Hearing sound in a space

Could you send a jet of a gas a short distance through the vacuum and include a (very simple) sound as a modulation in the amount ejected? What gets to the astronaut has a lot less gas - but what there is is in a series of pulses which the helmet would pick up as sound

Possible, I suppose but one has to consider just how quickly the gas will diffuse. For a room temperature gas, the rms speed of the molecules is quite large, around 500 m/s for N2
