Animal Sound Flashcards
How do sound waves travel
Through air eg when u speak your vocal cords vibrate to Purdue sound waves and they travel through the air to the other person ear
What’s the intensity
How loud or soft
Pitch
How low or high
Different parts of a sound wave
Amplitude if is is big it means it’s a low amplitude
Wave length if it is sorter it means it has a high frequency
How do scientist analyse sound
Oscilloscope
Microphone
What does
Transferred mean
When energy is passed from one thing to another
Vacume
An empty space
How we hear
Sound vibrations approach the ear
Vibrations in ear pass to ear drum
Vibration in ear drum pass to bones in middle ear
Vibrations in the middle ear pass to the cochlea
Cochlea converts sound energy to electrical energy
This energy travels to brain along the auditory nerve and sound is heard
Ear damage
If something is to loud
If ear wax get stuck
Loud bangs
Age
How is sound reflected
The wave bounces off the object and caused an echo
How can sound be absorbed
Sound waves that don’t get reflected by a material and don’t pass through it are then absorbed
Sound proof
Materials that are good absorbers of sound don’t pass on vibrations to other partials
Noise
An unwanted sound
How is sound intensity measured
Sound intensity meter
How are sound waves produced
By vibrating objects
