A fully soundproofed private rehearsal studio located in San Diego's North Park community. Though it looks plain, a full range of insulation, decoupling, and sealing techniques were to insure that little, if any, sound will be heard outside while the band is playing. The magic is in the walls themselves and should not be confused with acoustic treatments (e.g. foam panels and similar), which change how sounds behaves inside the room but does little to prevent it from leaving or coming in.
