Controlling intruding noise from existing and future transport noise sources such as airports, busways, railways and roads can be very expensive. Whether it is an existing building, outdoor space or greenfield site, SoundBASE Consulting Engineers can determine the best way(s) to ameliorate transport noise. As transport noise frequently contains a large amount of low-frequency noise due to sources such as jet aircraft, heavy vehicles and diesel locomotives, we utilise noise monitoring equipment that provides the spectral composition of the noise. When coupled with our modelling software, we can optimise the acoustic design to ensure that the noise control measures are effective in meeting the design criteria without being excessive and/or unnecessarily expensive.
