Damped Mode Attenuation
Damped Mode Attenuation provides targeted control of fan noise without introducing additional pressure drop. Unlike conventional splitters or resistive elements, the technology is tuned to the acoustic ‘signature’ of the fan itself, delivering attenuation exactly where it is most needed.
Developed through analytical, numerical and experimental research, this approach suppresses the dominant duct modes while maintaining a clear airflow path. A patent application is in progress.
Dynamic insertion-loss tests have shown that the absence of flow resistance results in a 20% reduction in specific fan power. The attenuator is also 35% shorter and around one-third the weight of an equivalent splitter solution while offering comparable insertion loss.
Potential applications extend beyond HVAC to compact consumer devices such as hair dryers, hand dryers, vacuum cleaners and natural ventilation systems.
