Noise pollution or ambient game noise?
If it's noise pollution, you won't have to worry about the industrial zone. They are noise and ground polluters and the businesses there are immune to the effects.

Residential zone and the cims living there are vulnerable to noise pollution and it is there that you should keep noise to a minimum.
Use tree lined streets for noise reduction.
Avoid zoning residential within the noise radius of known noise polluters. This would obviously mean you should not zone residential and commercial (commercial is a noise polluter) adjacent to each other, nor should you place a metro in a residential neighbourhood.
If you have kept your residential clear of noise polluters, then the only other factor to bear in mind will be traffic noise.
To avoid this, try not to zone residential along your main arterial roads. Especially avoid routing your freight deliveries through residential zones - another reason why you shouldn't zone commercial and residential together.
Try to use other non noise polluting structures such as parks and services or zone offices as buffers between your residential zones and commercial or industry.
Hope that helps ;)
