Cochlea
Decibel
Unit of measurement that indicates relative intensity of a sound (dB)
What is a safe range decibel amount
0-70dB
🐟FISH🐟
The number of vibrations per second the ear receives
Frequency
True or false, All sound waves have the same amount of energy
False
Sound intensity
Measurement of how much sound energy passes through a certain area in a certain amount of time as it spreads out.
At what decile is the noise source risky?
80db
A graph that shows the sensitivity of a person's hearing for various frequencies
Audiogram
Two characteristics that all waves share
Frequency and speed
Hertz
How we measure a waves frequency
Some explosions
What are Compressions
Regions of high air pressure
Transfers energy through compressions and rarefactions in the material through which the energy travels
Longitudinal Wave
Speed of sound formula
Speed=distance/time
Name a Noise Source at 130db
Threshold of pain
Wave
disturbance that repeats regularly in space and time
When the wavelength decreases, what does the frequency do
Increase
Rarefraction
Regions of low air pressure, spread out
