Best practices for soundproofing your Music Studio rooms
Soundproofing refers to the noise transfer from one room to another. To control the amount of sound transfer between rooms within your Music Studio and between your Music Studio and adjoining spaces in your building it is best to think about the following:
Use dense and air-tight materials.
Walls are the most soundproof part of the studio.
Alternatively, problem areas are:
Pipe or cable pass-through
Anywhere the wall is penetrated
Shared HVAC ductwork that interconnect rooms
Walls that do not extend to the structure above (floor, ceiling or roof)
There are two common methods for creating an effective soundproof environment:
#1 – Purchase a prefabricated vocal booths
We recommend installing a prefabricated vocal booth (such as www.whisperroom.com) in your recording studio.
Prefabricated vocal booths are a great solution for achieving a high degree of soundproofing and room acoustics.
They can be purchased in a variety of sizes and configurations depending on your needs.
#2 – Construct walls, ceilings doors and windows with the follow specifications in mind
Interior and exterior walls and ceilings. A best practice is to use dense and airtight materials.
We recommend extending a solid wall to the ceiling or roof above. If this is not possible, a “solid cap construction” ceiling (2 layers of wallboard) is recommended.
Drop ceilings are not recommended for Music Studio facilities.
Cinder blocks, poured concrete, or brick construction are ideal wall materials.
For new walls, we recommend a single stud wall with 2 layers of wallboard on each side of the studs:
Homosote sound board (inside layer)
5/8” gypsum board on the outside faces of the studs
Rockwool batt insulation in the stud cavity
Solid walls (no windows or doors) provide the highest level of soundproofing. Tips for optimizing areas that provide lower levels of soundproofing:
Windows – Ideally use double-glazed with thick lites (i.e. 3/8” to 1/2”) and a 2 to 4-inch air space in-between. One of the lites should be laminated, which provides sound reduction properties.
Doors – Use solid-core acoustical doors with non-adjustable neoprene gaskets (at the head and jambs), as well as an automatic drop seal at the threshold to provide the best sound isolation.
Pipes or cable pass-throughs – Avoid using these when possible. Tightly seal anywhere the wall is penetrated.
If possible, use Packaged Terminal Air Conditioner & Heat Pump units (PTAC).
Forced hot air HVAC systems are not recommended in the recording studio rooms. If the existing facility uses forced hot air, you may need to contact a professional to help design a system that provides very low background noise conditions.
Avoid shared HVAC ductwork that interconnects between Music Studio rooms (especially recording studio rooms). Sound will travel through the ductwork transferring a significant amount of noise between rooms.
Audio Wiring and Connections – Audio equipment uses specialized cable connections and wiring. It is best to contract with an audio specialist to help determine the needs of your Music Studio. You may consider a cable pass-through like a “Wiremold 4000 large raceway cable channel.” This allows for a custom and organized way for interconnectivity between various rooms in a recording studio facility, but minimizes the sound that passes from one room to another.
