Impact Sound Insulation Of Floors

The product series acoustic floor mat afm acoustic floor blocks afb and the material sylomer offer effective insulation and customised sound control for a wide range of applications and achieve impact noise improvements of up to 37 db.

Impact sound insulation of floors.

For each floor assembly irc measured the impact noise level and calculated a rating called the impact insulation class iic. Impact sound is the sound of impact on a floor surface like the sound of footsteps on the floor above. We have already written an article elsewhere on the subject of impact sound insulation for vinyl floors. As with airborne sound these vibrations pass throughout the structure before being re emitted in other areas.

Therefore the increase in impact time is related to the elastic characteristics of the floor coating which reduces the excitation spectrum to be irradiated by the structural slab. For impact sound insulation di er from standard ones especially in the range of the 2 khz frequency which is 22 db higher than the iso reference curve. Four natural impact sounds basketball bouncing chair moving walking with shoes walking with socks were presented to the floors and recorded in the furnished room underneath. Alternative reference curves were presented and analyzed.

He concluded that it is possible to obtain. The results of the test are rated in terms of the impact insulation class iic. Impact insulation class or iic is a rating of impact sound insulation. Impact sound comes primarily from footsteps and it s here that bare floorboards or laminate flooring cause problems as carpets and underlay contribute a lot to reducing these impacts.

Unlike airborne sound though the regulations regarding impact sound are typically only concerned with sound transmission between the floors of a building. The normalised floor impact sound levels were 53 8 55 0 51 3 46 3 and 35 6 db for 125 250 500 1000 and 200 hz respectively. Of impact sound that can be achieved with different types of floor assemblies. Four floating floors and two non floating floors were built in a laboratory where the impact sound insulation was tested using tapping machine and rubber ball.

The higher the iic the better the attenuation of impact sound with 50 usually considered the minimum rating for occupant satisfaction. In that case impact sound reduction is a consequence of the increased time of impact due to the characteristics of the elastic material 2. It only applies to sound transmitted down through a floor and ceiling. The impact sound insulation properties of a floor ceiling structure including the flooring are usually tested by measuring the transmitted sound in a room below while a standard hammer machine bangs on the floor above.

It does not apply to walls. Your advantages with sound control from getzner excellent impact sound insulation for any floor structure.
