What is sound
What is volume?
How loud a sound is/amplitude.
What is a crest, and what is a trough?
The highs and lows of a wave.
What is volume measured in?
Decibels.
What is speed?
How fast the wave is.
What is a medium?
A solid, liquid, or gas.
What is pitch?
How high, or low a sound is/frequency.
What is wave length?
The measurement of crest to crest, or trough to trough.
How loud is someone talking
About 60Db.
What role does amplitude do in calculated speed?
Nothing. It does nothing.
What is a sound wave?
A stimuli that travels through a medium.
What is Hertz?
The measurement of speed.
What is amplitude?
The height of the top of the crest, to the rest position.
What are options that you can do when the volume is too loud?
Turn down the volume, walk away, or prevent the volume from entering your ears.
How do you measure speed?
In hertz.
What is a source and a reciever?
The source of a sound, and the thing that recieves the sound.
How does sound travel?
From the source of disturbance, outwards. It disperses its energy with the air.
What is frequency?
The amount of time a wave passes a spot in a second.
How loud is a vacuum cleaner?
Around 75Db to 85Db.
How do you calculate speed?
Speed = Frequency x Wave length
What is a signal?
A current sent to your brain.
How do you hear sound?
What's the difference between a Sine Wave Model, and the rest position?
A Sine Wave Model is a model of an active wave, while the rest position is of an unactive wave.
How loud does it have to be to damage your hearing instantly?
Above 120Db.
If the frequency is 7 and the wavelenght is 4.5, what is the speed?
7 x 4.5 = 31.5Hz
What are some ways a wave can interact with a medium?
Reflect, transmit, and absorb.
