If you are among thousands of exhilarated football fans screaming and yelling in a stadium you better watch out for your hearing, or the consequences could be serious.
Noise levels in a football stadium can reach as high as 117 dB. At this level, just four minutes of exposure could cause permanent hearing loss.
Hearing loss typically happens gradually, and being at one game in a stadium is unlikely to result in permanent damage. You are more likely to experience temporary hearing loss, but this is an indication that some damage has occurred.
If you go frequently to watch live football without taking steps to protect your hearing, you may already have suffered permanent hearing loss.
The easiest way to provide significant hearing protection is to use earplugs while at the game. You can buy earplugs inexpensively at any drug store.
