The move towards electrification has brought with it some unfortunate consequences, not least the slow death of the exhaust note.

Porsche seems to be keenly aware of this and wants to bring the noise back, or at least stop it from going away, with its future electric vehicles.

According to Carbuzz, the German manufacturer has filed a patent with the European Patent Office for a resonator which it hopes will mimic the noise of an internal combustion engine.

While it’s not a direct replacement for the aural symphony that comes out of the exhaust of something like a 911 GT3’s flat-six, the patents show a noise simulator within which looks to be the rear muffler of one of its sportscars – pumping synthetic noise into an existing design.

Likely constructed of the same materials as its existing back-boxes, the adoption of a resonator such as this one could result in Porsche circumventing the need for the traditional warning systems found on EVs, the majority of which do anything but replicate the noise of a combustion engine.

It’s unknown whether Porsche has actually started to develop such a system, or if the patent submission is purely to head off competitors coming up with similar systems.
