Taylee - ch18 DYV

 Summary: We learned earlier that our ears our designed in a way that protect themselves from our voice. So in this chapter that discusses hearing, we need to remember that our perception of our self is distorted. Just like the anatomy of making sound, the anatomy of the ear is amazing when you compare its size to what it accomplishes. Also just like our vocal folds, the nerves and muscles of the ear are extremely sensitive, and once hearing is lost, it cannot be regained. Our ears are most sensitive to sounds in the frequency range between 700 and7000 Hz. Another thing to consider is that it takes more energy to produce an audible low note than an audible high note. This is due to the high frequency levels of higher pitches. Take care to not overwork the muscles of the ear. They are like all muscles and need rest.

Key Terms: Threshold of pain.

Key Concepts: A decrease in hearing ability can never be restored. You don't hear yourself as others hear you.

Making Connections: I guess it's pretty obvious, but I never thought of ears as being able to get tired! I don't get a scratchy sensation in my ears like I do when my voice is tired, or a soreness like I get in my legs after running, so I didn't always recognize when my ears needed rest. Since they don't have as obvious warning signals as other muscles, I need to figure out what my ear's warning signal is. I've decided that I get mentally tired when my ears are done. I feel a lot of anxiety and so I naturally seek out a quite relaxed environment to ease my mind. Hopefully I can better develop my awareness so that I can make better decisions concerning my hearing.
