The Troy "Fastlane" System of highway noise barriers has the highest Leq (equivalent continuous sound level) isolation values of any highway sound wall design. The modular barrier panel employs the sound absorption of the Troy System on the highway side in a concrete "Picture Frame" which eliminates reverberation time between parallel sound walls while maintaining isolation on the residential side.
