Research has shown that early onset of hearing loss can be attune to prolonged, intense exposure to music at impacting decibels from headphones and rock concerts. In order to test this relationship, researchers enrolled a group of 25-35 year olds and followed them for 15 years, asking participants to document their music listening habits in a journal that would be regularly checked by the research professionals. The journals would be interpreted and an overall average exposure level over a specified period of time would be quantified into four quartiles based on decibel strength of the music experience the participant endured. Signs or symptoms of early hearing loss would be dichotomized into either expressing a decreased hearing capability or not based on an examination at the end of the study. The following partially filled table represents the results of the study.

  Hearing loss No Hearing loss Total
decibel strength [0-60] -non expose 29 85 114
decibel strength [61-100] -2nd lowest 41 91 132
decibel strength {101-125] -3 rd lowest 63 186-63=123 186
