Part E Acoustic Testing

Why is Sound a Problem?

Sound often follows the path of least resistance, finding its way through small openings like service entry points or vibrating along nails and screws. Even when you take soundproofing measures, noise can still find a route around it! This is known as flanking transmission. When constructing your home or business, there are several common pathways for noise that you should be aware of:

• Fireplace chimneys with open flues between sound-resistant floors
• Service entry holes for plumbing pipes and wiring
• Double socket outlets on a single wall
• Unsealed mortar joints that have gaps and holes
• A lack of isolating void between ceiling boards and floor joists
• Hard floor coverings without an isolation material beneath them.

By paying attention to these potential sources of unwanted sound, you can ensure your space is as quiet and peaceful as possible.

When should my development be tested?

For optimal success during sound testing, it is beneficial to involve us as early as possible in the development process. However, there are some necessary steps that need to be taken prior to the test that can increase the likelihood of passing. To ensure you meet all requirements, here is a checklist for preparing for sound insulation testing:

• All windows and external doors must be installed, glazed and shut properly
• The ventilation system should be ready and closed off
• Internal doors should be hung correctly
• Walls, floors and ceilings should be finished
• Install skirting boards, electrical sockets and light switches where applicable
• Avoid laying any flooring before impact sound transmission tests take place
• Test rooms must remain empty and tidy throughout the procedure

Moreover , please make sure no tradespeople are working in or around either of the dwellings during acoustic testing; Access to neighbouring properties is required and both require power.
