Acoustic barriers are essential products designed to minimize airborne noise and impact sounds. They play a significant role in soundproofing by preventing transmission loss and reducing vibrations. Whether used in vehicles, industrial settings, or residential spaces, these barrier products effectively enhance acoustic performance.
By combining flexibility, vibration dampening, and thermal insulation, acoustic barriers provide a comprehensive solution for noise control across multiple industries. This article explores how these barriers work, their benefits, and their various applications.
How Do Acoustic Barriers Work?
Acoustic barriers function by absorbing and blocking sound waves, preventing their transmission from one area to another. Their effectiveness depends on various factors, including material composition, thickness, and installation method. Here’s how they work:
- Absorption of Sound Waves – Some acoustic barriers are combined with foams to absorb sound waves, reducing echoes and background noise.
- Vibration Dampening – The material’s flexibility allows it to reduce vibrations, minimizing structural noise in metal and plastic surfaces.
- Thermal and Sound Insulation – Certain barrier products reflect thermal radiation while also preventing noise transmission, making them ideal for industrial applications.
- Adhesion to Surfaces – These barriers can be applied to flat, curved, and even wavy surfaces, ensuring a custom fit for different applications.
Types of Acoustic Barrier Products
Different barrier products are available to meet various soundproofing needs. The most common types include:
1. Polymeric Acoustic Barriers
- These are low-density vinyl membranes loaded with natural materials.
- They enhance sound insulation in metal, wood, and plastic panels.
- They are free from lead, aromatic oils, and bitumen, making them environmentally friendly.
2. Bitumen PE Foil Covered Barriers
- These feature a black PE-faced barrier with a self-adhesive backing.
- Ideal for flat sound insulation, vibration dampening, and noise reduction.
- The PE foil prevents oil seepage, keeping installations clean.
3. Bitumen Aluminium Acoustic Barriers
- Made from a dense mixture of bitumen, polymers, and mineral fillers.
- Features an aluminium foil surface, making it heat-resistant.
- Commonly used in engine blocks of cars, construction vehicles, and marine industries.
