Sound Vocabulary

auditory nerve

• carries electrical signals from cochlea to brain
• snail shaped part of inner ear that converts sound vibrations to electrical signals sent to the auditory nerve
• the part of the ear that amplifies the sound waves
• 3 tiny bones in the middle ear, that act as levers to increase vibrations

cochlea

• carries electrical signals from cochlea to brain
• snail shaped part of inner ear that converts sound vibrations to electrical signals sent to the auditory nerve
• the part of the ear that amplifies the sound waves
• 3 tiny bones in the middle ear, that act as levers to increase vibrations

ear canal

• snail shaped part of inner ear that converts sound vibrations to electrical signals sent to the auditory nerve
• carries electrical signals from cochlea to brain
• the part of the ear that amplifies the sound waves
• 3 tiny bones in the middle ear, that act as levers to increase vibrations

ear drum

• the part of the ear that amplifies the sound waves
• 3 tiny bones in the middle ear, that act as levers to increase vibrations
• carries electrical signals from cochlea to brain
• the sound waves from the ear canal cause the ear drum to vibrate

hammer, anvil, stirrup

• carries electrical signals from cochlea to brain
• the part of the ear that amplifies the sound waves
• the sound waves from the ear canal cause the ear drum to vibrate
• 3 tiny bones in the middle ear, that act as levers to increase vibrations

pinna

• carries electrical signals from cochlea to brain
• snail shaped part of inner ear that converts sound vibrations to electrical signals sent to the auditory nerve
• collects the sound waves and funnels them into the ear canal
• the part of the ear that amplifies the sound waves

decibel

• unit measuring frequency
• unit measuring loudness
• these vibrate when we talk to make sound
• the change in pitch (frequency) as a sound gets closer to you

Inner ear

• measures how high or low a sound is - determined by frequency
• measures how well a sound can be heard - determined by amplitude
• The Cochlea and the Semicircular Canals
• The Hammer, Anvil and Stirrup bones
