# What Is the Best Soundproofing Material? A Professional Guide
Choosing the best soundproofing material depends on factors like density, Sound Transmission Class (STC) rating, and application. Below, we break down top-performing materials with industry-backed insights.
Key Factors in Soundproofing Material Selection
- Mass & Density – Heavier materials block sound better (e.g., mass-loaded vinyl).
- STC Rating – Measures airborne noise reduction (higher = better).
- NRC Rating – Rates sound absorption (ideal for echo control).
- Flexibility & Thickness – Critical for walls, floors, and ceilings.
Top Soundproofing Materials Compared
1. Mass-Loaded Vinyl (MLV)
- STC Rating: 25-30 (per layer)
- Best For: Walls, floors, ceilings
- Pros: Flexible, high density, easy to install
- Cons: Expensive, requires sealing for full effectiveness
2. Mineral Wool (Rockwool)
- STC Rating: 45-50 (in wall assemblies)
- Best For: Cavity insulation, studios
- Pros: Fire-resistant, excellent absorption
- Cons: Can be bulky, requires framing
3. Acoustic Foam Panels
- NRC Rating: 0.7-1.0
- Best For: Echo reduction, recording studios
- Pros: Lightweight, affordable
- Cons: Poor for blocking low-frequency noise
4. Green Glue Compound
- STC Improvement: +5 to +15 (when used between drywall layers)
- Best For: Retrofit projects
- Pros: Dampens vibration, easy application
- Cons: Requires precise installation
5. Fiberglass Insulation
- STC Rating: 39-42 (in walls)
- Best For: Residential/commercial walls
- Pros: Cost-effective, thermal benefits
- Cons: Less effective alone, needs additional barriers
Industry Standards & Testing
- ASTM E90 & E413 – Standard tests for STC ratings.
- ISO 10140 – International sound insulation testing.
Final Recommendations
- For walls/floors: MLV + Green Glue
- For studios: Rockwool + acoustic foam
- For budget projects: Fiberglass + extra drywall
