We get alot of requests that sound like this…

We live in a condo/home where we get alot of excess and disturbing noise from Neighbors/Dogs/On-going Construction … How can we prevent this? Most often this is followed up with a – How can we do this temporarily or without spending much money.

Well – you all have a bit of an uphill battle. Acoustic products can often be costly for the residential consumer as well as aesthetically what they didn’t have in mind. For industrial and commercial users, they happen to be very cost effective and fit in their environments. However – there are a few products and a few things that can be done for these types of problems. First let’s explain how noise works, then give you products and practical sense that will make a difference in your home.

Sound.. how does it work?
Sound is energy/heat. It travels in sound waves. Each time a particular sound wave hits an object it reflects. The material it hits can either magnify that deflection or soften it. When it softens it, it is essentially losing heat / energy. Any soft, open celled ( porous ) material absorbs sound while the heavier products like sound barriers deaden sound. By deadening the sound hits that heavy product and looses much of it’s energy. Another way sound travels is along materials. The sound waves will actually travel through various woods, metals through vibration. So now that we know how sound works, lets look at products and household items that can absorb sound….

Noise From ….
Balconies!First – lots of complaints coming from balconies and/or sliding glass doors. The right way would be to hang quilted fiberglass blankets essentially enclosing your balcony. Problem is- they are industrial looking and may very well look like a bandaid. My first thought is that if enough complaints are received, the construction company themselves, should be enclosing their construction zone with these acoustic blankets. This is one of the main uses of these blankets. But, that may be alot of effort and red tape. So if your ears are screaming and aesthetics are no longer a worry, we manufacturer shorter life acoustic blankets that would very much quiet things down and save money over the heavy use blankets..

Another product I’ve thought about was acoustic fabrics. Again, commercial looking and usually affixed to walls, it is flexible enough to create a curtain effect. By hanging a pole and grommeting the top of the fabric panel you could create a curtain. You can slide panels back and forth or tie them back. The rods and tie backs would have to be fastened into studs or concrete or require anchor large anchors as the weight of these panels will be substantially heavier then curtains. Since alot of noise does travel through windows and doors, consider extending the curtain panels a little more beyond the windows than you may normally. If the curtain abrubtly ends only 1/2″ past the window, you can be assured that noise is coming easily past that. Extending the curtains 5 or 6 inches can create a handsome effect and absorb more noise.

Shared Walls/Floors/Ceilings!
Townhouses, condos, mother/daughter, two or more family homes… we all know your pains! You move in, quite likely renting or have requirements or restrictions on what can be done… and if you hear your neighbor click across the floor, or the kids jumping, or that music coming through the wall one more time your going to scream! Well we can help. The first solution – IS the most effective, however the most costly.

Shared walls meets mass loaded vinyl barrier.
Most of the time it’s only a specific span of wall that creates this problem. We know sheetrocking is not fun, however by purchasing sheets of mass loaded vinyl barrier, some glue and refinishing a wall with sheetrock will do wonders for peace. The vinyl barrier can simply cut to size and glued to the existing wall. Another layer of sheetrock would be placed over that, preferably with adhesive and screws. This adhesive will bond the sheet rock better to the vinyl barrier and anytime you get a more solid bond between materials, sound looses some energy. Then refinish your wall and you’ve merely lost 3/4 to 1″ of space but gained piece and quiet. If you own the home/condo/townhouse, you can consider simply leaving a few inch space and actually building a second wall, in the same fashion with vinyl barrier, right in front of the problem wall. The space actually acts as a noise absorbent as well. Visit our vinyl sound barrier page for more diagrams and information.

Foot Fall
You already know the answer.. with hardwood floors being the flooring of choice, foot fall ( noise from walking ) is even more common. The best method is to prepare for this before floors are installed and it uses the same method as above. Vinyl Sound Barrier laid above the studs, and beneath the sub floor will greatly reduce this. IF this is not an option, we are sorry – you’ll need to look to carpeting and/or area rugs to help absorb that noise.

If your problem is from your neighbor above you, then you have some options if you have drop ceilings. Ceiling tile barriers and replacing your ceiling tiles with acoustic ceiling tiles will help reduce that noise. And if you have an incredible knack for design or have the budget for a designer, you can look into fabric treatments. There are designers that fill rooms and drape fabrics from ceilings creating warm effects. It’s an option, however not for all of us.

So let’s now look at the resources around you that should be implemented along with any other noise control method we suggest… let’s look for natural and household solutions…

These will help for all scenarios… Plants! If you happen to be on ground floor, then planting larger bushes and such materials along the perimeter of your yards will certainly help absorb noise. On balconies, some big leafy potted plants will aid in your noise battle. Another surprising thing is area rugs and tapestries on the wall or creatively suspended from the ceilings. Remember, if noise hits surfaces and bounces around, the more soft surfaces it hits means the noise energy dissipates faster! Not only are you treating your noise problem, but you’ll improve privacy and overall acoustics in the room for conversations, music and so on.

