete sound wave cycle, transmit - to pass from one place to another, ear bones - the three tiny bones in the middle ear of all mammals. Together they form a short chain that crosses the middle ear and transmits vibrations caused by sound waves from the eardrum membrane to the liquid of the inner ear, cochlea - the spiral space of the inner ear, which produces nerve impulses in response to sound vibrations,
