Which automotive manufacturer introduced ANC into a vehicle cabin in 1992 to suppress low-frequency rumble?
Answer
Nissan in the Bluebird ARX-Z.
Following the digital breakthroughs, the application of ANC quickly expanded beyond specialized aviation headsets into mass transportation environments. In 1992, the Japanese manufacturer Nissan integrated active noise control technology into one of its passenger vehicles. Specifically, the Nissan Bluebird ARX-Z model utilized ANC to actively target and suppress the persistent, low-frequency rumble that often permeates car cabins, particularly those caused by the engine and road interaction. This adoption demonstrated the technology's viability in complex, relatively large volumes, though specialized vehicles like turboprop aircraft required even more complex multichannel systems later on.
