Accoustic tuning is something beyond the realms of most people and even most performance workshops.
You would need to spend a lot of time and money to tune an intake system properly and if you change anything afterwards you will change the accoustics again.
Personally I wouldn't even consider trying to accoustically tune anything that is before the throttle body... your time and money would be better spent testing flow on a flowbench as far as I'm concerned.
Even the guys in the article appear to have made a roughly calculated guess at the tuned length of the intake and then cut the pipe say 1cm at a time until they found peak power on a dyno.
