  1. How your age affects your Hearing

  2. Background I picked this project because I was interested in the mosquito ring tone. The mosquito ring tone is a cell phone ring tone that emits a high frequency tone that is inaudible to adults. It is generally used in school so that teachers cannot hear a students cell phone ringing. I was interested because some people could hear it and some couldn’t. I wanted to know at what age can you hear certain frequencies. I tested different age groups and different frequency's. I will test a range of frequencies between 30 Hz to 3 KHz and a decibel range of 0db to -33db. I am testing The age groups of 11-13, 14-15, 20-25, 30-40, and 40-50.
