Why Does Sound Travel?
by Nicolas Brasch
Review by Danesha
Sounds are vibrations that travel through the air, or other medium, like water. Sound travels in waves and the volume of a sound depends on the size, height and frequency of the waves that are created. How do our ears hear sound? Our ears have three sections; outer, middle and inner. The outer collects sound waves which are channeled to the middle ear, which hits the eardrum, then they're converted into signals that are sent to the brain.
If you like to know how sounds works, or if you are interested in facts about sound, read Why Does Sound Travel?
Latricia:This is interesting because we just finish learning about this in class.I also just finish reading a book that tells me that our ears has three sections.Before reading your essay I thought our ear only had one section.That amazing about what I just found out.

ReplyDeleteThis does seem like a good book to read, especially for someone who wants to learn more about sound and how we hear things. Good job!
