Reduce Impact Noise
Impact noise is the transmission of sound via the interaction of different materials to each other i.e. Footsteps on the floor of a house if there is lots of noise being produced from above you. This noise, commonly known as “Transmission Noise” is one of the hardest to stop.
Impact Noise Causes
Impact noise from a ceiling is generally caused by people running, jumping and dropping objects on the floor above your home or apartment. This won’t just effect one room, but will probably spread to multiple rooms or even your whole house. Impact or “Transmission Noise” will be the strongest as it moves through the floor. When traveling it will slowly lose energy and reduce in sound. This is the most difficult type of noise to stop due to the different ways it travels and comes through your ceiling.
With impact noise, every treatment is different. We find different homes experience different impact noises due to the way the home was built. Due to many different techniques and materials used in the construction of the property. It is known that metal studs have less transmission noise than wooden studs. A home with wooden studs compared to metal studs have a higher chance of transmission noise getting to other rooms and traveling further than a home with metal studs.
The vibration of the impact noise causes the noise to travel through the ceiling and walls. Although installing ceiling soundproofing will absorb a high percentage of the noise at the source, we may also need to look at treating the walls and floors as well.
To reduce impact noise and vibration transmission you need to either stop the sound getting into the floor, out of the ceiling or a combination of both, by adding a Floating Floor or an Acoustic ceiling system.
