The Science of Sound: How Sound Waves Reach Your Brain

The video explains sound waves, their travel through different mediums, and how they reach the brain. It details the process of sound entering the ear, causing the eardrum to vibrate, and how the brain interprets these vibrations as different sounds. The video also covers how the energy of sound waves affects their loudness, with louder sounds having more energy and exerting more force on the eardrum.

What mediums can sound waves travel through?

• Air, solids, and liquids

• Only liquids

• Only solids

• Only air

How does the ear contribute to hearing?

• It changes sound waves into light

• It blocks unwanted sounds

• It collects sound waves

• It amplifies sound waves

What happens when sound waves reach the eardrum?

• They disappear

• They are reflected back

• They make the eardrum vibrate

• They are absorbed

How does the brain differentiate between different sounds?

• By the color of the sound waves

• By the speed of the sound waves

• By the size of the sound waves

• By the vibrations of the eardrum

What determines the loudness of a sound?

• The color of the sound wave

• The direction of the sound wave

• The energy of the sound wave

• The length of the sound wave
