Another solution is: money. Most of the companies which make treatments offer paid consulting services. So if you don't have the time and patience to do it on your own, you can throw cash at it.
If that's not an option, you can usually get a little free advice them them anyway when you are about to purchase some product.
I like to do things on my own; this helps my desire to understand how things work. A good introduction to the science of acoustics is the book Master Handbook of Acoustics by F. Alton Everest.
