Normally it is thought that a finished basement is extremely difficult to deal with when you are trying to soundproof it but the reality is different. The choice is yours whether you want to do it yourself or you want professional help. All you need for it is soundproofing material and a resilient channel.

A resilient channel is a metal channel that is extremely useful for enhancing sound insulation. This channel is really good in disassociating the ceiling from the framing stud work that ultimately reduces the noise.

It is possible because there is proper space between the existing ceiling and the new one you are creating. If there is any space likes air vents you have to fill them with the sound damping material as well. Once you have installed the channels with the help of clips according to the dimensions of your structure you have to install drywall onto the channel. Make sure that the drywall is also made of special soundproofing material.

Try to create air space between each layer and create as many layers as you can so you would be able to tackle the noise in a better way.

If all the above-explained solutions do not work you may need drywall insulation and a resilient channel. It would cost you a bit but nothing is precious than your peace of mind. We will explain the complete process in a simple manner.

This works really well for the finished ceiling of the basement. The resilient channel would support the drywall to take the benefit of the extra layer of the air space. Apply special glue for dealing with the drywall that can be purchased from any market. The glue has to be applied to the edges of the drywall as well. Use at least 3 layers of drywall to get the best results.

Use screws to attach the second and third layers of the drywall with the first one beneath the ceiling. This would create enough airspace between the ceiling and the ground surface to avoid any kind of sound. You also need to seal the whole area and all the cracks or space with the help of soundproofing glue or compound that are also available in the market.

There can be unattended spaces or gaps due to the vents and you have to deal with them as well. You can utilize sound damping foam to fill the vents and the spaces in order to block the maximum amount of space in this situation. This solution would definitely reduce the chances of noise reaching the basement surface.
