I learned that elephants can hear lower pitched sounds that most animals can not. I also learned that this is the most common the way that elephants can communicate.
I discovered the meaning of infrasonic, supersonic and ultrasonic via Google.
Demonstration of the word infrasonic in a sentence: Some animals can here infrasonic noise waves and can evacuate areas hours before a tsunamis occurs.

I learn today during our Reading on "Silent Sound" ( I can't remember the title exactly ) That once again, as Camden stated, elephants can hear lower frequencies than us human. Also, on the definitions, I will state my thoughts then look up the definition of : Supersonic. Ultrasonic, and Infrasonic. TO ME ( In caps so you can notice it ) Supersonic means that it is traveling at very high speeds, Ultrasonic is the same but faster, and Infrasonic is like Infrared, it is very high and can only be heard by very high animals and radio waves ( For example : Dogs and Bats. WHY NOT HUMANS?!??!?! ). OFF TO GOOGLE!!!!!!!!
Definition : Ultrasonic is higher waves that humans cannot hear (20,000 Hertz and above, ), and Supersonic is traveling faster that the speed of sound, and Infrasonic is lower that the hearing range ( 20 Hertz and below ).
I was semi-right?
OFF TO WATCH YOUTUBE!
I just re-read the instructions. Sentence(s):
Infrasonic : Elephants can hear Infrasonic sounds, but humans can't.
Ultrasonic : Dogs can hear Ultrasonic sounds
Supersonic : An example of a supersonic thing is light, faster than sound!

The ultrasonic meaning is sound waves with a frequency above the limit of human hearing. how I got the definition Siri. my sentence "when a dog is barking a ultrasonic sound blasts out that only a dog can hear because the sound is above the limit of human hearing.
Infrasonic means sound waves with a frequency below the limit of human hearing. I got the definition from Siri. Animals such as frogs, snakes, ants, and fishes can hear infrasonic sounds.
supersonic meaning is speed that is greater than sound. I got that from siri. Elephants use supersonic sounds when traveling to signal their herd that are far away to move with them.
In ''Silent Noise'' I learned that elephants pick up frequencies too low for humans to hear. I discovered the definition of supersonic, ultrasonic and infrasonic from Feedback Google.
The elephants supersonic noise hurt my ears.
We leared that elephants comunicate with lower pitched sounds, which also travel farther. Humans cant pick up these sounds because our ears are not senseitive enough. We also learned that other animals can pick up diffrent sounds, some higher than others. We as humans can only 20 to 20,000 Hz, as a dog can hear 67 to 45,000.
Sentence: We could not hear the supersonic sounds.
Def, Supersonic: nvolving or denoting a speed greater than that of sound.
Def, Ultrasonic: of or involving sound waves with a frequency above the upper limit of human hearing.
Def, Infrasonic: relating to or denoting sound waves with a frequency below the lower limit of human audibility
