Abstract
The invention provides improved plumbing noise containment in new home and retrofit construction without dramatically increasing the width of the wall/floor assemblies. The invention dramatically reduces the unwanted noises transmitted from the pipes to the living areas of the home; thus greatly improving the quality of construction and lifestyle for the homeowners. To achieve noise containment in the plumbing four processes must be applied. All the pipes are isolated from the structure. All the pipes have a sound absorption material wrapped around them. The wall and floor cavities that contain pipes are treated with sound absorptive insulation. Wall and floor cavities that contain pipes are covered with a barrier material and/or acoustic wallboard. All four processes are applied before conventional wall/ceiling coverings are installed.
Description
Summary SOUNDTRAP PLUMBING NOISE REDUCTION
When conventional noise control techniques are performed only a small portion of the required noise reduction is obtainable. Using additional conventional noise reduction techniques i.e. resilient channels, in conjunction with double drywall increases the wall/floor assembly by over 25 mm. (1 "). This increase in wall thickness makes it difficult for the electricians who have installed electrical boxes and also the finish carpenters who have to accommodate door frames and trim to walls and floors /
ceiling assemblies of a non standard thickness.
This invention provides a better family living environment and reduces the amount of noise heard in a home. Particularly the noises made by liquids and solids as they pass through the hot and cold water supply pipes and the drains waste and vent pipes, without significantly increasing the width of the interior wall of floor assemblies.
THE SOUNDTRAP PLUMBING NOISE
CONTROL SYSTEM
BACKGROUND TO THE INVENTION
Plumbing noise has long been known to annoy homeowners. Homebuilders have had a problem identifying how noisy the plumbing would be after construction. Trades people install the plumbing according to the building code. Unfortunately none of the building codes apply to noise problems generated from the mechanical installation work of the pipes. These installations hard fastened the pipes to the building structure and pass pipes through hollow joist and wall cavities. These hollow cavities amplify the noises made by the fluids and solids as they pass through the pipes. The hard fastening of the pipes directly transmits noises in the pipes and does not allow for normal expansion and contraction of these pipes; thus, generating unwanted noise throughout the home.
Conventional plumbing installed to code is functional but noisy.

SOUNDTRAP PLUMBING NOISE REDUCTION
DESCRIPTION
Research and testing established that plumbing noise is annoying and the loudest and most annoying household plumbing noise is the flushing of the toilet.
According to ASHREA 'The American Society of Heating and Refrigeration Engineers' the living area's in an average North American home is considered quiet at NC30, and bedrooms NC 25. Our testing showed that noise generated by flushing the average home toilet to be 60+dB.
Therefore no known single noise reduction technique was capable of removing enough noise from the plumbing system to make the noise unobtrusive to the people living in the home.
The 'SOUNDTRAP PLUMBING NOISE REDUCTION' achieves the required noise reduction by performing the described processes prior to the installation of the wall/ceiling finishes.
~ Isolating all the pipes from the structure of the home with any kind of vibration isolation (damping material, reduces plumbing noise by up to 15dB.
~ Wrapping all the pipes with any kind of sound absorptive pipe wrap, reduces plumbing noise by up to SdB.
~ Filling the walls, floors and joist cavities with any kind of sound absorptive insulation, reduces plumbing noise by up to 3 dB.
~ Covering the floor or wall cavity or any par thereof that contain pipes with a limp sound absorptive barrier material and or acoustic sound deadening board, reduces the noise by up to an additional 10dB.

Claims (4)
- Claims A 1990 study'ON PLUMBING NOISE IN MULTI - DWELLING BUILDING' performed by MJM ACOUSTICAL CONSULTANTS inc., 655, Cote des Neiges, Burea 440, Montreal, Quebec, H3S-2A6. And published by the CMHC. Identified pipe isolation as being very important when containing noise in multi family dwelling units. The materials used to isolate water supply pipes only were:
Armstrong A.P. Armaflex Foam Pipe Insulation, nominal thickness 13 mm.
Acousto-Plumb System Acousto-Clamp pipe supports manufactured by Ancon Inc.
Double layer of cork with total thickness of 3 mm.
13 mm hair and fabric felt My invention applies to single family homes and the thin foam material used in the process provides better vibration isolation than materials tested that are twice as thick. - 2. Standard practice in the building industry is to install pipe wrap on water supply pipes only. My noise reduction process adds 12 mm. pipe insulation (wrap) to the supply water pipes as well as every drain,waste and vent pipe in the home.
- 3. The building industry often adds sound absorption to the wall / ceiling cavities that contain pipes. Unfortunately, this alone can do little to abate the noise generated by the plumbing system. My noise control process also adds sound absorption to these areas.
- 4. The 1990 study'ON PLUMBING NOISE IN MULTI - DWELLING BUILDING' performed by MJM ACOUSTICAL CONSULTANTS inc., 655, Cote des Neiges, Burea 440, Montreal, Quebec, H3S-2A6. And published by the CMHC. Identified an improved wall construction to be: (resilient channels, in conjunction with double drywall).
Wall Construction Materials as tested:
13 mm drywall 7.8 kg/m2 16 mm drywall 10.2 kg/m2 25 mm gypsum coreboard 19.5 kg/m2 38 x 89 mm wood studs at 600 mm o.c.
90 mm steel studs Resilient metal channels, type RCA by Canadian Gypsum Corporation at 600 mm o.c.
90 mm glass fibre batts. Type R-12 Home Insulation, 1.2 kg/m2.
Thermocell cellulose fibre: to install this material, 6 mm polythene sheet was attached to the studs leaving an opening at the top of each stud space. The cellulose fibre was then poured into the cavity through the opening. The opening at the top was gradually closed and the cavity filled completely. Drywall was then attached to the studs applied over the polythene sheet This recommended wall improvement increased the assembly thickness by over 25mm.
My process installs an acoustic sound deadening board inside the wall or floor assembly and covers the floor or wall cavities that contain pipes with a limp sound absorptive barrier material. This is an increase in wall thickness of only 1.6 mm.
