skoda octavia hatchback - wind noise - jelly

I have a 1.6 skoda hatchback, there appears to be alot of noise even when just driving urban, no motorway driving yet. My visual examination of the car has resulted in nothing out of the ordinary, any suggestions?

Be good if you can give us a little more to go on!!

First thing to do is make sure you're driving with windows, doors and sunroof fully shut.

Listen for where the sound is coming from, then inspect all the seals in that area.

Get someone else to drive and use a stethoscope to pinpoint the noise. Alternatively shut the car with the stereo on and use the stethoscope from outside.

Hi Cyd{P}
Sorry for lack of detail re noise. It's difficult to describe. Basically it is a hollow sound as if the noise is circulating within the car. It's like a whirring sound as if in a wind tunnel. I have inspected the window seals and ensured all doors and boot firmly closed. I have noticed that altough all 4 tyres are same size etc, they are different makes, not sure if this is significant. Have had several passengers in the car and no ideas from them re noise.
