Supporting greener public space design with car noise insulation
The design of public spaces, especially in the presence of busy traffic routes, is often based around principles of noise mitigation, with physical barriers to block engine and tyre noise. In a Masters thesis at Ball State University in Indiana, Jing Tang looks at how green infrastructure can help to achieve this, and also at […]
Higher frequencies of traffic noise prove most annoying
Many of the most prevalent frequencies in traffic noise signals overall are toward the lower end of the audible spectrum, for example the deep bass rumbles of many engines and exhausts. But newly published research indicates that it is high frequencies – such as the hiss of tyres on wet roads in the rain, for […]
Sound insulation for quiet vehicles cuts down on ‘noise events’
It is probably not a cause for much controversy to suggest sound insulation for loud vehicles in order to create less of a disturbance for fellow road users or for residents who live close to a main traffic route. But in measuring disturbances due to passing vehicles, it is not necessarily the specific volume of […]
Underbody acoustic insulation blocks reflected road noise
Vehicle underbody acoustic insulation doesn’t just help to prevent noise from the vehicle’s own transmission from escaping into the surrounding environment; coupled with floor insulation in the interior cabin, it can be instrumental in shutting out noise reflected back up from the surface of the road. This is important because, although underbody acoustic insulation is […]
Traffic noise dominates in urban environments
Traffic noise is the dominant source of acoustic and seismic noise in urban environments, according to an upcoming scientific study, with volume levels only exceeded by construction sites in isolated areas where construction activity is taking place. In an article to be published in April 2017’s Applied Acoustics, researchers at the Engineer Research and Development […]
