The WTA has begun testing noise levels at tournaments in order to find a proper way to curb grunting. USA Today reports that the WTA began testing in the spring.

“There is more data to be done, there’s more assessment to be done on the different audible levels,” WTA chief executive Stacey Allaster said. “There are a variety of different environments that you need to assess the audible levels—indoor buildings, outdoor buildings, small venues, different surfaces, etc…we are committed to the strategy to drive excessive grunting out of the game, and we believe it’s through the next generation.”
