Carpet Floor Noise Reduction. Heavy and dense with a good STC of 27. I also discovered another solution for absorbing noise between apartment floors requiring installation.
440 Homasote is a dense cellulose fiberboard designed to be installed under carpet to reduce sound transmission rated for a noise reduction coefficient of 020 If you happen to own an upstairs unit or can convince your landlord to split the costs this material could be an effective long term solution. Carpet is usually the cheapest option in the short run. This dissipates the impact energy before it has a chance to enter the building structure as sound.
For really piercing noise from playing instruments like loud drums or throwing heavy objects on the floor in case of weightlifting for example using acoustic underlays within the sub-flooring would probably be a good thing.
Consider it a gift to your neighbours. Quality product made from extruded virgin material. Carpeted floors can result in a reduction in noise of over 20 decibels This is particularly important in schools busy offices health care facilities and in the home with children where floor impact sounds can contribute greatly to ambient noise levels. Carpeting alone is helpful in reducing footfall noise but it cant compete with airborne noise transmission through the floor.
