Turn up the volume

The experience of watching sports isn't just about what we see...it's also about what we hear. Some sporting sounds are iconic and beloved, like the crack of the bat at a baseball game. But others are more maligned, like the grunting and shrieking noises certain tennis stars make every time they hit a shot. Retired player Monica Seles was once recorded at over 98 decibels, almost as loud as a pneumatic drill. Now women's tennis is trying to turn down the volume, announcing plans to crack down on excessive grunting and yelling before disgruntled fans put the sport on mute. Fortunately for those who like their sports loud, there's no such controversy with the aural experience at other athletic events, where more volume means more fun.
