Transport acoustics can include both the mode of vehicle being used and the infrastructure that the vehicle uses including:
– Roads
– Rail
– Air Travel
– Maritime

It can also include the surrounding environment and how the transport mode being  used can affect those in the surrounding area that includes lines of communication such as roads or rail lines.

What we assess for Infrastructure
Infrastructure refers to the facilities or structures needed for the operation of society or an enterprise (buildings, roads, rail network etc). In all cases Environmental Noise Assessments are required at planning stages to ensure that the infrastructure will not cause issues with the surrounding area. 
Depending on the infrastructure project additional criteria may need to be  met and additional information on transport planning can be found on the Government’s website

Assessing modes of transport
Testing and assessing a particular mode of transport (such as a vehicle or aircraft for example) and is normally undertaken by the manufacturer prior to it entering service as part of their own commitment to meet specific criteria required before any such vehicle or craft enters service.
Our primary services are to ensure that noise generated through the operation of such vehicles or craft do not have a negative impact on the surrounding environment.
Prior to any new roads or infrastructure projects being granted planning permission it is normal for environmental noise assessments to be carried out which we can assist with to ensure that they comply with documents such as The National Planning Policy Framework and Planning Policy Guidance 24 [Planning and Noise] (PPG24). PPG24 has been superseded by NPPF but may still be referenced to by some planning authorities.
