Airplane, train and carcabin sounds.

The inside of a plane, a train or a car at night has a low, enclosed drone. Walls and windows block high frequencies far better than low ones, which leaves a deep sound close to brown noise.

The inside of a plane, train or car sounds deep because walls and windows block high frequencies much better than low ones. What reaches you is mostly the low rumble of engines and wheels, close in shape to brown noise.

Why cabins sound so deep

Insulation, glass and panels stop high frequencies much more easily than low ones. What reaches you is mostly the rumble of engines, wheels and moving air, with the hiss filtered away.
