CSEF · 2002 Mammalian Biology

Megan E. Hamilton · La Reina High School, Thousand Oaks

Overview

Objectives/Goals The objective was to determine whether or not teenagers experience a temporary hearing loss after being exposed to loud music. Methods/Materials I picked a song and tested it for its decibel level using a sound meter. Then, prior to listening to the music, I tested the subjects' hearing using tuning forks of 256Hz, 512Hz and 1024Hz. After the subjects listened to the music, I tested their hearing again with the same tuning forks. The independent variable was the 20 subjects and their ages; the dependent variable was the reaction to the tuning forks after listening to the music. Results After listening to the music, 60% of the subjects tested were unable to hear the tuning fork with the highest frequency (1024Hz). The remaining 40% of the tested subjects were able to hear all of the tuning fork sounds after listening to the music. Conclusions/Discussion Loud music can cause a temporary hearing loss in many teenagers.

Summary statement

I tested the hearing of teenagers after listening to loud music and found that many suffered a temporary hearing loss.
