Efficient Sound System

Howdy ladies & gentlemen~

It's been long since my last post. I was actually busy with schedules on some of the energy management projects in Asia. I had traveled many places in Singapore, Vietnam, Myanmar and Indonesia. Most of my time were spent in the office because of the client's urgency to use the energy management system. But let me tell you one thing: Nothing beats a nice sweet home with a good warm milk listening to classical music. 

Of course you need a great sound system to enjoy the full potential of the music. I believe many home owners also have their own sound system, not only for listening to music but also to watch movie, playing blu-rays, etc. With the ever growing technologies in a fast pace and the increase of electricity bill, we certainly can afford a nice sound system that is energy efficient.

What is a Sound System?

A sound system, also known as a sound reinforcement system is the combination of microphones, signal processors, amplifiers, and loudspeakers that makes live or pre-recorded sounds louder and may also distribute those sounds to a larger or more distant audience.

In some situations, a sound reinforcement system is also used to enhance or alter the sound of the sources on the stage, typically by using electronic effects, as opposed to simply amplifying the sources unaltered.

It can also be used as a Home Theater System. The typical home-theater setup includes a TV set with cable or satellite hookup, a DVD/CD player, a receiver, and two to eight speakers.

The receiver, or AV receiver, is the hub of the typical AV system. Several types of receivers are available in the marketplace. First is a basic stereo receiver, which may include an AM/FM tuners, 2-channel audio amplifier, pairs of external speaker terminals, and connections for external CD and MP3 player connections. Second is a more full-featured home theater receiver, which combines all of the features of a stereo receiver with the capability to process surround sound, connect to the Internet, and switch and distribute a variety of audio and video signals throughout your home.

Planning a home AV installation is an important first step in choosing a receiver that will support the user needs. Do you only want to connect audio components like a CD player? Or, are you considering a home theater and need connections for your television, a Blu-ray Disc or DVD player, a cable/satellite Set-Top Box, ? Will you be installing surround sound speakers? Do you want to connect to the Internet through your receiver? Answering these questions will help you determine what to look for in your home electronics purchase.

Here are some typical inputs and outputs that can be found on AV products:

• HDMI (High Definition Multimedia Interface): A single-cable digital AV interface commonly found on consumer products for the transmission of high definition and standard definition video and multi-channel surround sound audio. HDMI also supports the CEC (Consumer Electronics Control) interface, which when implemented properly can allow various home theater components to communicate and control each other.
• DVI (Digital Visual Interface): A digital video interface that is compatible with HDMI (via a plug converter). DVI cables do not carry audio signal content, so separate cables are needed for audio signal connection between devices.
• Composite-video: A single-cable analog video interface used for the transmission of standard definition video signals. Composite video cables do not carry audio signal content, so separate cables are needed for audio signal connection between devices.
• Component-video: A three-cable analog or digital video interface used for the transmission of standard definition and high definition video signals. Composite video cables do not carry audio signal content, so separate cables are needed for audio signal connection between devices.

Surround sound is a movie recording technique that, when paired with a home theater surround speaker system, puts the viewer in the center of the action with sounds that move front to back, and side to side. Surround sound isn't about louder sound, rather, it is more about sound that envelops the listener by creating ambience and providing directionality to off-screen sound effects.

Surround sound is created by multiple speakers linked by a receiver. However, the easiest path to take is a home-theater-in-a-box system. These systems include a receiver, built-in surround sound decoding, speakers, a subwoofer, and a Blu-ray Disc or DVD player.

Basic speakers fall into a number of different categories, but each is designed to carry a specific range of frequencies. Knowing the frequencies a speaker carries helps to pick the ideal type for the user listening needs.

Bookshelf speakers reproduce a full range of frequencies, making them very versatile. Two bookshelf speakers can be used as the sole speakers with a conventional stereo system, or with a stereo TV. Two bookshelf speakers could also be used for the front or rear speakers in a surround system. Additionally, one speaker may be used as an economic alternative to the center-channel speaker in surround sound, if it is magnetically shielded so as not to interfere with the TV picture.

Front speakers come in a variety of sizes and reproduce a wide range of sound frequencies. They are typically used in a home theater system.

Center-channel speakers are dedicated to reproducing on-screen sound and dialogue. They are placed on top or just underneath the TV, and typically shielded so they won't interfere with the picture.

