BMW boasts of having 100 “acoustic engineers” on its books. Their work means that the BMW 7 Series saloon whispers along in a vacuum, the driver worried about having gone deaf. At traffic lights, only a furtive glance at the rev counter tells you that the engine hasn’t died. By contrast, the Z4 is motor-din heaven. Like a decent audio system, the car’s engine sound management system has been tuned to get the most out of the motor. Noise from the engine is fed into the cabin, with intake system pressure noises from the intake manifold, instead of being killed off with yards of felt matting. It arrives in the cabin via a tube and a flexing diaphragm. The result is a high-octane backing track.

Airbox. Where the pressurized air accumulates before it either gets sucked into bellmouths of carbuerators or the venturi of fuel injection. Alot of sound tuning above the throttle bodies these days. Heard about it at the BMW 1K and the new Z1K launches.

Usually it is a growl. Kawasakis over the last 10-15 years are especially known for lots of intake noise.
