I have a 1950s vintage 2-story building with no insulation. The second floor
is hardwood and transmits clicking, echo footstep sound to the floor below.
Below the hardwood floor is wood underlayment, wood joist and finished with
a plaster ceiling, no insulation. I want to install a laminate flooring on
top of the hardwood flooring (I could go carpet but prefer not to) so what
is my options in soundproofing the floor for the DIYer. Any products that
really work?

Many sound-control underlays can be installed easily by the
do-it-yourselfer.

The relative performance of sound control underlays can be determined
with standardized testing methods.

The Sound Transmission Class (STC) is a rating of how well an underlay
reduces airborne sounds such as conversation. The STC rating is based
on testing in a laboratory, and the Field Sound Transmission Class
(FSTC) rating is based on testing in a real-life environment.
The Impact Insulation Class (IIC) is a rating of how well an underlay
reduces impact sounds such as footsteps. The IIC rating is based on
testing in a laboratory, and the Field Impact Insulation Class rating
(FIIC) is based on testing in a real-life environment.

The higher the ratings on comparable floor assemblies, the better the
underlay reduces sound transmission.

Superior (and more costly) underlays tend to have values in the high
50's and up.

You should be some relief using the deluxe padding for the new floor.
The bad part is you will not know until it is done. The fix if that does
not do it is to put a new ceiling in below secured to isolation fixtures .

This you can do after you are done with the new floor just as easy as
before.
