It's pretty simple:
- the more power the machine draws for hashing the more heat it generates
- the more heat you need to blow out the faster and larger the fans and thus the bigger the noise
- sound insulation in a box works but you don't solve the heating issue so you need soundproof ducts and you need more fans for the airflow and that air to be blown somewhere where the noise will also be unleashed.

this is perfectly true, reducing one problem causes another to increase.
I think that the maximum that can be done is to direct the noise to the other side with sound absorbers, where it is less disturbing (to the neighbour I guess)
audio technology has some possible solutions, for example
