When addressing noise control challenges, acoustic blankets are just the beginning. Different noise sources require different approaches — high-frequency equipment noise demands different treatment than low-frequency industrial rumble, and temporary construction sites have different requirements than permanent industrial installations.
Successful noise management requires understanding the full spectrum of available solutions and selecting the right combination. At Environmental Noise Control, we have developed a comprehensive range of noise control products that extend far beyond basic soundproof blankets, providing engineered solutions for complex acoustic challenges across multiple industries.

Key Acoustic Terms Glossary
But first, understanding noise control terminology will help you make informed decisions about your acoustic needs:
- STC (Sound Transmission Class): A single-number rating that measures how well a material blocks sound from passing through it.
- NRC (Noise Reduction Coefficient): Measures how much sound a material absorbs rather than reflects.
- ASTM E-90 and ASTM E-413: Standardized laboratory testing methods for measuring sound transmission loss through building materials. This ensures consistent, reliable performance data across different manufacturers.
- UBC/IBC Wind Load Requirements: Building code standards that ensure structures can safely withstand wind forces. All ENC barriers are engineered to meet these safety requirements.
Temporary Sound Walls
Available in various heights and ideal for use in:
- Construction sites requiring perimeter noise control
- Temporary industrial facility barriers
- Projects needing traditional ground-mounted installations
- Applications requiring maximum structural stability
Dual STC Rating Options available in STC-25 and STC-32 ratings, allowing you to select the exact performance level your application requires.
NRC Overlay Capability to provide both noise blocking and absorption, reducing sound reflection for better overall acoustic control.
