Psychlone is an auto sound competition format designed to capture the original excitement of a great sounding aftermarket car stereo installation. This format is also designed to cater to the vast majority of auto sound enthusiasts who design and build their systems to sound great at moderate to high listening levels. Each contestant's sound system is scored based on how loud it will play (SPL), the frequency response of the system (RTA), and Installation Quality. These elements form the basis for a Psychlone event.
Sound Pressure Level (SPL) is used to determine how "loud" the stereo system can play.
Real Time Analysis (RTA) is used to determine the frequency response of the system.
Installation Quality is used to determine if the fundamental elements of good aftermarket installation are followed.
Competitors must use a music track from the dB Jams Volume 22 competition CD (or a digital copy of the CD) for the SPL portion of the competition.
If an event takes place prior to the release of the official CD, then the previous year's CD may be used in the interim.
Adjustments to the sound system may be made while the vehicle is being metered for the SPL portion of the competition provided no other applicable rules are violated.
Adjustments to the sound system are prohibited while the vehicle is being metered for the RTA portion of the competition.
The contestant's vehicle may be running while in the judging lanes as long as the following conditions apply:
Operation of the vehicle or sound system must not endanger the judge, competitor, spectators, or any real or personal property on the premises.
The vehicle's parking brake must be set.
The wheels must be chocked.
The hood must be closed.
The maximum engine idle speed must not exceed 2000 RPM.
A remote "engine kill switch" must be easily accessible from outside of the vehicle for those competitors that are bolting (clamping, strapping, etc.) the doors of the vehicle closed while in the judging lanes.
It is the competitor's responsibility to comply with the conditions listed above. Competitors found to be in violation of one or more of these conditions may be eliminated from the competition.
Competitors may choose to remain either inside or outside of the vehicle during competition provided no other applicable rules are violated.
Contestants who elect to remain inside of the vehicle during metering must meet the following requirements:
Only the contestant is allowed to be inside the vehicle. Passengers are prohibited.
The contestant must sit in the driver's seat.
SPL Measurement - The contestant must wear adequate hearing protection at all times. Removal of the hearing protection while inside of the vehicle will result in a zero score.
The contestant must sign a dBDRA entry form that includes a waiver stating that the contestant understands that "exposure to high sound pressure levels may result in temporary or permanent hearing loss".
It is the contestant's responsibility to take adequate safety precautions when operating the sound system at high sound pressure levels.
The driver's door must remain in the fully open and latched position during the SPL measurement portion of the competition. (The remaining doors, windows, or other openings in the vehicle can be open or closed at the competitor's discretion provided no other applicable rules are violated.)
Local laws, ordinances, show policies, or safety issues may prohibit excessive noise. If this is the case, then all doors, windows, and other openings to the vehicle must remain closed when competing.
All auto sound equipment must be permanently installed within the vehicle and shall not interfere with the normal use of the passenger compartment. (The area in front of the B-pillars.)