Rear speakers complete the surround effect by providing background sound behind the user. They add a sense of realism to surround sound.

Subwoofers are designed specifically for bass output. They are usually placed on the floor and are "powered," which means that they have a built-in amplifier that requires an electrical power connection in addition to speaker wires. A subwoofer is critical for 5.1 surround sound.

Children's Haven

Bonjour à tous~

Happy Hari Raya to all my Muslim friends. It's the time again for forgiving and friendship rekindle. So I have visited some of my friends and colleagues and I'm impressed of what they did with their kampung house, especially their playrooms.

We all have been wanting to have a home, which we can design and decorate based on our own imagination. Imagination is greater than knowledge- by Albert Einstein. But as we keep improving our home for a better lifestyle, have we considered about our kids who stay with us?

I brought my kids to many places for holidays such as Universal Studios, Legoland, local theme parks, Lotte World, etc and most of it comes with a themed rooms that cater to our needs. So I thought, why not we make this idea at our house for the kids? Well, there are so many ideas out there, thanks to the Internet, but of course we want to build it in an efficient way. So let's see what are things that can be used for building such a room.

Designer Wallpaper

Forget about old-fashioned wallpaper with dated floral designs or fairy-tale murals. The hottest trends for playrooms include designer wallpapers that would look just as home in any other part of your home. You can experiment with color and bold designs a little more freely, such as bright oranges arranged in geometric lines or blue hot air balloons all in a row across the sea blue sky.

Don’t feel like you have to cover the whole room with this wallpaper. Covering only one wall is fashionable and helps make a greater impact. Paint the remaining walls a complementary color, or even paint each wall a different color that ties the decor together.

Decals are a good choice if you want to create a patterned wall but don’t want to ruin the drywall with wallpaper. Decals are easily removable, so they won’t damage the wall and they allow you to change the look on a whim. Picking up the right wallpapers can also save energy by reducing light intensity and air-conditioning temperature setting.

Grey & Yellow Colour Scheme

You can design your playroom in any color scheme you wish. However, the combination of grey and yellow is particularly popular right now. You can go big with the color scheme by painting the walls grey and hanging yellow curtains (or vice versa), or you can create a neutral palette with a white wall and then place accessories in the grey and yellow color scheme. A grey couch with a yellow chevron rug and yellow pillows would look lovely. Other accessories to consider include colored fabric bins for toys, lamps, shelving, and toys that are displayed on shelves. Of course with this colour, the playroom will look spacious and it's bright enough to reduce the lumens needed to light up the room.

Poufs

Poufs are like oversized bean bags, but they are a bit more stylish than the neon or tie-dyed versions you may have had in college. They are perfect for seating for a kids’ playroom because they are soft and comfortable. Kids will love plopping down in one to read or take a rest from play. They are also malleable without being damaged, so they will withstand kids jumping on them in a way that a sofa would not.

Choose fabrics like microfiber that will enhance your design while also being resistant to stains and spills. Choose oversized poufs to accommodate the adults as well as the kids. Place a couple strategically throughout the playroom, either to complement seating like a couch or to replace it. With the right choice, it may have good ventilation and will need less fan power to cool down the room.

Timeless Design

You don’t have to limit yourself to kids’ motifs when decorating your playroom. In fact, you probably shouldn’t. Children quickly outgrow their interests, and you don’t want to have to redesign your playroom every couple of years (if not more frequently). Choose a Hello Kitty theme now, and you’ll likely be trading it out with One Direction in another year or so.

Instead, choose a more “grown up” design that will remain stylish over time. Make the room accessible and comfortable for children, but choose a design that is more attractive to a larger audience. Choose solid colors for the walls, colors that won’t look out of place with the design in the rest of your home, and designer furnishings. Make sure you include functional pieces, as well, such as plenty of shelving for toys, ottomans and low shelving, and baskets and fabric bins.

You can even add in some smart TV for their entertainment and educational view. Maybe some smart tablet embedded in the wall for them to use it as learning and playing at the same time.

Playrooms offer an opportunity to create a fun yet stylish space in your home. You can provide a fun place for your children to play while also helping to keep your home more organized, keeping toys out of common areas to reduce clutter. These hot design trends can give you some ideas for putting together your new playroom. You’ll create a space that looks just as stylish and put together as the rest of your home, and you can also have some fun with some different design choices.
