How Does Sound Insulation Testing Work?

If you have been asked for a sound test by Building Control and don't really know what this involves or simply want a better view on the testing procedures, this section should enlighten you on the topic.

When we carry out a Sound Insulation Test, there are a couple of different methods that we use. Both of these are effective at determining the level of sound insulation in a property. 

These methods are:
Airborne Sound Insulation Test. This involves using a loudspeaker and amplifier to create a number of different frequencies. The amount of decibels is recorded in the room containing the loudspeaker, as well as in an adjoining room. By doing this, the exact amount of noise transmitted to the next room through party walls can be measured.

Impact Sound Transmission Test. This involves using a machine which is used to bang on party floors, therefore mimicking the sound of footsteps. A sound level meter is then used to measure how much noise this creates in a neighbouring property.

While we carry out a Sound Insulation Test, we will also test the reverberation time, which is the amount of time it takes for a noise to disappear in the adjoining room. This is done using a simple sound level meter.
