Road noise is a common complaint amongst car buyers, and manufacturers have been fighting it in a variety of ways for years. For the first time in a long time, there’s a new, exciting solution to this issue, thanks to Nissan.
At this year’s CES, Nissan unveiled their solution to this noise problem that has been annoying people for years. Their solution comes in the form of a lattice structure and a plastic film which is used to control air vibrations and limit sounds entering the cabin. The range at which this system could block noise would be from 500 to 1200 hertz and would include road and engine sounds.
The auto industry has attempted to create a solution for this noise problem in the form of heavy rubber, but this solution has a major flaw. The rubber adds unnecessary weight. Nissan’s system of a lattice structure and plastic film weighs significantly less, and also performs its noise canceling task much more efficiently.
The official name for this noise canceling system is “acoustic meta-material”, and it has been continuously researched since 2008, but it is now ready to be considered for use in noise cancelling situations!
