Sound Unit Intro

After watching the sound unit intro video I learned that sound travels in waves. You can measure sound by frequency and amplitude. Frequency is how fast or slow and amplitude is how soft or loud. Another fact I learned from the video is that there are two forms of waves: indirect and direct and the types represented by those are diffusion, reflection and absorption.

Another video we watched was the Today Show video. This video talked about how hearing loss is being more impacted today then it has been in the past. This is due to the large amount of loud noise in todays society. It also talked about how you should get your hearing checked, because hearing is something you shouldn't miss out on in life; the hearing aids are more advanced then what they used to be. After watching the video I realized that my noise exposure hasn't been very good for my ears. I need to be more careful with my volume choice when listening to music and I also need to protect my ears when going to concerts, etc.
