A Checklist for Acoustics in Class

Finding the reasons why children are having issues with learning at a basic level can be a tough experience for parents and guardians. It is imperative for parents and guardians to pay adequate attention to the environment which accommodates the classroom where their children are being taught. Research has shown that a significant percentage of the number of the children might have their learning experience hampered by extreme noise and reverberation. As a parent, you need to take necessary steps to know if the classroom in which your child is being taught needs acoustical remediation. If the issue of reverberation and extreme noise are not adequately put in check, it could cause educational failure and delay in children.

Problem of Reverberation

Reverberation remains one of the problems that could make the learning process a terrible experience for kids. Once a room is reverberant, it lacks the capacity to absorb sound, and this will not allow the children to hear and grasp the content of the tutorials given by their teacher. When there is a case of extreme reverberation, it will be hard for the students to understand what they are taught. The good news about reverberation is that it can be dealt with. There are several hints that you should look out for when you want to know if reverberation is the main issue. These tips may include;

• Painted tiles in the classroom

• The ceilings of the classroom are above ten feet

• The classroom is comprised of a solid ceiling that is bereft of acoustical ceiling tiles

Check for Background Noise

Causes of background noise are as follows; adjacent land uses, conducts in adjoining rooms and HVAC equipment. Getting to the root causes of background noise will need the expertise of a professional acoustical consultant. You can perform the following series of tests in a vacant classroom:

1.1. Switching off HVAC

The first step to having an understanding of the classroom environment is by requesting the teacher or instructor to turn off heating, ventilating, and air conditioning equipment for crucial lessons. It should be noted that equipment that makes more noise than a gaudy whisper might change the way a consonant sounds to children.

1.2. Check for Outdoor Noise in the form Of Automobile Traffic

Constant occurrence of noise will hamper the speech clarity in the teaching space as well as disrupt the purpose of learning.

1.3. Check for Sounds in Adjoining Spaces

This method works better when you have all the HVAC gear turned off. Once you are hearing the sounds from adjacent spaces or rooms or movements of activities in other rooms situated within the same environment, there is a likelihood that the classroom is not entirely insulated against diffusion of noise. It has been proven that when there is abnormal noise level at the background, the teachers or instructors will be forced to increase the tempo of their speeches. Moreover, here is another technique which entails the utilisation of all the HVAC and lighting apparatus in full operation. Check for the place that has the highest volume of noise in the classroom, shut your eyes as this will not allow you to read the lips of the teacher and pay attention to how the teacher mumbles few words that share the same sounds from a close distance. If you realise that you have issues getting the phrase correctly, it is most likely that the classroom requires acoustic resurgence.

You can exploit a device called a sound-level meter to check background noise. Ensure the sound meter is of durable quality that can provide analyses lower than thirty-five decibels. Make sure you carry out tests in classrooms to discover the sources of noises. Once a classroom is with a vacant background sound intensity that is above 35 decibels, such a classroom doesn’t have the capacity to offer the speech lucidness young kids require for language reading and acquisition.


Sheetrock – What Is It?

Sheetrock is a type of drywall and is manufactured and a trademarked product by US Gypsum Company, one of the leading suppliers of drywall in the world. It is also referred to as gypsum wallboard. Sheetrock is a blend of natural gypsum, water, and sand that is pressed between two heavy sheets of paper. It is a construction material that is used worldwide to build architectural elements like ceilings and walls. It was invented in 1916 but it took another thirty to forty years before it caught on with builders, who had traditionally constructed walls from plaster.

Benefits of sheetwork vs plaster

• It is faster to install sheetrock than it is to install plaster
• Sheetrock can be painted or primed immediately after it has been installed so the building of the home or office can be continued without any delay. With plaster it needs days or even weeks to completely dry
• Plaster weighs more than sheetrock so there is less wear and tear on the building’s foundation and structural systems
• There is a higher level of fire-resistance with sheetrock than there is with platter. This can give the ones in the building more time to exit the building safely in an emergency like a fire.

Size of sheetrock

The standard sheet of sheetrock measures four feet by eight feet but for buildings with specialty requirements or have high ceilings the builder can get larger sections. Generally, the interior walls of a building are constructed from drywall that is one-half inch thick. If the building’s walls are going to be subjected to more wear and tear, the builder can find thicker sheets of five-eights thick. If there is a curved wall, a builder can use sheetrock that is one-fourth inch thick. The sheets of sheetrock can be shaped because they are moderately flexible.

