(NEW YORK) -- A new study suggests that exposure to MP3 players may cause hearing loss, according to HealthDay.
Researchers looked at thousands of New York City residents and estimated how much noise the residents were experiencing throughout their day. The findings, which were published in the journal Environmental Science & Technology, found that people damaged their hearing by listening to MP3 players, commuting on public transportation, and going to loud concerts.
One thing researchers are worried about is that MP3 players can run for days, while their precedents were battery operated.
The stydy did not directly measure exactly what New York commuters were listening to.
