Acoustic Specs: Choosing a Soundproof Booth for Schools
Why acoustics and a soundproof booth matter in schools
Good acoustics are essential for learning. Excessive noise and poor speech intelligibility reduce concentration, increase teacher strain, and impair reading and language acquisition — especially for younger children and students with hearing or attention needs. A well-specified soundproof booth can provide a controlled space for one-on-one interventions, testing, remote lessons, speech therapy, or quiet study. When schools evaluate a soundproof booth, they should start with measurable acoustic specs rather than marketing terms.
Key acoustic metrics every school administrator should understand
Choosing the right booth requires familiarity with a few core acoustic metrics. These numbers explain how much sound is blocked, absorbed, or reflected, and they inform whether a booth will meet pedagogical needs.
- STC (Sound Transmission Class): Measures how well an assembly (wall, door, or booth shell) reduces airborne sound between adjacent spaces. Higher STC means better isolation. For speech privacy in sensitive contexts you typically want STC 45+, but for many school uses STC 30–40 is often acceptable.
- dB reduction (in-situ reduction): Practical measure of how many decibels of existing ambient noise are reduced inside the booth. This is often expressed as 30 dB noise reduction, meaning the inside level is 30 dB lower than outside under specific conditions.
- NRC (Noise Reduction Coefficient): Indicates how much sound a material absorbs (scale 0–1). Higher NRC reduces reverberation inside the booth, improving clarity.
- RT60 (Reverberation Time): Time it takes for sound to decay 60 dB in a space. Shorter RT60 supports speech clarity in small booths (target typically 0.3–0.6 s for small study spaces).
- Speech Transmission Index (STI): Objective metric of speech intelligibility; used in designs requiring high comprehension (speech therapy, assessment).
Recommended acoustic targets for school booths and rooms
While requirements vary by country and building code, the following are practical targets schools can use when evaluating booths or pods:
| Metric | Practical target for school booth | Why it matters |
|---|---|---|
| STC | 35–45+ | Provides good isolation from classroom noise; 45+ recommended where confidentiality or testing occurs |
| dB reduction (outside→inside) | 20–30 dB typical; 30+ dB preferred for quiet testing | Directly reduces intrusive ambient noise |
| NRC | 0.6–0.9 (interior surfaces) | Controls internal reverberation; improves clarity |
| RT60 | 0.3–0.6 s (for small booths) | Lower RT60 improves speech intelligibility |
These values are guidelines. Specific needs depend on the intended use (assessment, therapy, quiet study, teacher prep) and the building's ambient noise levels.
How to interpret manufacturer claims: STC vs dB reduction
Manufacturers often advertise a single number such as 30 dB noise reduction or an STC rating. It's important to know the difference:
- STC is measured under lab conditions for partitions; it does not automatically equal dB reduction in a particular building installation.
- 30 dB noise reduction may be measured in typical conditions but check test method and frequency weighting (A-weighted dB(A) is common).
- Ask suppliers for measured insertion loss data, testing reports, or on-site measurements in a similar environment.
Example calculation: What dB reduction do you need?
Simple rule: decide your target internal noise level and subtract it from the ambient noise level. Example:
- Ambient classroom noise: 60 dBA (typical busy classroom hallway)
- Desired inside level for focused testing: 35 dBA
- Required reduction: 60 - 35 = 25 dB
This means a booth with a realistic 25–30 dB reduction will meet the need. If you have higher ambient noise, you need better isolation.
Design and operational factors beyond acoustic numbers
Acoustic specs are necessary but not sufficient. Consider these practical factors before procurement:
- Ventilation and fresh air: A booth must provide adequate ventilation and thermal comfort without compromising noise isolation. Mechanical ventilation with low-noise fans and ducting or an integrated fresh air system is essential.
- Fire and building codes: Ensure the booth meets local fire egress, electrical, and access regulations. Many schools require certified fire-resistant materials and approved installations.
- Accessibility: ADA or local accessibility standards may require certain door widths and thresholds for wheelchair access.
- Power and connectivity: Provide integrated power, data, and charging points for teaching devices and monitoring equipment.
- Durability and maintenance: Choose materials that resist scuffs, are easy to clean, and have replaceable acoustic panels.
- Flexibility and mobility: Some schools prefer modular or movable pods for multi-use spaces; others need fixed installations.
Comparing booth types: modular pods vs. built-in rooms
Deciding between a modular soundproof booth (freestanding pod) and a built-in room involves trade-offs.
| Option | Pros | Cons |
|---|---|---|
| Modular pods (freestanding) | Quick install, relocatable, lower construction disruption | May have lower STC than a fully built room; floor and wall flanking can limit isolation |
| Built-in rooms | Potentially higher acoustic performance, full integration with building systems | Higher cost, longer construction time, less flexible |

Procurement checklist: what to ask suppliers
When evaluating booths, request the following from each supplier:
- Independent acoustic test reports (STC, insertion loss, and NRC values)
- On-site sample measurements or references at similar ambient noise levels
- Details on ventilation rates, sound level of fans (dBA), and filter specs
- Fire rating certificates and compliance with local building codes
- Accessibility options and internal dimensions for intended users
- Lead time, delivery, installation scope, and warranty terms
- Cost breakdown (unit price, installation, optional electrical/networking, maintenance)
Maintenance and long-term considerations
Plan for periodic checks of seals, door alignment, fan performance, and acoustic panels. Replace filters as recommended by the manufacturer. Keep a log of any repairs to ensure the booth continues to meet acoustic and safety specifications over time.
Quick decision guide: matching a booth to common school needs
- Speech therapy / confidential testing: Target STC 45+ or equivalent 30+ dB real-world reduction. Require verified measurements and quiet ventilation.
- One-on-one tutoring / remote conferencing: 25–30 dB reduction is often sufficient; comfortable seating, lighting, and good ventilation are priorities.
- Quiet study or library pods: NRC for interior surfaces and low RT60 for clarity; STC 30–40 acceptable.
Cost vs performance: what to expect
Higher acoustic performance usually costs more. A quality modular soundproof booth with verified 25–35 dB reduction and integrated ventilation is a mid-range option. For the highest confidentiality or clinical testing needs, consider investing in purpose-built rooms or High Quality pods with higher STC. Evaluate total cost of ownership including installation, maintenance, and lifespan.
