- Additional information
- For the proposed UK High-Speed rail 2 (HS2), the sound pressure level at high speed will be around 128 dBA (500-5000 Hz). Owing to a steep rise in urban population, there has been a continuous growth in construction where new sound attenuation technologies are being experimented on for HS2 noise attenuation. Funded by the Department for Transport (DfT), this research developed a new frequency depending passive waveguide named Herschel–Quincke-Arjunan (HQA) capable of passive sound cancellation. HQA is one of the few approaches suitable for frequency controlled high-efficiency noise attenuation that can be incorporated in common building material.
