Yes, soundproofing your home can be life changing and for many of our clients it’s one of their best investments they make. However how do you know it will work?


Our credential’s:

  • YouTube channel with videos showing before & after soundproofing
  • Article in the Sunday Times
  • Blogs with case studies offering plenty of advice
  • #1 Amazon Best Seller book; The Noise Free Home, available on Amazon, WH Smiths and Waterstones
  • Published UKAS test data of actual homes (not a clever box trick)
  • Numerous awards including UK Innovation & Excellence award
  • 1,000s of happy customers
  • We give you 50 homeowners contact details who have soundproofed their home with Quietco
  • We use the highest quality materials on the market
  • We have tested our products at institutes like Birmingham University
  • We have a four step soundproofing method ensuring nothing is missed
  • We care and are passionate about solving your noise problem

We have some videos on our YouTube channel showing the soundproofing result and some before and after videos, but filming the soundproofing result is actually very difficult.

How do you capture a before and after soundproofing result?

The soundproofing between houses using our four step soundproofing method results in an amazing sound reduction and most airborne noise is difficult to hear or capture on video. Various impact noises can still be heard but so muffled that they are again difficult to capture on film.

If you have any ideas or experience in filming before and after results please get in touch.

Percentage Noise Reduction Example



Decibels: A decibel (dB) measures how loud a noise is.

50dB is quiet while 140dB is so loud it can immediately injure your ears.

Case Study

The level of sound prevented from transmitting through separating walls and floors is measured (airborne sound insulation), and the higher the figure the better (the regulations require a score of at least 45dB DnT,w + Ctr). The testing covers a wide range of frequencies, but unfortunately takes the average of the room.

An amazing wall system on the party wall might achieve 70dB DnT,w + Ctr but if you have not treated the suspended floor void, the ceiling void or other holes in the structure, these would let neighbour noise through.

If the sound test found the overall sound insulation average of the room to be 50dB DnT,w + Ctr, which is a pass, you might still be able to make out words and follow conversations from next door.

The acoustic test came into force on 1 July 2003 for refurbishment projects.

To give you an idea what 45dB DnT,w + Ctr means in real life, in a 1950s three-bedroom semi-detached house, Quietco paid an independent company to carry out a UKAS-accredited sound insulation test of the separating party wall before any soundproofing was installed.

The sound insulation value of this wall measured at 47dB DnT,w + Ctr, 2dB higher than the building regulations require for new dwellings, so better sound insulation than the standard required for properties newly built today.

However, we stood in our client’s neighbours’ dining room, the other side of the party wall, and managed to turn on our client’s smart speaker.

After soundproofing using the four-step method, we achieved 62dB DnT,w + Ctr; this is a 15dB reduction in noise from next door.

This is a 139.61% reduction in pressure level of sound from next door.

The calculation is as follows:

(A) 62dB = 0.0251785 Pa (pascals – measure of sound pressure)

(B) 47dB = 0.00447744 Pa

Change % = 100 × (A – B)/((A + B)/2)
= 100 × (0.0251785 – 0.00447744)/

((0.0251785 + 0.00447744)/2) = 100 × 0.0207/(0.02966/2)
= 100 × 1.39608
= 139.61%

That gives a 139.61% change in pressure level of sound.

10db is a halving of sound as we hear it, so the 15dB reduction represents a significant reduction.

So… will the soundproofing work?

Yes absolutely, follow the four step soundproofing method and you will get a significant reduction in noise, like our clients.

We give you a page of 50 homeowners with their contact numbers, they have all gone through the same decision process. You can phone them up and speak with them if you choose….maybe ask them yourself.

If you have a noise problem, the first step is to fill out the form and book yourself a free noise diagnosis. If you are not within our installation area we can still help you with consultation advice.
