[QUOTE="ThxOne, post: 8720653, member: 675210"] From the IASCA Revised SQ rules: "Sound judging for Tonal Accuracy, Sound Stage and Imaging will be performed at a system volume level between 80 and 90 dB. If the noise floor at an event is too high to properly Judge at 90 dB, the volume level will be adjusted up in 5dB increments to compensate. The volume level for judging will be set by the Judge using a portable SPL meter and the Pink Noise track from the CD, establishing a consistent volume level of evaluation for each vehicle at an event. Judges will record the decibel level used on each score sheet. All vehicles in a class will be evaluated at the same level." The audio engineer in NY also told me they listen and mix @ between 80db and 90db. A pattern emerges. I am getting excited!!! [/QUOTE]
