Question 2011 subaru impreza wrx hissing noise?

I just bought a 2011 wrx sedan and when I leave the car sit and idle once in a while it makes a hissing like spray noise is it normal or could there be something wrong?

Could be the intake. I would check for any intake related leaks.

Yep, this is normal. I had it happen on my 11 wrx and current car.

Sounds more like to me that it's the A/C compressor cycling on and off.

Check for snakes inside the cabin. You might have an infestation.
