Noise from neighbouring properties over yours, can be quite a problem. Most common problems are Impact and Airborne noise. What is Impact noise? It is the noise caused by people walking across the floor above . This type of noise is considered to be structure borne noise and is one of the most difficult noises there is to combat. Impact noise is simply sound that travels directly through the joisting structure of the floor above, directly into the hard mounted ceiling below. Another term for this is known as "foot fall "noise. The best way to reduce these type of noise levels is to break the contact between the floor and ceiling or to create a total floating floor above. Airborne noise on the other hand can be reduce in a much simpler way. Either to create Mass to the above property or mass to the property below. The following solutions combined will help reduce both impact and airborne noise, when fitted to the ceiling area to any property.
A) Acoustic Hanger Type C
· Joists are allocated through existing ceiling · Acoustic Hangers are then fitted to existing joists around 600mm apart · New 50mm batons are fitted to the acoustic hangers · 50mm rock wool is inserted between new batons · 19mm sound plank is fitted to the batons · All the joints are then sealed with acoustic mastic · 12.5mm sound shield plaster board fitted as final layer · 3 Inches of ceiling height loss · 50-60% Improvement in Air Borne noise ** · 50-60% Improvement in Impact noise **
B ) Resilient/Sound Breaker Bars
· Old ceiling would need to be removed or 50mm batons fitted to the joists · If ceiling removed 100mm rock wool fitted between exposed joists · If ceiling left 50mm rock wool fitted between batons · 19mm sound plank fitted to resilient/sound breaker bars · All joints sealed with acoustic mastic · 12.5mm sound shield plaster boards fitted as final layer · If old ceiling removed 1 inch ceiling height loss · If batons fitted 3 inch ceiling height loss · 50-60% Improvement in Air Borne noise ** · 40-50% Improvement in Impact noise **
C) Independent Ceiling
· New joists of sufficient size to suspend a ceiling of mass 23Kg/m2 need to be installed · 100mm rock wool to be inserted into between new timber joists · Resilient/Sound breaker bars to be fitted to new joists · 19mm sound plank to be fitted to resilient/sound breaker bars · All joints to be sealed with acoustic mastic · 12.5mm sound shield plaster board to be fitted as final layer · 6-7 Inch ceiling height loss · 60-70% Improvement in Air Borne noise ** · 65-75% Improvement in Impact noise ** *Results may vary due to flanking noise and/or structural noise

FAQ
What happens to the lights in the ceiling?
· All existing lights will be relocated into the new ceiling - like for like
Will spotlights effect my insulated ceiling?
· There are many acoustic/fire rated spot lights on the market which are designed to let less noise to travel through the light fitting, but by keeping the insulated ceiling intact is always advisable as cutting new holes in the insulated ceiling leaves weak spots
How much noise am I looking to lose?
· As many properties are different and there are many factors which influence the performance of any system such as "Flanking noise" internal "Stud Walls".
· An average of 10db will give you up to 50% (Half) noise reduction.
