Bagger Beatz is a sound competition format developed specifically for motorcycles. In a Bagger Beatz competition, contestants compete against one another to see who has the loudest sound system. Each contestant's score is comprised of two components... "Peak SPL" and "Broadband Peak Average". The Broadband Peak Average component is new and will ensure that the contestant's sound system is capable of playing music across the entire musical spectrum. The average of these two components represents the contestant's overall score. The contestant with the highest overall score wins.
Peak SPL (Sound Pressure Level) is used to determine how "loud" the stereo system can play.
Broadband Peak Average is used to ensure the system is capable of reproducing the entire musical spectrum. BPA is calculated from 30 individual peak-hold SPL measurements that are centered on 1/3 octave frequencies.
Competitors may use the program material of their choice while competing.
The program material being played may originate from any type of source unit that has been specifically designed to play music.
The program material is restricted to music only. Test tones, sweeps, pink noise, etc. are prohibited.
Adjustments to the sound system are permitted during the measurement as long as no other applicable rules are violated during the adjustment process.
The contestant's engine must be turned off during the measurement process.
All contestant's must demonstrate that their ride's engine will start at the conclusion of the measurement. If the contestant's engine will not start then the score will be changed to 0.
Contestants may be accompanied by one passenger if so desired.