Along these lines, a layered approach may tackle or add to the noise control solutions above. For example, by using one of the methods above on the exterior, you should also go to any home decorating store and look for the heaviest, thickest curtains they have available. Placing these on the inside of the doors will further muffle the sound.

Carpeting, area rugs, tapestries in home…
All these surfaces will help absorb noise.. they will help muffle noises coming in, going out and around the room. If you have children or entertain alot or have TV’s or music on, you can create rooms and effects that help control the noise within your home. The way to consider it is – do you want to contain/isolate the noise or do you want to control or absorb it. Just think if you’ve ever walked into an empty home for sale, the echos you hear from your steps and voice. A couch, curtains and an area rug and voila – it doesn’t echo near as bad. Some canvas art ( glassed art will only create additional reflections ) and some tapestries or wall hangings practically reach out and suffocate the noise bouncing around walls.

In-door Plants - even if you need to have fake ones, if they fit your decor, they can create natural barriers that sit and absorb noise.
Anything layered and anything soft will help absorb noise and help solve most of your noise issues all while making your home coizer and more pleasant.

Have fun and we hope this helps all the ears that need help solving problems from noisy neighbors, dogs, construction companies and yourselves (or your children)!.

Home Engraving & Metal Working Shop Noise June 9, 2008

Hi, I own a small rotary engraving shop in my home. The noise level when cutting plastics, steel, and alumium is very high.The shop is 1000 sq feet, located in the basement and includes an office area. It can be very difficult to talk with customers on the phone when jobs are running.

Kathleen,
Quite an obvious and common problem as noise levels can reach very high levels with rotary engraving. To best help I would need to know more specifics about the layout of space, use of tools and aesthetics required but here are some suggestions for you.

Typically you would try to isolate the noise source, but I imagine this is much of your 1000 sq ft space. You mention composites and barrier composites would certainly help and our easy to retrofit into existing space. These are traditionally used to enclose machinary and noise source as they can be easily cut to any shape and fit into spaces of many sizes. However in your case you can use this to line the inside of your office isolating you from the noise. There are several varities of barrier composites that have mass loaded vinyl mounted to a foam absorbent.

If your office happens to be unfinished then idealy you can use composites or even just mass loaded vinyl barrier beneath a layer of sheet rock or sandwhiched between sheetrock which would give you additional noise control and allow you to finish your office however you like.

Since quite a bit of noise will escape through doors, you may want to consider that as well. There are products that are quilted absorbents made from fiberglass quilted blankets that retrofit onto doors since much of the noise entering a room will enter though the gaps in the door. This acoustic blanket door panel actually overlaps the door to cover and absorb noise coming through the gaps in the door.

I am thinking that if your “noisy” workplace where all the engraving is done is isolated on one side of the space, that industrial acoustic blankets would best serve you. They come in a variety of configurations including the heavier use blankets that have 1lb mass loaded vinyl sandwiched between different 1″, 2″ and 3″ options of quilted fiberglass absorbent. We use these in industrial metal stamping plants and places like water treatment facilities etc. They could be hung from the ceiling by fasteners or hung by track systems. This option could allow you to roll blanket panels out of the way and would best isolate the engraving noise. The acoustic blankets can have windows cut in if needed and can dramatically cut off the noise coming from the heavy noise workplace.

Another product worth mentioning that would be a simple install is to retrofit Acoustic wall panels onto your office walls. These will quiet your office and give you good acoustics in the office and may suffice with a little extra help from a good noise cancelling phone!

The last thing I had thought of is if your basement has drop ceiling alot of noise will travel through that space. We have ceiling tile barriers that lay atop the ceiling tiles. If you were to install these above your office space and a few extra tiles beyond to isolate your office from the noise as well.

If you have details on the room space, please email info@allnoisecontrol.com describing your space and problem and we’ll be happy to answer.

Reaching Acoustic Harmony & Dealing with Noise Control within Churches & Houses of Worship August 20, 2007

