Underlayment Sound Protection

Could you please tell me the best underlayment for impact sound protection from the first floor to living space below? The floor will be a combination of tile and engineered wood. I am trying to find the best product while keeping cost down on both materials & labor. There will only be 2 people in the house—no children or pets. I have looked at SoundStop, SolidBlack MD and QTscu (Ecore), but no real life feedback on any of these.

Thank you

 

For the tiled areas (you might use it under the engineered wood too, don't know - have to read the spec sheet), you might try EasyMat from www.custombuildingproducts.com. The thicker versions add more sound isloation so you can buy the amount you want to pay for.
