Elevator Noise Control


Ben,


Thankfully, there are a few things you can do if you are considering working in a room that is located in the proximity an elevator shaft. First you must determine the source of the actual the noise. Yes, it’s coming from the elevator - but why?


Is the nhoise coming from the cable system or motor attached to the elevator itself or are you next to the operator room? Answering this question will help you to determine if you are trying to treat operating noise (or flanking noise) or against the sound made by the impact of the elevator reaching the top floor.


If the noise is coming from the elevator shaft itself, from the movement of the cables and motor, you should be able to solve your problem by installing a layer of mass loaded vinyl over the offending wall.


The project may become a bit more complex if you find that the noise is caused by the impact of the elevator itself or the switch used to control the elevator. In this case you might need a composite material like our acousti curtain. Call or email me I'll come take a look.


Pretty soon you’ll be able to enjoy a good night’s sleep without wondering which neighbor just got home!







Ben,



Elevators are a common application for Noise Control. We generally identify the source of noise (the drive, lift, or, box itself) then it is a matter of treating the source or sources. Metal panels or acousti-curtain are usually the best option for the shaft and operators and fabric or metal panels are best for the box.

Noise Control for Bulk Powder Operations




David,


The Acousti Curtains come standard in grey but we can do white or black for the same cost. White is very common in food processing noise control applications. We can do almost any fabric if its durable enough. Check out our Guilford 701 selection at

http://www.noisecontrolproducts.com/sound_proofing_fabrics.htm

We also make a white all vinyl noise control enclosure that is virtually maintenance free.

Noise Cntrol Enclosures



David,


We like the combination of flexible and metal panels for Noise Control Enclosures too. For large areas that don't get alot of wear we go with ArtWrap baffles or Acousti Curtains. Noise control in the plastic grinding area was pretty straight foward because the primary sources were easy to enclose. The production and molding areas will be treated as general areas rather tha source enclosures.

Courtyard Sound Fence


Ben,

The ArtVinyl Sound Fence is perfect and virtually maintenance free. Both the tan and the biege are great neutral colors for that style of multifamily application.

Noise Control for Overhead Doors


Ricky,

We have a cost effective solution for noisy overhead doorsand allows total access. This photo gives you the idea. It gets dampened metal side and top piece as well. A door like yours would be a little less than $3,500.00 installed.

Gas Compressor Noise Control Enclosure Silencers





Pete,

On the S-65 SF Noise Control Enclosure System the air intake silencers can project inside or outside depending on space allowed and air flow requirements. The intake silencer banks usually have interior or exterior louver and birdscreen. They can also include fans for forced air and filters or dampers. Read the section we were looking at on www.ies2000atlanta.com

Sound Fence Bottom Mount Post


James,


The bottom mount post for the ArtVinyl Sound Fence has a base plate that anchors to the footings or slab.

Gas Compressor Noise Barrier


James,

Yes there is a great alternative. The S-65 is the best choice for an enclosure for a large gas compressor, however the ArtVinyl sound fence is a great barrier wall . If you go 15' or less in height the existing slab will work for a footing.

Acoustical Foam on ceiling


Linda


The guy from our shop that did it last time is Melvin. He added the 1 X 4's because the ceiling was dry fogged and there is alot of vibration in there. Let me know when you are ready.

Mechanical Room Noise Control


Linda,

What you see in the adjacent room is acoustical foam applied in a checker board pattern to the ceiling and walls. The bigger squares save time and money compared to the performance area but it is the same concept in both areas.

Effective Roof Top Sound Fence


Doug

The sound fence that is working so well for the landlord is our ArtVinyl. It is light on weight but heavy duty on knocking down the sound. It is perfect for roof tops and bridges. We have side or bottom mount post. There is a good explaination of the 3 types that we talked about at www.acousticalsolutionartusa.com

Gas Compressor Enclosure


Pete

The best noise control enclosure system for the gas compressor to meet the specs you sent is the S-65 SF. Please see more details at http://www.noisecontrolproducts.com/

Noise control ceiling mounted clouds


Sgt Thomas,

That band and their new room rules. I have emailed the ssgt's phone number so you can schedule a time to get in and take a listen. The panels and clouds in that application were a combination of reflective and absorptive because of the room acoustics. The curved panels you see there are diffusers. Your job will require absorptive only. Our focus is reducing the echo in the the room. We can make you some curved panels if you like that look.

Gas Compressor Noise Control Enclosure


Habib

The noise control enclosure system your looking at is our S-65 MW in the 4 inch version. That is around a gas compressor. The S-65 SF (for self framing) it also comes in Alum A Frame when it is less than 10' wide. The enclosure has blow out panels incorporated into several areas including the shut off valve access doors. It has hundreds of application for the power generation market. Send us a drawing of your compressor and we can price it for you. We also have a pricing program available to OEM's that have purchased
more than 3 enclosures.

You are very perceptive and that would have been great if the original wall construction were different. In which case the absorber panels are usually not continuous. Those panels are an S-65 BA composite (meaning they are both a barrier and an absorber) perforated metal panel attached to the wall and ceiling. They requie a base and header track or channel. The acoustical doors and windows are ArtSeal 55 (they metered out at 58) They look great and are easy to clean and or change out.

Thank You. We love the way it looks too, and yes it is extremely effective because of those holes in the back. Really there is nothing wrong with using trees as a screen or barrier but in this case the original trees had become ineffective and there was not time or room to use new ones for an acceptable acoustical result. The Art Vinyl sound fence is far superior to the trees for 3 reasons. One because it forms a solid sound barrier with no gaps for the noise to get through, two because as an assembly it is a better blocker , and there is more absorption in the right place, and three because it was much more cost effective.


The reason we use a hybrid acoustical enclosure for that application is to provide the needed sound reduction and access. The S-45 alum a frame enclosure is like the skeleton and provides a light weight but sturdy frame. It has a few S-45-MW panels permanantly fastened into locations that don't require access. Then it has our 2" thick BA ArtSeal absorptive swing doors where constant access is required. Then finallyas well it has flexible BA style acousti curtain or sound curtain / blankets on a sliding track where intermittent access is required.
Eedie,

That's GREAT and I really appreciate the comment about the clean up. Our customers often have that same epiphany when we finish. The fact that you can hear things you could not hear before like the robots transition and release as well as the squeaky bearing means the noise control methods are working really well. It's nice not to be yelling at one another. Even though your area was not part of phase one you get the cumulative effect of the absorption. You are benefiting from the absorption of the baffles and banners down the line.The Reverb Time in your area is down from 8 to 6 seconds and the TWA for Steve was down from 88 to 83 on a GE BF run day.That is a really impressive start and meets your TWA target, however I highly recommend going ahead with phase 2 and 3 as soon as possible. You already have the material on hand and the majority of it can be done without any abnormal down time. The TWA results will drop and speech intelligibility will improve.We can be there within a couple of days notice.
