How loud would a footballer need to shout to defend a shot?

Rikesh Kunverji


During the 2-0 victory over rivals Tottenham Hotspur, Arsenal's Benjamin White was spotted shouting at an attacking player as a means of last-ditch defending. This paper assumes that shouting was an effective means of defending, and calculates an estimate of how loud the shout would need to be to force the ball to roll quicker, causing the shot to go askew. White would have had to shouted at an unphysical value 157.8dB, comparable to the sound of a military jet taking off, in order to defend using his vocal cords.
