Envirotech Noise Barrier is a specially designed structure that limits the spread of sound from its source to surrounding areas. It acts as a physical obstruction that reduces noise reaching residential, commercial, and sensitive zones. It works by interrupting the path of sound waves, thereby lowering the level of noise that reaches people and buildings. By forming a solid shield between the source and the receiver, a noise barrier helps protect residential zones, commercial spaces, and noise-sensitive locations such as hospitals, schools, and offices.
Noise Barriers are widely installed alongside roads, highways, railway tracks, metro corridors, industrial facilities, power plants, and construction zones where continuous noise is generated. They help control sound produced by traffic movement, heavy equipment, and industrial operations.
Manufactured using materials like metal panels, concrete, or transparent sheets, noise barriers are designed according to site-specific acoustic and structural requirements. Their proper installation improves environmental comfort, supports regulatory compliance, and contributes to healthier and quieter surroundings in modern urban and industrial settings.
How Noise Barriers Reduce Sound
Noise barriers work through a combination of acoustic principles:
- Blocking Sound Transmission: Dense barrier panels prevent sound waves from traveling directly to nearby areas.
- Absorbing Noise Energy: Sound-absorbing layers reduce reflections and echoes.
- Optimized Design: Proper height, thickness, and positioning improve overall noise reduction performance.
An effectively designed noise barrier can significantly lower noise levels when installed correctly.
Types of Noise Barriers
Different environments require different noise control solutions. Common types include:
- Highway Noise Barriers: Highway / Road Noise Barriers are installed along roads, expressways, and flyovers to reduce traffic noise affecting nearby residential and commercial areas. These barriers help control sound generated by vehicles, horns, and tire friction.
- Railway Noise Barriers: Railway Noise Barriers are used along railway tracks and metro corridors to control rolling noise, vibration, and braking sounds from trains. These barriers are designed to withstand high wind loads and vibrations.
- Temporary Noise Barriers: Temporary Noise Barriers are used at construction sites, road repair zones, and short-term projects. These barriers are easy to install, relocate, and remove after project completion.
- Metallic Noise Barrier: A Metallic Noise Barrier is a noise control structure made using metal panels such as galvanized steel or aluminum, combined with sound-absorbing materials. It is designed to block, reflect, and absorb sound waves generated by traffic, trains, or industrial machinery, thereby reducing noise levels in nearby areas.
- Polycarbonate Noise Barrier: A Polycarbonate Noise Barrier is a transparent or semi-transparent noise control system made using high-impact polycarbonate panels. It reduces the transmission of sound from traffic, railways, and industrial sources while preserving the surrounding view. Due to its strength and clarity, polycarbonate is an ideal alternative to solid noise barrier panels.
