Can you guys hear your bypass valve if you're driving with the windows up and radio off?

It has been getting cool in the mornings and on the way to work this am I got into boost and as soon as I was off the diverter valve let off a noticeable psssht - almost sounded like an open atmosphere blow off valve. Normal? Reproduced it a couple times rolling into boost and letting off. I swear I have never noticed it before (95% of my driving is windows down w/headers & exhaust blaring).
