The way I get around sound is space is this; Our ships have sensors (such as RADAR, thermal pickups, radio, and so on), but we mere humans cannot 'see' these, so the various ship (and equipment) manufacturers have designed ways for the sensors to present their data in clear, simple ways for us to understand. If, for example, an Asp Explorer approaches me my ship will (using accurate audio placement and audio effects) inform me where that Asp Explorer is coming from (and, by the distinctive 'engine noise', what type of ship it is). When we are in Super Cruise (and, therefore, travelling faster than light) our ships visually shows us where the astronomical objects are by detecting them via graviton particles and then translating that information into optical frequencies our eyes can pick up (and, if we are close enough, audio frequencies our ears can hear).
This already exists (slightly) in Real Life. You and I cannot see Infra Red light. However, if you use a decent digital camera (the one on a typical smart phone will do), line up a remote control on the lens (while you are looking at the camera screen) and then press a button on the remote control, you will see a flashing purplish light. This is the IR led, translated into light frequencies humans can see by the technology of the camera.