Types of sheetrock

There are many different types of sheetrock that can be used for different applications.

• Traditional-it is naturally fire-resistant but the builder can choose Type-X, which is fire-rated sheetrock. This sheetrock is enhanced with vermiculite and perlite to increase its resistance to flames and heat. Builders use Type-X drywall in commercial buildings, which has fire-rated ratings from twenty to one hundred eighty minutes.

• Greenboard-this gets its name from its green paper coating, which is a material that is moisture-proof and is used in bathrooms and kitchens.
• Blueboard-this is the type that a builder would choose if the owners want the walls to have the look of plaster.
• Soundboard-this type of sheetrock is constructed to block the transmission of sound between different rooms. It can be installed in multiple layers to make sure that the levels of noise can be maintained.

Replace the Core Wiring With a Silicon Wire

Are you planning a rewiring to your home or office? Are your searching information about the wiring material and best quality wiring variety? Then here we are giving you little insights on silicon and its uses over standard wiring which could give you an idea for your rewiring or wiring works. A silicon which is also known as silicon insulated wire is the newest thing in the market that is almost replacing the core wiring material.

The silicon insulated wiring has got many benefits such as flexibility, more protection, and higher life time and so on due to which majority of the electricians today suggest silicon over standard wires. Besides the silicon are more popular in these days because the material used in manufacturing silicon wires is of such type which can resist high temperatures. This ability of the silicon wires is the only USP that has made silicon wires more famous within no time.

The only USP of silicon wires is also the only aspect that many industries look for as those industries bound to use high temperature in their processes on a daily basis. For example, aerospace industry is one among such industries which use high-temperature equipment for their operational activities. These silicon insulated wires are of great use for such companies/industrial units. Apart from aerospace industry there are industries such as, pharmaceutical, automation and ribbon applications which use high-temperature equipment in their manufacturing operations.

Apart from high-temperature resistance these wires are also resistant to aging, chemical substances and can also sustain extreme conditions. Keeping in view all these properties of silicon wiring system many companies and homes are replacing their core wiring with silicon wiring. Keeping in view the multitudinous requirements of resident and industrial customers the silicon wire manufacturing units are manufacturing the wires in different grades and formulas to suit the wires to the needs of multiple customer segments.

The high temperature and high voltage resistance feature made silicon wires more popular in the market and the availability of these wires in different grades that suits to the temperature levels made them much familiar among the customers. There are silicon rubber insulated wires too in the market which are resistant to both superior heat and cold temperatures. This variant is an extension to the normal ones through which you can use silicon temperatures at any locations with high to low temperatures. The insulation property of these give them more resistance and life.

The professional will also give you some tips to address the common issues with your home. You can then take necessary steps to solve the issues.

Seal The Walls

The seals in the walls allow the air in, which causes fluctuations in the temperature inside your house. You can make a plan and use a tube of caulk to address the problem areas. Aside from this, you should seal the areas where you can find electric boxes on the drywall. Make sure all the tiny holes on the backside of the boxes are sealed.

Seal The Can Lights

Air leaks can occur in the ceiling as well, especially the area on the ceiling where the recessed lights are located. Some can lights are vented so that they don’t get overheated due to the light bulb. What you need to do is remove the can and then seal the perimeter of the can with quality caulk. In the same way, the internal area of the can should be sealed with aluminum tapeto or caulk.

Fill The Insulation Gaps

To find insulation gaps, you should check the outside faucets and air vents for big gaps. These gaps will allow the air to escape from the room in winter. You can use expanding foam to seal these holes.

Your Heating System

Before the arrival of winter, you can get your furnace tuned up. According to experts, the energy costs of an average house are affected by the heating. If your boiler system or furnace is inefficient, your heating bills may rise. Make sure you buy a quality filter.

You can replace the filter to make the boiler more efficient. While this may seem an unnecessary expenditure, it will pay back down the road.

Check Your Windows

Your windows should be suitable for the climate of your home. For instance, if you live in an area where it’s very cold in winter, you may want to invest in windows that feature double-paned insulated glass.

Buy a Smart Thermostat

You can consider installing a smart thermostat. Some advanced models can be operated with a smartphone as well. Programmable thermostats are available in different designs and price levels. These devices allow you to enhance the energy efficiency of your home.

Home Improvement Loans

Home Improvement Loans – Transforming Brick and Mortar

There is no courage in living an existence where you are constantly dissatisfied. Accepting your current resident as package you can’t exchange is a myth. On the contrary it is true that not everyone has available money to finance home improvement. Home improvement loans enable every resident to own and construct the house that is home in the real sense of the term.

