sound radar is back ... naaaaaaah!

Just a further thought, when driving at say 110kmh on the open road (in a sound proofed vehicle)I can't hear say a fast moving Harley Davidson until it passes(I usually warn my wife and kids of its approach). But if the same bike gets caught behind me and matches my speed then I can hear him. So maybe approach speed also needs to be taken into account?

At same speed there would be no approach.

Again, your audio apparently supersense is imho not necessarily a good basis for comparison

And then a car or a bike at 110 is barely comparible to a fighter plane that flies at much higher speeds and with much more hp ...

A plane engine is also not at the same frequency band and don't forget the bandwidth audible by the normal mortal human being is limited ...

Obviously no point in a debate.

Well to hve a debate you hve first to hear each other. Can you ?

For a team to succeed they must first learn everyone opinion is valuable and must be taken into account. To just flatly disagree and shut down other peoples suggestions is a quick road to failure.

Sorry not aimed at you Tomcat. I can take a joke, just not so good at criticism it would appear
