WhisperStop is one brand of acoustic foam underlayment and it is 3 mm thick.
The Silencer is another acoustic foam and is fairly dense at 20 pounds of sound-absorbing material per cubic foot.
Soft flooring underlayments, regardless of physical properties, usually will advertise that they are effective against blocking sound.
Acoustic underlayments are very dense materials designed to deaden sound vibrations.
One quick way to determine density is to look at a material’s weight in relation to its size.
Felt Underlayment
Recycled felt underlayment is both eco-friendly and effective for noise reduction.
Recycled felt underlayment is about four times heavier than foam and thus is denser.
This is your best bet with engineered wood and laminate flooring.
Plywood Underlayment
Plywood underlaymentis often used under thin, flexible flooring materials like vinyl or linoleum tiles.
Plywood is only a moderately effective sound blocker.
Acoustic Underlayment
Better thanplywood underlaymentis to install specialized acoustical underlayment on thesubfloor.
The soundproofing quality of materials is often rated by their Noise Reduction Coefficient (NRC).
Thick carpeting is better for this.
Denser, higher-quality pads matter, too.
You will need to work around obstacles, like electrical wires and recessed lights that extend into the ceiling.
Finally, new ceiling drywall is installed.
The joists act as acoustic bridges to transmit the sound.
To truly block sound, you better separate the surfaces.
