4.       What is the difference between sound absorption and sound attenuation?

Sound absorption relates to the control of sound reflections within a room while sound attenuation is associated with the control of sound transmission between adjacent rooms via a continuous suspended ceiling.

Simplifying The Job But you can get around the worst part of putting in a soundproof ceiling if you can manage to do your work not directly beneath it,

but from the floor of the room just above it. By soundproofing this floor you will stop any noise before it ever gets to your ceiling, and this technique is ideal for use in multi-story buildings like offices and apartments, in which the noise made by the people on one story can disturb those working or living directly below them.

If you’ve ever lived in an apartment with someone living just above you, you probably know how much a soundproof ceiling would have increased your comfort in that situation. If you are living in an apartment now, you might approach your apartment meager about having access to the upstairs unit so that you can soundproof its floor and avoid the hassle of putting a soundproof ceiling in your own unit. Acoustical Ceiling Tiles And Resilient Bars But if soundproofing an upstairs floor is not an option you’ll be faced with the job of installing a soundproof ceiling. In doing so, however, you’ll not only be faced with the physically challenging job of putting up the soundproofing materials; you’ll be reducing the height of the room.

You can simplify your job by deciding to install acoustical ceiling tiles, which will do a moderately good job of preventing noise from bleeding down from above, but for a really soundproof ceiling, you really need to add a new layer to your existing one. You would do this by putting in resilient bars, which are designed to keep your original ceiling separated from the new one. You would first install the resilient bars, and then place your soundproofing materials like rock or mineral wool, and American mass loaded vinyl into them, before adding the drywall which will be the surface of your new ceiling. While this will be a lengthy and difficult job, it really is the best way you have of creating a soundproof ceiling which can give you the peace and quiet you deserve. Before deciding on the best method of installing a Soundproof ceiling for your home or office, be realistic about your level of expertise, and don’t attempt an installation which is beyond your capabilities. While you’ll have to pay more to have your soundproof ceiling professionally installed, doing so is the best guarantee you have that the job will be done quickly and effectively!

How to Install Drop Ceilings

A few grids, some ceiling panels, a few wires and some elbow grease is all it takes to install drop ceilings. If you still have questions, then read on…

How to Install Drop Ceilings I feel every person has dormant creativity residing in him/her and sometimes it only takes a simple incident to bring out that spark!

I begin this article with the above line because I feel that home improvements and decorations that are done by the people who inhabit the house reveal their identity. So go ahead and learn the process of installing drop ceilings.

A drop ceiling What is it? This ceiling is composed of a metal grid and ceiling panels that are placed in that grid. They are often composed of translucent materials that cause an overall glow from the ceiling. The sizes of the drop ceiling panels vary.

The most common size that is available is 2 feet by 4 feet. Light fixtures can also be covered using drop ceilings. Today there are drop-ceiling tiles available too. These tiles come in many textures and colors, ensuring that you have a ceiling treatment that matches your d cor. Benefits of Drop Ceilings Drop ceilings are a good choice of ceiling treatment for many reasons; some of them have been listed below. * Efficient and Cost-Effective Drop ceilings can be used in a basement or laundry room because they are more practical. The reason for this is that drop ceilings do not consist of much construction and the materials that are used are economical. * Provide Sound Control These ceilings score above concrete ceilings because of the property of being able to soak up residual noise.

Drop ceilings have this feature because they are made up of fibers, which are terrific acoustical absorbers. * Provide Cover-up For Faults Despite the fact that drop ceilings are used to conceal unsightly pipes and electrical wiring, they do allow easy access to the equipment too. To reach the equipment all you need to do is lift the panel provided. * Provide Leveling A drop ceiling can be used to correct any leveling problems. This is possible as the metal grids can easily be adjusted to different heights as they are installed. How to Install Drop Ceilings

Here are the steps that will help you install a drop ceiling: * First of all it is important to decide on the style of the drop ceiling that you would like to use. Once you have done that decide on how many drop ceiling panels you will require. * Now center the panels within the room ensuring that the perimeter panels are of equal size as possible. * After the above process, it is important that you figure out how to install the drop ceiling. Remember that the minimum ceiling height that is required is 7 feet 6 inches. Also note that the drop ceiling needs to be installed at least 5 inches below any lights and three inches below any plumbing. * Once the above process is over, install your drop ceiling perpendicular to the joints; to do this you can follow the manufactures instructions. The common process that is followed for installation usually requires eyehooks to the joists and a wire that is used to hang if from the ceiling. While installing the ceiling, ensure that you are using the recommended type of hardware and wire. * Use tin snips to cut long pieces of wire and then make sure that all intersections in the grid are carefully secured. You can use a level to ensure that the drop ceiling is not being installed at an angle. * Place the panels into place after the installation of the grid. To fit the space, cut the perimeter panels into place (note that the actual panels are a little larger then the hole in the grid). Tips * All you need to do to ensure that the panels are equal in size and the number of panels you have calculated are right, draw a diagram of your ceiling on graph paper. While doing do remember to use a box to equal one square foot. When that is complete, draw the panel system onto your diagram. * You would be required to keep a saw handy to cut other panels apart from soft, absorbent and drywall panels. * If you are unable to procure the proper equipment or cannot cut it yourself, you could take the panels to the nearest home improvement store. Most of them will cut it for free. I would like to end by informing you that there are times when installing a drop ceiling becomes difficult because of awkward angels and the use of ladders. It is advisable to call a professional if you are uncomfortable with the task.
