Veteran SPL competitor Eric Alexander, who is a 14-time World Finalist in dB Drag and MECA competitions, amazed the MECA crowds during the 2007 World Finals during his record setting Drive-By bursts which measures an incredible 136.7dB SPL average for over 30 seconds. The certified SPL meter was placed just 6-feet away from the vehicle. This score is 3.5dB over the previous record! Not only did Eric do this feat once, but he did it again to honor the crowd with a second run measuring over 137dB Eric's windshield broke from all the SPL pressure.
