The most common question we are asked is “How do I soundproof my walls to ensure I pass my Part E sound test?”. You are in the right place as we can guide you through this process with ease, we have numerous designs we can provide and can also discuss bespoke solutions for soundproofing walls. Firstly, as a developer you need to consider what acoustic performance you need from the party wall. We can design soundproofing for your wall to just pass a Part E sound test or we can design soundproofing for your walls to achieve an excellent level of sound insulation compared to Part E’s minimum requirements.
Does Part E of the building regs apply? Whether Part E of the Building Regulations applies depends on whether the HMO is defined as rooms for residential purposes. The building regulations Part E states;
If you are involved in the construction industry then you will know the importance of meeting all building regulations.
Sound travels through buildings in different ways, by both airborne sound and structure-borne sound. One form of structure-borne sound is known as impact sound.
Flanking and indirect sounds move from room to room and travel indirectly over or around a soundproof element. A common occurrence of flanking is when sound is transmitted through a floor, beyond a separate partition despite the fact that the partition may provide good sound insulation to prevent sounds that are directly transmitted.
When designing buildings, there are different types of sounds that should be considered when thinking about sound insulation. One of those types of sounds is airborne sound, which is sound that travels through the air.
Sound insulation is the reduction in sound experienced across a partition, such as a dividing wall between offices or rooms in a house or flat. Suitable sound insulation is incredibly important regardless of the building type for privacy and to ensure that the construction meets all of the relevant Building Regulations.
Sound absorption refers to the loss of sound energy when sound waves hit ceilings, walls and floors, and they are absorbed. Materials that are absorbent are often used so that a particular building is soundproofed to reduce the amount of reverberation, which has an impact on the way a particular room sounds.
Resilient bars allow secure fixing of plasterboard or other boards to timber joints while improving the acoustic insulation of walls or ceilings. When properly installed, they allow the wall or ceiling to flex slightly, which absorbs sound.
In today's open plan living the need for sound insulation has become increasingly important. There are many complex elements that are involved in the soundproofing of a building. All of these elements work together to help reduce noise and vibrations.
