Soundproofing Insulation Info


If you have ever experienced uncontrolled or unwanted sound in your home, recording studio, school or work place then you will know how annoying it can be and the need for such places to have soundproofing in place. Apart from getting on your nerves, noises can lead to serious health hazard (cause damage to your ear drum),especially sounds with high-frequency and high-intensity. This is as a result of the force and number of sound waves transmitted by such sounds. Even the slightest adjustment to the level of decibel (used in measuring sound level) can significantly affect the sound you hear.

Most of us find ourselves living in noisy environments and more often than not, we find it very frustrating living in such environments. Consequently, this has prompted so many into looking for ways to avoid the noise. The big question therefore is, how can you control the sound you hear? As pretty straightforward as this question may seem, it has however posed a big challenge to many over the years.

Sound Insulation Testing Explained

One of the many Building Regulations requirements when developing residential properties is to achieve a certain standard of sound insulation performance between dwellings.

The specific performance requirements for new builds and conversions are set within Approved Document E (2003 Edition) and are summarised in the following tables.

New Builds
Airborne Sound Insulation (DnT,w + Ctr) ≥ 45 dB
Impact Sound Insulation (L’nT,W) for floors only ≤ 62 dB
Airborne Sound Insulation (DnT,w + Ctr) ≥ 43 dB
Impact Sound Insulation (L’nT,W) for floors only ≤ 64 dB

What They All Mean

The whole purpose of the new  regulation is to provide adequate sound insulation between neighbouring properties when converting a single dwelling property into one or more separate dwellings.

Applies both to party walls and floors. This level is, simply put, the difference between the source level and the receiver level during sound insulation tests. For example, if the source level in one flat is 100db and the receiver level in the neighbouring flat is 45db, the level difference (or sound reduction performance) is 55db. This difference is then corrected for several factors such as background noise, room characteristics and frequency weighting (which we will not dwell on),giving the final sound insulation performance value of the tested element. So, the higher this number, the better the performance.

Now, the impact insulation performance values shown only apply to party floors and related to the effectiveness of the floor construction in absorbing shock, hence not transmitting footfall noise. The measurement is done by using a tapping machine which has 5 weights tapping in regular succession on the tested floor. The noise levels in the room below are then measured and averaged for different tapper positions, giving the sound reduction rating of the floor. So, in this case, the lower the figure, the better the performance.
