With the continuing battle to reduce the interior and exterior noise of vehicles (the first for customer
satisfaction reasons; the second mostly driven by regulatory concerns), engineers need powerful tools to identify the
source of noise. SenSound has developed technology called
“near-field acoustic holography” that uses multiple microphones and sophisticated data
post-processing to develop multi-dimensional images of sound. Determining noise sources and paths in a complex assembly
such as a dashboard,
disc brake, or
cooling system is an extremely difficult task; technology like this should make the job a bit easier and allow vehicles
to be designed that are quieter for people both on the inside and outside of them.
