What Is Sound Insulation Testing?
Sound testing is done to check the level of noise attenuation performance in residential developments. This includes both impact noise (i.e., the noise produced due to impact on the surface such as footsteps) and airborne (i.e., noise transmitted through the air such as a conversation between people). It basically means that sound insulation testing is done to assess the amount of sound resistance present in a dwelling.
What Is Involved In Sound Testing?
The main purpose of sound testing is to check if the floors and walls are attenuating (i.e., reducing) an acceptable amount of noise. Part E of Building Regulations for England & Wales needs several floors and walls to be tested between adjoining dwellings. Though the exact number of walls needing testing varies depending on the overall size of the development. However, a small-to-medium building comprising of 10 or less dwellings will require sound testing that includes a couple of airborne floor tests, wall tests, and impact floor tests.
What is Sound Insulation?
The entire structure vibrates to produce the sound, which is then transmitted through floors and walls. The vibration produces new sound waves on the other side, which are of less intensity. The passage of sound from the source located in one room to the destination room, which could be another room or outside of the building is called ‘sound transmission’.
The effectiveness of a floor, door, wall, or other barriers in confining the sound passage is known as transmission loss or sound reduction index (R dB). Sound at different frequencies can vary the level of transmission loss, with higher frequencies causing higher transmission loss and it is measured in decibels (dB). The higher the transmission loss, the better a partition functions as a barrier to the passage of the annoying noise.
When it comes to sound insulation, then there are two main types, which are impact and airborne. Impact sound insulation is used for floors and is determined by the sound pressure level in the adjacent room below. Airborne sound insulation is used when the sound produced in the air is insulated and is determined by using the sound reduction index.

Airborne Sound Insulation Testing
This type of testing is done to observe the noise level in separating walls or floors. With this testing, the sound transmitted through the air is tested. To carry out the airborne testing, a specialized omnidirectional loudspeaker is placed in the source room from where the sound is produced. The specially designed speaker radiates the sound uniformly in all directions, allowing our experts to achieve accurate insulation and reverberation time measurements. A level difference is recorded in the receiving room, either directly above, adjacent, or below. This level difference is standardized to a reference value. The outcome received after airborne testing is a single number that can be compared to a performance standard.
Impact Sound Insulation Testing
This test is done along with the airborne sound insulation test. Impact sound insulation testing is performed to detect the effects of footsteps and other impacts on the floor structure.
Our team makes use of a UKAS Calibrated Tapping Machine to carry out Impact Test where the machine is kept on the floor of an upper room. The sound pressure level is recorded in the receiver room directly below the source room. There is a specific value that is taken as a reference for impact pressure level. You will get a single number as the impact result, which can be compared to the performance standard.
