Sound Insulation Testing

The purpose of sound testing is to make sure your setup has acceptable level of impact and airborne sound insulation based on the building regulations in your area. You may have to meet the requirements in order to make sure that your building is totally compliant. Let’s know more about it.

What is tested?

The number of floors and walls that are going to be tested depends on the type and quality of the building in addition to the construction method. As a matter of fact, the number of tests change based upon the number of buildings as well as the quality of the buildings.

Is your building ready?

Before you hire a sound testing service, we suggest that you make sure that your building is ready for the performance test. In other words, the doors and windows should be installed and closed. The ventilation systems should also be properly installed. Apart from this, the light switches, sockets and skirting boards should also be in place.

Sound testing cost

Most providers offer valuable services for the fees paid. You may want to look for a service provider who gives importance to their clients. The “site fee” includes the reporting, equipment and engineer’s fees. Usually, each of the tests is charged separately in order to cut down on your expenses. Moreover, for bulk testing, you can get special discounts. So, the cost will vary on the basis of the number of rooms that you want to get tested.

Failed tests

If a test fails, the company may offer a free of charge re-test or design service. It’s important to keep in mind that the engineer may let you know if the test is going to fail. In fact, the tests fail rarely. Experienced acoustic consultants review the buildings and give advice on inexpensive solution so you can achieve the highest standard. Remember: remedial works may cost you a lot of money. Therefore, you may want to get the work done well in first attempt.

Airborne testing

The purpose of an airborne test is to measure the resistance that the sound goes through when passing through a floor or wall. Actually, it uses an omni loudspeaker which is put on a side of the wall or floor. This system produces pink noise.

Impact Testing

This is another common type of sound testing. In the impact testing, the tests are done with a tapping machine that looks like a football. And this machine is rested on the top of the rooms and the noise is measured. Then the level measured is corrected based on the reverberation time of the noise in the background as well as the time. This gives an accurate result of the impact sound insulation.

Audio Visual Receiver

So you have settled down to watch the latest big-screen movie on your massive HD/plasma/3-D TV… You grabbed the bag of hot cinnamon caramel popcorn, a cold one to drink, gathered the family and watched the movie. Somehow, the picture and sound quality just wasn’t quite as good as you thought it would be and you realized, that, despite owning an expensive TV, the sound and visual effects just didn’t quite cut it. This is where an audio visual receiver (AV receiver) makes the home cinemas experience a fully immersive and richly satisfying occasion.

An audio receiver functions as the hub of a home theatre system by handling a variety of tasks, such as decoding the signals for surround sound, tuning to radio stations, powering up speakers and switching between audio and video components.

Here are the 5 most important things to look for when choosing the best audio receiver.

1) A High Tech Audio Visual Receiver Or Not…

You may think a cutting edge, high-tech audio receiver is the best thing possible, but stop right there. You need to be able to figure out how to use it! The display panel must be easily navigable so you can enjoy concert hall quality sound and movie quality pictures, rather than the audio receiver gathering dust because you can’t figure out how to turn it on.

A good quality receiver will usually include a graphical interface through which the user can set up and operate the receiver. All the information will be clearly displayed so you can figure out how to navigate and use the unit.

2) Calibration: Is The AV Receiver easy To Calibrate?

If you are a novice, setting up a home entertainment system so that all the components are correctly connected can be tricky, let alone working out whether the components are all functioning correctly.

Most of the best audio receivers make this part a bit easier by offering automatic speaker calibration, allowing the receiver to analyze and automatically adjust the sound of the connected speaker system.

The receiver sends test tones to the speakers and sub woofer, monitoring the sound using a microphone so it can determine speaker size, measures the distance from each speaker to the listener and check whether the components are properly connected.

This technology works for the traditional 2 channel home entertainment system as well as for the surround sound home cinema theatre.

An important note here is, the powerful sound bursts in a high action movie and other special effects can drain the receivers power if it is not a high current power audio visual receiver. A high powered unit will produce the high quality movie sounds better than a similar receiver that doesn’t have high current power, even if it has the same wattage.

3) Is There Airplay Compatibility Available?

These days the best audio receivers will have AirPlay compatibility which is the latest technology allowing users to wirelessly stream music from an iOS device ( Apple) as well as digital apps such as Pandora. This allows you to stream directly to the receiver.

Make sure the version of iPhone, iPad or iPod you own has integrated wireless streaming capabilities before you get a receiver with AirPlay technology.

