## 02 – Application Definition
**H2:** What Is Recording Booth Acoustic Glass?
A Recording Booth is a small, fully sealed acoustic enclosure built for one purpose: **capture clean audio without outside noise, and keep the performance inside from bleeding out.** Whether it is a vocal booth, a voice-over booth, a podcast studio, or a telemedicine / court-reporting recording room, the requirement is fundamentally stricter than an office pod. Speech must be isolated across the **full vocal range (125 Hz – 8 kHz)**, not just the 500–4000 Hz speech band — which means the glazing must control both low-frequency rumble and high-frequency sibilance.
Recording Booth Acoustic Glass refers to the engineered, typically **composite laminated-insulated** glass panels and viewing windows that deliver this elevated isolation while remaining safety-rated, optically clear, and integrable with the booth's sealed framework. Unlike a standard office pod — where STC 40–45 is acceptable — a recording booth commonly targets **STC 47–55 glass**, because the microphone hears what the human ear forgives.
## 03 – Acoustic & Design Requirements
**H2:** Why Recording Booths Demand the Highest Glass Performance
| Requirement | Why It Matters in Recording Booths |
|-------------|-----------------------------------|
| **Full-band isolation (125 Hz – 8 kHz)** | Vocal booth must kill HVAC rumble, traffic, and room reflections — not just office chatter |
| **Low-frequency control** | Asymmetric pane thickness + mass law defeats the coincidence dip at bass frequencies |
| **Zero flanking** | Window frame, perimeter seal, and cable passthrough are the #1 leak paths |
| **Viewing window** | Engineers need visual contact with the performer — large window, zero acoustic penalty |
| **Interior acoustic treatment compatibility** | Glass must sit flush with foam/bass-trap treatment, no recesses to trap reflections |
| **Safety + durability** | Tempered-laminated, post-breakage retention, suitable for repeated hardware mounting |
| **Compact footprint** | Booths are small (~1.5–2.5 m²); thick glass must still fit the wall cavity |
> **Key insight:** In a recording booth, the **viewing window is the weak point** — it is the one hard, reflective, potentially thin surface in an otherwise fully treated room. Getting the window build right is 50 % of the acoustic battle. This is where our composite glass wins.

**Viewing Window Design Principle:**
- **Angled / splayed glass** (5–10°) to break standing waves and avoid flutter echo between booth walls
- **Flush-mount** with interior acoustic treatment — no reveals or recesses
- **Double-sealed perimeter** — structural silicone + EPDM compression gasket
- **Asymmetric panes** — different thicknesses on each side shift the coincidence frequency below/above the vocal range
## 06 – Acoustic Performance & Testing
**H2:** Acoustic Performance
- **Glass-only STC:** 47–55 (by configuration)
- **Rw (EN ISO 717-1):** up to 53 dB
- **Frequency range:** Engineered for **125 Hz – 8 kHz** (full vocal / instrumental range), not just 500–4000 Hz
- **Coincidence control:** Asymmetric lite thicknesses (6/10 or 8/12) push the coincidence dip away from the vocal band
- **Damping layer:** Acoustic PVB/SGP adds viscoelastic damping, critical for mid-high frequency absorption
- **Mass law:** Total glass mass ~30–50 kg/m² — heavy is quiet
- **Test standards:** ASTM E90 / E413, EN ISO 10140 (glass transmission loss); ISO 23351-1 (complete booth speech/audio level reduction)
- **Complete-system reference:** Glass solutions engineered for recording booths are evaluated under **ISO 23351-1** — accurately stated as a *booth system* standard, **not** a "glass certificate"
> **Performance promise:** We do not sell "probably quiet enough." We model the full build-up against your target curve and supply the calculation note with every quotation.

## 12 – FAQ
**H2:** Frequently Asked Questions
1. **What STC should a recording booth window have?**
For a vocal/podcast booth, target **STC 47–52** glass; professional broadcast/ADR reaches **STC 52–55** with composite or triple-glazed builds.
2. **Is laminated glass alone enough?**
8+1.52PVB+8 (STC ~43–45) is entry-level. For true studio isolation, pair laminated + IGU (composite) to engage both damping and mass-air-mass principles.
3. **Why asymmetric panes?**
Different thicknesses (e.g., 6 mm + 10 mm) shift the coincidence frequency away from the vocal range, preventing a sudden mid-band transmission spike.
4. **Can the window be flush with acoustic foam?**
Yes — we design flush-mount framing so the glass face aligns with your interior treatment, avoiding reflective reveals.
5. **Do you offer angled/splayed windows?**
Yes — a 5–10° splay breaks standing waves and flutter echo between parallel booth surfaces.
6. **Can you machine holes for XLR / cable passthrough?**
Yes — CNC cable/vent labyrinth cut-outs with removable acoustic plugs, ±0.5 mm to your DXF.
7. **Can the window be Low-Iron and anti-reflective?**
Yes — Low-Iron + optional AR coating reaches ~91% VLT with near-zero glare, ideal for on-camera studio use.
8. **Can glass-only STC be guaranteed for the whole booth?**
No — only glass STC is certifiable per ASTM E90. Complete-booth performance (ISO 23351) depends on your full assembly; we provide the calculation note and support.
9. **What is the typical window size?**
600×900 mm to 1200×1500 mm is standard for recording booths; custom sizes available up to jumbo.
10. **Lead time and packaging?**
Samples 10–14 days; bulk 25–35 days FOB. Windows crated with EVA edge guards, vertical dividers, and clearly labeled assembly drawings.
