DB LW REG - Acoustic Attenuator

The DB LW REG Acoustic Attenuator is a high-performance sound-insulating unit engineered to lower noise generated by industrial equipment such as ventilation systems, compressors, and air ducts. Designed using a combination of Helmholtz and membrane resonator principles, it effectively suppresses airborne sound energy while maintaining airflow efficiency. This dual-technology design ensures reliable acoustic performance across a wide frequency range.

How It Works

The attenuator consists of a rigid, galvanised steel enclosure with powder-coated metal panels that house integrated sound-absorbing louvres. Each louvre combines a perforated steel surface with a sound-absorbing core, forming a hybrid resonant and absorptive system that reduces both tonal and broadband noise. The Helmholtz resonator elements target specific frequency peaks, while the membrane structure provides additional damping, ensuring optimal noise reduction without restricting airflow.

Key Benefits

• Minimises noise from HVAC systems, compressors, and industrial ducts
• Combines Helmholtz and membrane resonator technologies for maximum efficiency
• High-performance acoustic absorption and transmission loss in one compact design
• Constructed from durable galvanised steel with a powder-coated finish
• Suitable for indoor and outdoor installations in industrial and commercial environments
• Custom dimensions available for project-specific applications
• Low-maintenance construction ensures long-term reliability

Installation Overview

The DB LW REG attenuator is designed for flexible installation on air handling systems, exhaust ducts, or directly over noisy machinery. Each module connects easily to standard ductwork or equipment housings. The unit can be mounted horizontally or vertically, depending on airflow direction and site requirements. Custom sizing and mounting options are available to suit non-standard system geometries, ensuring straightforward integration into existing mechanical layouts.