4) Power: Make It High Wattage

Power isn’t just another word for volume, power is measured in watts. More importantly, it determines an audio receivers ability to reproduce dynamic and detailed sound. A high wattage unit will provide better sound quality over those with less power, even at the lower and medium volumes of the movie.

It’s vital the receiver is powerful enough to accommodate both the speakers that are connected to it and the room where the receiver is located. Depending on the speaker sensitivity, the power needed to match the specific speakers will depend on the number of decibels it puts out per watt of power.

You’ll find that speakers with lower sensitivity will require more power. Make sure you take into account the size of the room. If the room is a large one in which an entertainment system is set up, more power is required.

Another point is take into account on how much power will be needed, is whether you are looking at a home theatre or stereo receiver.

The stereo receiver is a simpler and less expensive unit for music lovers who aren’t necessarily looking for a cinema surround sound experience. A home theatre audiovisual receiver is designed to create a fully immersive, surround sound experience for users to enjoy.

5) Last But Not Least: AV receiver Inputs and Outputs

This is a simple one. The more inputs and outputs the device can accommodate the better. These inputs and outputs are where you connect to the receiver with your TV, gaming system, iPod or speakers. You need to have enough inputs and outputs to handle all your equipment easily, plus a few extra for just in case.

And whilst a good number of inputs and outputs are important, you must make sure they are the right kind. The audio receiver should offer digital connections, providing better video and audio quality than the more dated analogue inputs and outputs. To get the most enjoyment out of your HD equipment it should be connected to a receiver using an HDMI (Hi Definition Multimedia Interface) connection.

Choosing the best audio visual receiver for your home theater cinema experience which will bring you the best of movie and sound enjoyment for years to come is a step to be taken with careful research. Choosing an AV receiver with all the above qualities will ensure you will be happy with your purchase, particularly if you are spending a fairly large amount of money.

Multi-Room Audio

Why Choose a Whole House Audio system? Most people choose to have a whole house system because it allows them to take their music and audio with them regardless of which room they happen to be in at the moment. A whole house system allows you to carry on your life without being plugged into an iPod. You can have conversations with your children, spouse, and guests while listening to the ball game or your favorite tunes. What is on your honey do list for this weekend? You have to clean out the garage. No problem. You can take your music with you. You have to do all of the yard work too? No problem, take the game outside and listen while you work. A whole house system allows you to go about your life and still be able to do the things you want to do like just listening to the ball game.

What are my Choices?

The two big choices are single source systems or multi-source systems. Those can be set up as a wireless audio system or hardwired. The biggest difference is in the quality. The quality of the audio you receive goes up tremendously with professional installation. One consideration is the fact that every room in your home has different audio needs as each room responds differently to sound. A professional will be able to recognize the acoustic requirements of every room in your home.

Features include wall mounted volume dials that allow you to instantly adjust the volume of your audio specifically for that room. Most systems allow you to turn rooms on or off with a remote. No use waking your neighbors up at 3 am when you start to watch Jurassic Park and the outdoor system is streaming dinosaurs fighting. Streaming music is another option with built in iPod docking stations that allow the contents of your iPod to be played over your whole house system or multi-room audio system.

Components:

There is a variety of complete audio packages. These pre-configured systems include speakers, wire, keypads, and everything else you need to set up a multi-room audio system. You can build your own system or allow one of our pros to help you select components that fit your audio needs. Start with an Amp and Keypad package or individual components. From there, you can add in power amplifiers to build a custom sound. Speaker selectors allow you to control which rooms receive audio and when. These allow you to control the overall sound throughout your home. Speakers are another area where choice plays a large part in the quality you receive. A professional installation will allows you to add speakers in your ceiling and even add in-wall units. The type of speakers that you choose makes a difference. Wireless setups allow you to broadcast audio without installing wires. These can afford an advantage to really customizing speaker location. Audio components allow seamless streaming of audio via Cat5 cables.

New Builds and Retrofit

It is obviously easier to install a multi-room audio system during construction, but most of us are not building a new home. That means either using a wireless audio system or installing wires. That is where a professional installer comes in handy. Not only do they understand how to run wires the correct way, they know where wires should go and how to hide them. They can also make sure that all of your components are installed correctly and that all systems are working. They can even give you an overview of how to use the system.

There are a lot of advantages of having a whole house system. The systems range from simple to complex, but the grade of sound should always be professional. When you decide you want home audio choose your components carefully. Working with a professional can make a huge difference in the quality of the audio you receive. Understanding that not every room in your home is going to respond the same way to audio is important. By customizing speaker selection to each room, you gain a huge advantage in the quality of the audio that each room receives. No more popping and crackly connections.
