[Star Wars] Are the sound of the TIE fighters an intimidation strategy?

I was wondering why were they so coarse and high pitched. It would be an annoying/scary thing to hear in the battlefield. Is it intentional or was it the norm for different brand of aircraft to have different sounds?

I mean, it doesn't hurt.  But no, that was not a primary factor in selecting the engines for the TIE series.  
Also, it's a bit of a chicken-or-egg situation.  That engine whine is particularly intimidating because it means a lot of fighters are coming to kill you.  If it was coming from a civilian speeder, it wouldn't be as bad, and whatever other noise the TIE ended up making would be the scary thing.
