A dolphin first recieves incoming sound waves through its jaw then

• from human to human in the air.

• Sound waves travel faster from dolphin to dolphin underwater than

• it goes to its inner ear and finally the nerve impules are sent to the brain

• In digital technology, patterns create code

Sound waves travel faster from dolphin to dolphin underwater than

• If the highest sound people can hear have frequencies of about 20,000 vibrations per second and dogs can hear higher frequencies than humans can hear then you see a dog trainer put a whistle in his mouth and blow, but you don’t hear anything. Then a dog comes running. What can you infer about the whistle?

• In digital technology, patterns create code

• from human to human in the air.

• that sending devices and receiving device can understand.

• use electrical signals to send communication over long distances.

• The sound the animal makes is below the range of human hearing.

Why can cats hear mice sometimes and humans can not?

• The sound the animal makes is below the range of human hearing.

• to find and eat prey

• What is a likely reason cats have advanced hearing?

• The sounds will become quieter

What is a likely reason cats have advanced hearing?

• to find and eat prey

• The sounds will become quieter

• The objects absorb the sound vibrations that reach them.

If a room is filled with soft objects what will happen to the sound in that room?

• Be able to explain waveforms, wavelengths, amplitude, volume, and pitch in relation to the sound an animal makes.

• The sounds will become quieter

• The objects absorb the sound vibrations that reach them.

• to locate objects that are smaller in size. This is different than how humans use it.
