Unfortunately, all walls are somewhat flexible. Any motion caused by sound striking one side of the wall will result in sound radiated by the other side, an effect called coupling. If the sound hits a resonant frequency, the wall will boom like a drum. Most isolation techniques are really ways to reduce coupling and prevent resonances.
Put one of these on each vent connected to the studio ducts, even those in other rooms. If this isn't enough, you can add a second unit in front of the first.

A mathematical procedure is developed for calculating the parameters of a singlelayer perforated-plate acoustic liner in order to achieve a specified acoustic resistance and reactance for single-frequency excitation. The method includes the standard impedance terms, due to viscosity, radiation, and backing effects, and also the terms due to high sound amplitude and steady tangential airflow. Emphasis in the analysis is on these latter non-linear effects. Specification of acoustic resistance and reactance (at one frequency and set of environmental conditions) means that two quantities are used to determine the four liner parameters: fractional open area of plate (porosity of plate), thickness of plate, diameter of hole perforations, and depth of backing cells.

External windows are a real problem, since a single layer of ordinary glass is only slightly better sound insulation than nothing at all. Storm windows are a big help, especially if you fill the space between panes with fiberglas. (You don't really need to see outside, do you?) Thermal glass is actually worse than a single pane window because the narrow air space tends to resonate.

You can easily hear this by putting your ear close to a wall: the quality of sound will change because the reflections off the wall interfere with the direct sound. The effect is at its worst when the distance the reflected sound travels is only slightly longer than the direct distance.
