Noise Reduction Construction TRIZ Cases
- Helmholtz Resonator Array With Absorptive Foam For Broadband Acoustic Damping
A periodic Helmholtz resonator array covered with thermoplastic foam achieves broadband acoustic absorption through combined resonant and viscous mechanisms.
- Modular Soundproofing Panel With Coupled Semi-Uprights
Coupled semi-upright elements on modular panels eliminate pre-fixing requirements, reducing installation time and traffic disruptions.
- Noise Barrier Absorber With Deformable Squeeze Pads
Deformable squeeze pads clamp wall modules to strut profiles, enabling vibration decoupling while resisting dynamic stress from passing trains.