Noise Absorption and Acoustic Problems with Noise within Houses of Worship

Houses of Worship acoustics require special attention and knowledge to the nuances of voluminous spaces, hard surfaces, especially in the new architectural designs of today’s buildings. This excessive space is wonderfully impressive but allows for significant reverberation, which we are familiar with as echoes. Reverberation can reduce speech legibility and can make otherwise good church sound systems sound awkward. Imagine your ear being bombarded with an array of sounds at different decibels repeatedly served in waves. These sound waves maintain a surprising amount of energy and continue on absorbing and interfering with other sound waves. This is overwhelming for our ears and the echoes and spoken word dilutes more and more with each wave. This reverberation problem and acoustics and noise control in general are quite complex in nature and more often than not require expert knowledge to solve such problems.
There is a difference between typical noise control such as industrial noise, construction noise, commercial / retail noise and ‘church acoustics’. Simply absorbing excess sound, as done in many commercial and industrial applications, is not the best approach for church acoustics. Noise control solutions ideally need to be configured by professional noise control specialists to balance noise absorption, noise reflection, noise barrier products and all while delivering them in a finished aesthetically pleasing result. The vast reflective wall areas within houses of worship benefit from being broken up with interesting acoustic materials and/or colors and often the vaulted ceilings require elaborate baffle systems. Floors, as well as walls and ceilings, during construction of new buildings will benefit from an entire line of specialized acoustic materials such as mass loaded vinyl barrier material or ceiling tiles & barriers used beneath the visible surface; within the construction material (i.e. studs, sub flooring etc)
To help better understand you need to move beyond the materials to the sound itself. When speaking of sounds, most people think of the vibrations in any type of medium, which can cause the sensation of hearing. Any unwanted sound is perceived as a noise. The term is definitely subjective, since what is music for one person can very well be noise for another. When such unwanted sounds are excessive, their effects can be destructive, which is known by the name of noise pollution. Noise pollution or noise levels are rated by what we know as decibels. Decibel (Db) is the volume of noise emitted from the originating source. You’ll see “db” next to all types of products such as printers, power tools, appliances and others to great to list. This is the rated noise level of the originator of the noise/sound. Little known is the impact that noise does indeed have on our communities and lives. Adverse noise effects fall into three categories, physiological, psychological and communicational. Unfortunately, there aren’t any known and adopted remedies for the last two categories. Noise pollution is a complex problem and surveys show a disturbing fact, that noise levels are continually rising in cities. This gives us many positive reasons to focus on improving noise quality in other aspects of our life. Such as home, worship buildings and work.
As far as the sounds inside buildings go, we can speak about two main ways of transmission. It may be quite surprising how sound does travel through buildings and environments.
Firstly, the sound emanated from either human activity or mechanical noise inside the building travels airborne against and through walls, ceiling or floor. This is obvious and actually slightly more difficult to control. However acoustic wall, ceiling and floor treatments will help absorb the excess sound energy and help filter out and control the noise. Hanging baffles from ceilings, often seen in the likes of gymnasiums, are an excellent way to absorb the array of excess sound waves causing the echo and reverberation problems.
Secondly, interior sound can be transmitted not through air, but through the building itself. The former is easier to abate than the latter through wall or ceiling assemblies which meet certain established performance standards.
For example most of us are familiar with ceiling grids, the ceiling tiles in grids you see in retail, doctor’s offices, class room areas of schools and churches. Well those grids are suspended simply by metal wires. Sounds hit the ceiling and grids and their vibrations travel up through the ceiling to the floor above creating noise. Through walls sound actually travels through metal objects such as nails, screws and such. Sound travels effortlessly through all types of materials, electrical wiring, support framing and especially gaps, such as electrical sockets, doors, windows etc. Now many sounds from human activity include loud voice or amplified systems to reach their intended recipients clearer; however this often increases reverberation and echo amplifying the problem. Mechanical noise refers to the sounds produced by elevators, generators, air conditioning systems and so on. The sheer sizes of some churches require incredibly large HVAC (Heating and Air Conditioning Units) to keep rooms comfortable and temperature controlled. These mounted on roofs often require special know how and materials to reduce the noise and just as important, vibration from these types of mechanical equipments.
To complicate some problems further churches are communal places that act as multipurpose spaces for large gatherings and events as well as venues for smaller groups and classroom activities. This variation of spaces does require attention when dealing with church acoustics; the contents, size, space and materials in those spaces require acknowledgement to all of the elements present which need to be considered. Not only in regards to the spoken word either, but in regards to the mechanical elements running the building itself. As with many sound issues some solutions do compound the problems when not used correctly. For example, an amplification system that is installed to improve volume so words can reach the audience throughout and this often compounds the problem. Now the excess sound waves are louder and reflect off of more areas causing greater distortion and echoes. Treating the noise at all its levels is one of the subtleties that are addressed when specialists consult on products needed for noise reduction and improvement of acoustics.
However, many contractors installing these systems may not realize that reverberation time ideal for music can make the spoken word difficult to understand. The structural differences of these spaces (cathedrals, class rooms, multi-purpose, private rooms) and their contents make custom acoustic solutions for your project necessary, not to mention the aesthetics in the typical House of Worship. The materials, volume of space, variety of speech and sounds are all contributing factors in making a positive experience with improved interest, attention spans and even less fatigue. When all the types of noises, building surfaces and understanding of all mitigating factors are observed and understood the end result will be harmonious.
