Once again, mass rules. But also there is a technique known as the 'floating floor', which is widely used in studio construction.
The fully engineered floating floor would consist of a concrete slab formed on metal shuttering, supported on rubber pads or even heavy-duty springs.
The mass of the slab is important as the mass-spring system will have a resonant frequency, at which the sound insulation properties will be worse than if the floor were not floating!
A massive slab can push this resonant frequency below the audio band.
Where restriction on cost or loading prevents a heavy floating floor, a lighter-weight version can be constructed to BBC recommendations by putting down a resilient layer of high-density mineral wool (approximately 30 mm) covered with a plastic sheet, and then laying a 70 mm reinforced concrete slab on top of that, with a further 40 mm concrete screed on top.
A wooden domestic floor may be improved by adding two layers of 18 mm particle board on top, with the joints staggered to avoid gaps.
The gaps around the edges can be filled with a mastic material, or by compressing mineral wool tightly into the gaps.
There would be no harm in 'floating' this on top of an old carpet, but the additional benefit, other than for impact noise, would be slight.Come on the FREE COURSE TOUR
This course covers the principles of MIDI, synthesis and sampling that can be applied in any DAW, any synthesizer, and any sampler.The course covers principles that can be applied to all DAWs, synthesizers and samplers so that students can work comfortably with any software or hardware with such functions.

Students are given a series of professionally produced multitrack recordings and are asked to replace certain instruments or vocals. In some assignments we ask for a replacement that is close in sound texture and performance to the original. In others we encourage the student to apply a high degree of creativity. Learn more...
The course adds twelve further practical assignment projects covering topics from drums, through acoustic guitars, electric guitars, bass guitar, vocals, background vocals, keyboard and synthesizer arrangement, production and recording. The practical assignment projects work through the imitation of sections of recordings that have had great commercial success. Learn more...
