After everyone has had an opportunity to qualify, the 8 loudest contestants in each class will be randomly paired against one another in the quarter-final elimination bracket. Each pairing of competitors will compete against one another in a head-to-head fashion. The winner will advance to the next round of eliminations and the loser will be eliminated from the contest. This form of competition will continue (semi-finals and finals) until there is a winner for each class.
Qualifying Scores - Term-LAB will display and use SPL values with 0.01 dB resolution.
Elimination Scores - Term-LAB will display SPL values with 0.1 dB resolution.
