Featured Projects

EKHO R&D team designed and completed successful bend testing to assess the strength of Durisol’s newest 20 ft double-sided absorptive noise barrier panel

Two-sided absorptive noise barrier panel designed for spans of 20ft

Our EKHO R&D team designed and completed successful bend testing to assess the strength of Durisol’s newest 20 ft double-sided absorptive noise barrier panel.

The NB20 system is a 4’ tall precast panel noise barrier system with bay spacings 20’ on center, allowing for installation efficiencies where site conditions require long straight runs with minimal grade changes.

Presentations & Papers

NOISE-CON 2024

Presenter: Gary Figallo 

Gary presented on reducing targeted low frequency railway noise with precast modular sound absorbers.

Key Takeaways:

  • High-speed trains operating on concrete guideway propagate noise from the wheel/rail interface, low frequency aerodynamic noise from the wheel region including the bogie and reflections from the reverberant area underside of the vehicle.
  • Abatement of these sources is enhanced by placement of broadband sound absorbers close to the rail, between the rails and adjacent to the track. High absorption coefficients of 0.80 to 1.00 from 160 Hz to 5,000 Hz span the most important frequencies of interest to reduce environment wayside noise.
  • It is particularly beneficial in a tunnel or in a station to have installed a product that has broadband absorption coefficients.
  • In urban environments, LRV noise abatement can be achieved by reducing reflected noise from a concrete guideway.