While looking for Home improvement loans the first thing you concentrate on is interest rates. Borrowers must look for low fixed interest rates. The advertised rates may or may not be low rates for your profile. You will learn that interest rates are a personalized concept. Interest rates for home improvement loans are primarily dependent on whether you offer a security for the loan or not.

Consequently, home improvement loans are either secured or unsecured. Secured entail collateral. On the other hand unsecured home improvement loans get approved without security. Both loan types come with their own set of advantages and disadvantages. Secured loans for home improvement is ideal for raising large amounts (£25,000-£75,000 or above) at low interest rates and flexible terms. Home improvement loans that are secured come with downside of losing your property in case of failure in repayment.

The Home Improvement Nightmare-Who’s To Blame and How To Avoid It

Unless you live in a remote part of the country with no television, newspaper or other people to talk to, there is a good chance you have heard or read about a home improvement scam or project gone wrong. It seems to be a fact in this country that when you go about doing a home improvement project you will usually encounter countless problems, delays and shoddy work.

The home improvement experience leaves most people stressed and vowing never to do another project again! So it is not surprising to hear that home improvement complaints rank at the top of consumer complaints nationwide year after year. Where does the blame fall for this epidemic of home improvement problems?

I am proud to say I was a home improvement contractor for almost 30 years and I was fortunate enough to win some of the industry’s highest awards. However, it has never ceased to amaze me the poor home improvement decisions that I have seen so many homeowners make. One of the more notable mistakes I would see done over and over again was when a homeowner would blindly hire someone to do a project because the person was a friend or a friend of a friend. To me this reasoning makes no sense.

Friendship and craftsmanship are not related, but for some reason a lot of people believe other wise. Another great example of homeowner apathy is hiring someone to do a project without ever putting anything in writing. Who in their right mind would ever agree to such a disastrous situation? Another very similar blunder would be for a homeowner to blindly accept an estimate on the back of a business card. Usually the only information that has room on the back of a business card is the PRICE.

A major mistake made by many people doing a home improvement project is letting price dictate the decision on who to hire. More problems occur because homeowners pick the lowest price they can find. Why? It is very simple. You can only produce a high quality project at a certain cost. High quality materials, expert labor, appropriate insurances and a reasonable profit to stay in business, cost a certain amount of money.

If someone can do that same project under that amount, what do you think is going to happen when the job is being done? That’s right, the person or company is going to do anything they can to try and make a profit. All of the possibilities that could result from the person you hired, as the low bidder, trying to make a profit, are simply all BAD for the homeowner. In home improvements you get exactly what you pay for.

Let’s not forget to put some of the blame on people looking to work on your home. Over the years I have seen some of my competitors commit heinous business practices. (Surprise!!) I have seen contractors switch materials to lesser quality without customer approval, use unqualified labor, overcharge homeowners for “unforeseen problems”, try to up sell the customer once the project starts, etc.,etc.,etc…….it makes you wonder if you can trust anyone?

So where does the blame fall for all the home improvement complaints year after year? I guess it would be easy to blame the homeowner for not educating themselves on what to do when attempting a project. However the next question would be where does a homeowner get “educated”? Maybe a better question would be when does a homeowner find the time to get “educated”? Education is a great tool if you have the time to do the research. Most people don’t have the time or want to take the time to do hours and hours of research on how to go about getting a home improvement done correctly.

Oops I almost forgot Uncle Sam. A lot of people, including myself, think the government makes it too easy for someone, who has no ethics or skills, to do home improvement work. Why are there still some states that do not have licensing for people doing home improvements? And in the states that do have licensing, why are some of these states issuing licenses without the applicant needing to demonstrate any type of competence in home improvement work? This is like giving out a driver’s license without taking a road test. Doesn’t make much sense to me.

One last situation to blame, one that I would never forgive myself for not mentioning. Home improvement television shows have become the latest fad in television. You can hardly change television channels without a home improvement program popping up. The influx of home improvement shows on television has been phenomenal. However, most of these shows tend to unrealistically glorify the home improvement project as being easy to do with nothing ever going wrong. The last time I looked, nothing ever goes perfect, including home improvement projects. Little, if any information is mentioned on these shows, about how not to be “taken to the cleaners” when doing a project.

One would have to conclude that there is plenty of blame to go around when it comes to the problems homeowners face when attempting
