The graph below shows data from a national survey on a wide range of health
characteristics. Hearing tests were conducted as part of the study. The data shown are
based on samples of Americans aged 12-19; 2,928 individuals in 1988-1994 and 1,771
individuals in 2005-2006. Over the same time period, use of MP3 players and other
personal listening devices increased. The Apple iPod was introduced in 2001, and 100
million of them had been sold by April 2007.
What can we conclude from the graph on hearing loss, considering that use of
personal listening devices also increased over the same time period?

Use of personal listening devices was associated in time
with increased adolescent hearing loss.
