We're planning on building a house with a basement, to include a music room. I can’t "build a studio" as such, just hope to optimize construction for better isolation than what a basement would normally have. I won't be building a room within a room or anything that involved. I plan to present the builder with options for them to assess for cost and practicality. The diagram on p. 63 of Rod’s book is helpful, and using RC-1 seems the best option if affordable. These are probably newbie questions, but this subject seems overwhelming at times, when we’re already challenged just building a house. Exterior walls of studio room: do I want insulation or air between drywall and exterior wall? Insulation seems logical, but I’ve read about the value of air. Interior walls: If we can only afford single walls, would using RC-1 on one or both sides still be an improvement? And fill this with insulation? Does anyone know of a resource discussing insulation and different materials for sound absorption (as opposed to treatment)? Like Owens Corning 703, 705, Roxul, Audimute’s sound absorption sheets (Cubase), etc? Products like QuietRock or Sheetbok seem way out of my budget. Thanks for any illumination.
