Why Do You Need A Vocal Booth?
If you’re wondering what a vocal booth is, it’s a room or space that dampens, diffuses, and absorbs outside and background noise. It improves the quality of sound recording for listening enjoyment by reducing reverberation and other unwanted sounds. Lessening or removing outside and background noises makes vocals clearer and drier for recording and listening purposes. It’s usually a small room within a larger workspace or studio.
Vocal booths can be small one-person spaces or larger multi-person ones, it depends on what you require and your budget. You can also use similar strategies to improve sound quality in an existing room. There are many reasons you may want or need a vocal booth. Recording voice or vocals for music may jump to mind first but that’s only one way people use them.
A sound booth or room can be used as a communication room for work or school, or for practicing vocals or music. The decreased noise and distractions improve listening for learning and make verbal communication clearer for video participation in meetings, class discussions, and even family and friend chats. For those recording videos, pod-casts, school lessons, audiobooks, or thousands of other purposes, a vocal booth can be very helpful.
Vocal Booth Designs
A vocal booth is a designated room or space that surrounds and encloses the occupant or occupants. It reduces noise movement and reverberation into and within the space for clearer vocal and audio presentation and reception. A booth can be designed as a permanent room within a room, or as a portable enclosure that can be collapsed or dismantled to move or remove as needed.
A permanent vocal booth is constructed into an existing space using materials that dampen, absorb, and block noise transmission. They require knowledge of acoustical design and soundproofing materials to be effective. There are often separate layers to control sound movement so microphones don’t pick up unwanted vibration and soundwaves. Permanent acoustically treated sound rooms are more expensive to build but are well worth it if the budget permits.
Portable means it can be erected where and when needed, and dismantle and stored when not. They are comparatively inexpensive but often not as effective as a well-constructed permanent booth. Having said that, portable sound isolation structures are an excellent alternative to their permanent counterpart, and often easily made by DIYers. Whether made of portable acoustic panels, egg-carton foam housing for a mic, or other materials, they can be moved to capture sound from different directions.
How to Build Soundproof Recording Booth From Scratch
When listening to a song or presentation, the vocals are the most important part. Music and other noises shouldn’t overwhelm the singer or speaker’s voice. So, keeping the voice front and center makes for better recording and thus listening. Whether you’re an amateur or professional vocalist, blog or social media presenter, audio-video clip uploader, or just prefer quality audio, a DIY sound booth may be the ticket.
Building a soundproof recording booth is much like building a room within a room. However, it should be noted that the booth isn’t really soundproof. The concept is to break the soundwave transmission link between the outside and the inside, also known as decoupling, and to control reverberation and bounce generated within the booth. A small space makes for less reverb but can produce hollow audio, not a dry, crisp, ready for radio sound. If you’re considering building a permanent booth, here are some suggestions:
Step 1. Location
Choose a location where there is little traffic or noise. The best location is a corner where two concrete walls meet, such as a basement. It should be away from the furnace, plumbing pipes, HVAC ducts, and the laundry too. Most sound booths are small, varying from 12sqft (3’x4’) to 24sqft (4’x6’); large enough for one or two people and some musical instruments if required.
Step 2. Design
To minimize sound transfer, you’ll want to decouple the sound booth from the rest of the room. That means walls, ceiling, and floor, hence, a room within a room. Traditional building practices don’t decouple walls, so consider building separated walls. Metal transfers less noise than wood and is lighter, so metal studs are a good choice.
Stone wool acoustic insulation in wall cavities adds mass and absorbs sound waves, as does a layer of mass-loaded vinyl (MLV). Doubling the drywall thickness and using acoustic adhesive to secure the second layer will help further decouple the walls too. Seal and insulate outlet and receptacle openings so air, and thus sound, can’t leak in.
To separate the floor, use rubber-backed floating floor tiles or neoprene matting, they’re easier and less expensive than building a separate floor. Use the inner portion of the double wall to carry the ceiling and further isolate the booth from outside noise, also double the gypsum layer on the ceiling.
Step 3. Other Considerations
The small space can warm up quickly, so use LED lighting, it produces good light but less heat. To dissipate heat and improve ventilation, an intake vent should be built in down low and the outlet up high. Off-set the intake and outlet as they go through the double wall using flexible insulated duct tubing. Using a 3-speed fan to push air in will also help force it out, keep the heat down, and improve the oxygen supply.
The door should be solid and swing-out, not into the booth. It’s much easier to get in and out if the door swing doesn’t take up half the floor space. If windows are needed to view the musicians or producer, orient them so that’s where they look. Another design consideration is electrical; plan out the location of receptacles and audio hook-ups before building. An off-set path for wires and feeds helps reduce noise transfer through the double walls too.
Step 4. Wall Treatment
The decoupled booth controls noise coming into the booth but not so much the noise produced inside. If the sound seems boxy, use a sound meter to check frequency ranges. Consider adding acoustic panels to the walls, corners, ceiling, and even the door. The panels absorb low mid-range frequencies and trap bass resonance to improve the sound. Once the booth is set up, you can produce radio quality vocals whenever you need them.
27 Creative DIY Soundproof Recording Studio Booth Projects
Whether building a permanent or portable soundproof booth, the design, location, materials, and purpose are unique to you, as is the budget. The outlay cost is often determined by expected or hoped-for return, which again, is often individual. If only required for a brief period of time, then a permanent booth may not be ideal.
You may want to start with a portable and work up to a built-in booth or consider adding acoustic panels and treatment to an existing room to improve its sound quality. To help you out, here are 27 projects or suggestions to improve sound control.
Permanent Vocal Booth
A permanent DIY soundproof booth will improve sound quality, and need not break the budget. Check out these design summaries and links.
1. How I Built Sound Booth
Stuck in an apartment? Here’s a permanent booth built using modular design construction which allows it to be dismantled and moved, or stored. Approximately 6’ wide, 8’ long, and 7’ tall, the walls, ceiling, and floor are framed using 2×3 lumber with fiberglass insulation filling the stud cores. The insulated floor framing is sandwiched between OSB.
The walls and ceiling have drywall on the outside and OSB on the inside, which is then covered with a layer of soundboard and drywall using glue to help decouple the layers. Foam acoustic panels cover the walls, door, and ceiling, and carpet on the floor help to further deaden noise. A sound test is also included plus a link to plans and documentation.
2. DIY Soundproof Booth
This clip shows the construction of a 7’ long, 4’ wide, and 7’ high booth built in an upper floor bedroom. The 2×4 floor frame rests on interlocking neoprene foam mats and is insulated with rock wool batts and covered with OSB. 1×4 pine is used to frame the walls and ceiling. 1/4” plywood covered with carpet faces the exterior of the wall and ceiling panels.
Wall and ceiling cores are filled with rock wool and covered with 1/4″ ply, which is then covered with acoustic foam. A matching hinged insulated panel with a built-in window forms the door and is also covered with sound-deadening foam. The floor is covered with carpet tiles for more sound treatment.
3. Vocal Sound Booth Whisper Room Build
This is the first part of a video series that includes building instructions and materials for a modular constructed 47”x47”x80” vocal booth, plus links to materials and equipment. The floor is constructed of 2×4 framing covered with MDF, and the walls and ceiling with 1×3 lumber sheathed with 1/4″ plywood.
Wall frames wrap 2” ridged pink foam sheeting which fills the frame – there are no studs, making for a very lightweight composite panel. All Styrofoam surfaces are coated with contact cement and then covered with 1/4″ plywood. Interior wall and ceiling surfaces are also covered with acoustic foam. Electrical and ventilation are also included in this design.
