NoiseTrap Panel
Weighted sound reduction up to Rw = 44 dB
Weighted sound absorption up to α = 1.00
Absorption based on metamaterial principle
Our NoiseTrap Panel is an acoustic element that forms a modular system designed to reduce low-frequency noise using patented metamaterial resonator technology. The panels are made entirely of galvanised steel without acoustic infill, making them ideal for sensitive environments such as hospitals and food production facilities.
The system can be supplied as self-supporting units or mounted on steel frames. Its modular design allows easy integration of walls, access doors, and ventilation openings, while panels can be temporarily removed for maintenance without compromising acoustic performance.
NoiseTrap Panels are customisable to the customer’s site requirements and available in four variants:
- LF150 – 150 mm deep, 42 kg/m²
- LF250 – 250 mm deep, 60 kg/m²
- LF250A – 250 mm deep, ventilated, 48 kg/m²
- LF450A – 450 mm deep, ventilated, 67 kg/m²
Panels can be installed as self-supporting units or on steel frames for larger spans. They provide sound insulation values of up to Rw = 44 dB and are manufactured entirely from galvanised steel. They are rain-resistant and designed for long-term performance without acoustic infill.
NoiseTrap panels are ideal for industrial noise control around transformers, steam or gas turbines, compressors, pumps, combustion engines, and generators. They can be used for permanent enclosures or movable partitions and can be equipped with passive ventilation, acoustic doors and windows, and steel frames for complete enclosures.

Answers to common questions
The lifespan depends on the application and environment, but Merford panels are designed for decades of use in industrial and HVAC settings. Materials such as galvanized or stainless steel and moisture-resistant acoustic fillings ensure consistent performance, even under fluctuating temperatures and humidity.
Yes. The modular panels can be quickly assembled, disassembled, and relocated, making them suitable for temporary enclosures, test setups, or reconfigurable industrial spaces. This provides flexibility for renovation projects or changing production environments.
Merford's modular systems are optimized depending on type: the NoiseTrap® Panel and Blox are specifically designed for enhanced low-frequency attenuation, while SKW provides improved low-to-mid frequency performance due to a higher mass. Our SKS, MSK and G14EP systems primarily provide effective attenuation in the mid-to-high frequency range, with performance gradually decreasing toward lower frequencies.
Yes, the modular design makes it possible, for example, to integrate NoiseTrap® Panels with SKS or MSK walls. This allows airflow management and structural sound insulation to be combined in a single installation, provided that installation sequence and air passage are properly considered.
