The noises that we were dealing with were both structure-borne and air-borne, the source of which was a Cold Water Pump Room with an air conditioning
duct on Level 40 and a Hot Water Pump Room with boilers on Level 41.
The noises heard were a mixture between a low pitched hum / vibration noise (both air-borne and structure-borne – source Level 41) heard within
the immediately adjoining spaces on Level 41 to a higher pitched rattle / ringing noise (structure-borne only – source Level 40) heard
throughout ALL the nearby spaces across Levels 39-42.
After analysing the noise spectrum with the Megasorber 4-fold approach,
Megasorber engineers put forward the following soundproofing proposal:
- Line the internal walls and ceiling of the plant room with Megasorber P100, a 100mm thick acoustic panel with a water repellent, fireproof and sound absorbing
Soundmesh G8 facing.
- Install the Megasorber P100 onto the concrete wall with Megasorber A200 adhesive and seal joins with colour matching Soundmesh G8 tape.
- Apply Megasorber D14,
a self-adhesive vibration damping sheet, onto the metal duct works and metal pales on the plant equipment.

Dealing with Megasorber was an easy, professional and very helpful experience all the way through. I am really satisfied with the product,
it has most definitely achieved the goal that I was after.
The noises from the pump rooms have been significantly decreased, they are now quieter than they ever have been. Whilst the noises are
still there, no post construction acoustic product will completely nullify the sounds / noises – only the correct treatment during
construction may have achieved that – but I sincerely believe this product has achieved the best possible outcome.
Within the pump rooms themselves you can definitely notice the difference in noise levels, but most importantly it has absorbed a lot of
the sound internally which means the transfer of sound from the pump rooms into the adjacent apartments and corridors has reduced significantly
too – which is the most important thing. I believe this outcome is the best possible outcome given the circumstances.
The install carried out was quick, thorough and professional also. It was never intended to be a perfect, clean install but still, the
product (and the install) have achieved a very clean and neat finish.
As with the product itself, I am very satisfied with the install and how the level of installation, along with the quality of the product,
have worked well together to achieve a great outcome.
