WashSingh, we don't publish generic dB measurements on the equipment because it can vary significantly by site. Differences in bay height/width, wall coverings,
doors and even outside landscaping can significantly alter acoustics at a specific location. Different styles of dryers (on-board, 3 fan, 4 fan w/follower, etc.) will also all be different. Because of these, I agree with CarWashIreland that it's often better if you took readings with the
apps available to take readings that will work for you.
I do have a couple of generic versions that I can send if you would like to send me your email address, but don't know how well they would match to what you have.
