The Science of Acoustic Glazing: Coincidence Dip Elimination
Standard monolithic glass suffers from a severe acoustic weakness known as the "coincidence dip" — a specific frequency band (typically between 1,000 Hz and 3,000 Hz, where human hearing is most sensitive) where the bending wave velocity of the glass matches the sound wave velocity in air. At this frequency, ordinary glass allows sound energy to pass through almost unimpeded.
Super Safety Solution manufactures Acoustic Laminated Glass using specialized Acoustic PVB (Tri-Layer Sound Interlayer) composed of a viscoelastic acoustic core layer sandwiched between two structural PVB films. This elastomeric core dampens vibrational energy, breaks shear waves, and completely flattens the coincidence dip, creating calm, quiet interior spaces even adjacent to busy Indian highways and airport corridors.
Acoustic Glass Specification & STC Rating Matrix
| Configuration | Nominal Thickness | STC / Rw Rating | Noise Reduction Performance | Primary Deployment |
|---|---|---|---|---|
| 4mm + 0.76mm Acoustic PVB + 4mm | 8.76 mm | 36 dB | Blocks conversation, mild street traffic | Residential bedrooms, private study rooms |
| 5mm + 0.76mm Acoustic PVB + 5mm | 10.76 mm | 38 dB | Dampens heavy commercial avenue noise | Corporate conference rooms, hotel guestrooms |
| 6mm + 1.52mm Acoustic PVB + 6mm | 13.52 mm | 40 dB | Significant reduction of diesel bus/truck rumble | Hospital patient wards, highway-facing facades |
| 8mm + 1.52mm Acoustic PVB + 8mm | 17.52 mm | 42 dB | Exceptional low-frequency attenuation | Airport perimeter hotels, recording studios |
| 6mm Acoustic Lam + 16mm Argon + 6mm Low-E (DGU) | 28 mm+ | 46–49 dB | Maximum acoustic isolation + thermal U-value | Grade-A IT towers, LEED-certified skyscrapers |
Dual Benefit: Sound Control Combined with Life Safety
Unlike acoustic foam or acoustic plasterboard, acoustic laminated glass provides panoramic natural light and architectural beauty alongside heavy structural security:
Fall Prevention & Safety
Complies with IS 2553 Class A safety glazing. If accidentally broken, the glass adheres permanently to the interlayer with zero fallout hazard.
99% UV Filtration
The acoustic PVB matrix blocks 99.5% of harmful UV rays, protecting luxury hotel furnishings, executive carpets, and timber floors from fading.
Forced Entry Deterrence
Resists crowbar attacks, bricks, and blunt intrusion attempts far longer than standard toughened glass, delaying unauthorized entry.
