This project explores how age influences the ability to hear high-frequency sounds like the mosquito ring tone. The study involves testing different age groups with frequencies ranging from 30 Hz to 3 KHz and decibel levels from 0db to -33db. The age groups tested include 11-13, 14-15, 20-25, 30-40, and 40-50. By using headphones, participants undergo tests to determine their hearing thresholds for specific frequencies.

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.
Materials • 1 pair of headphones
Procedures • The person that I am testing wears
