Each method has its benefits and drawbacks, but all are effective, particularly when used in combination. Double glazing offers the best insulation but the main concern is with the cost involved.
Double glazing windows involve fitting the window frames with two panes of glass leaving a spacing of 12mm — 16mm in between. The space between the frames and panes is sealed to make it airtight and the dead air in between acts as a very effective insulating area. Below is a chart which compares the soundproofing effectiveness in terms of STC Sound Transmission Class of normal single pane, laminated and double glazed windows. The mean values of STC of the three types are as shown below.
The effect of each STC value is given in brackets as per information from Wikipedia. As you can see, double glazed windows make a huge difference but as mentioned earlier, they cost a lot.
This is by far the simplest answer to the problem of window noise. Window plugs are easy to build, are made from inexpensive materials, and are highly effective. They work by filling in the space in front of your windows with layers of acoustic foam, soundproof matting, and wood. The foam at the front absorbs incoming sound waves. Any noise that makes it through the foam is blocked by the mat and the wood backer board.
Handles are added to the back surface of the wood to allow easy installation and removal. They can be added when needed and pull out when not. Plus they block all incoming light. To build a window plug you need to first measure the height, width, and depth of your window opening. Make your plug slightly wider and taller than your window opening to ensure a tight seal. The window depth measurement is important because it will determine how thick your plug can be.
To build your barrier, cut your acoustic foam, soundproof mat, and wood board either plywood or MDF works well to a size slightly taller and wider than your window opening. Then glue the mat to the wood and the foam to the mat.
You can screw metal drawer pulls to the back of the wood board to function as handles. Once the glue is dry, simply press the plug firmly into your window opening, leaving a small gap between the foam and the glass. A more detailed way to build a window plug can be found in my article here. To do this properly you should temporarily remove the trim from around your windows. This will give you access to the outside edge of your window frames.
Fill in any cracks, holes or gaps with a quality acoustic sealant. Acoustic sealants are specially designed polymers that fill holes and prevent sound vibrations from propagating through open air. This method is also good to use in conjunction with other methods for extra sound protection. Like a window plug, soundproof curtains are fairly easy to install, particularly if you already have existing curtain rods.
Unlike a window plug that both absorbs and blocks noise, curtains can only absorb. On top of this added bit of noise absorption, they can make ugly solutions like window plugs more attractive by hiding them behind curtains. One method for making soundproof curtains more effective is to buy them longer than you need so that you can fold them over to add another layer and increase the thickness of coverage.

If you have multiple 5mm jacks to plug into, especially on a surround sound system, make sure all cords and cables are plugged into the correct jack.
Note : Some systems use a green jack for output and pink for mic input and others will be labeled "headphone" or "microphone. It's possible that your speakers won't work when your headphones are plugged in. Unplug your headphones and see if that helps.
Right-click the Speakers icon on the taskbar, and then select Open Volume mixer. Make sure none of them are muted. In that case, select the volume control to unmute. Check your device properties to make sure that your devices have not been disabled by mistake. Select your audio device, and then select Device properties. Be sure to select Device properties for both the output and input devices.
Make sure the Disable check box is cleared for the output and input devices. Hardware problems can be caused by outdated or malfunctioning drivers. Make sure your audio driver is up to date and update it if needed. If that doesn't work, try uninstalling the audio driver it will reinstall automatically. If that doesn't work, try using the generic audio driver that comes with Windows. If you're having audio issues after installing updates, try rolling back your audio driver.
In the search box on the taskbar, type device manager , then select it from the results. Select the arrow next to Sound, video and game controllers to expand it. Right-click the listing for your sound card or audio device, such as headphones or speakers, select Update driver , then select Search automatically for updated driver software.
Follow the instructions to complete the update. If Windows doesn't find a new driver, look for one on the device manufacturer's website and follow those instructions. If that doesn't work, try uninstalling your audio driver. Right-click the listing for your sound card or audio device, select Uninstall device , select the Delete the driver software for this device check box, and then select Uninstall. Note: Be sure to save documents and any other current work before you restart.
Select the audio device whose driver you want to update, select Next , and then follow the instructions to install it. Following is an example of a driver download page for a sound device manufacturer. Right-click the listing for your sound card or audio device, then select Properties. Select the Driver tab, then select Roll Back Driver. Read and follow the instructions and then select Yes if you want to roll back your audio driver.
If rolling back your audio driver didn't work or wasn't an option, you can try to restore your PC from a system restore point. When Microsoft installs updates on your system, we create a system restore point in case problems arise.
Try restoring from that point and see if that fixes your sound problems. For more info, see "Restore from a system restore point" in Recovery options in Windows If you're connecting to an audio device—such as headphones or speakers—using USB or HDMI, you might need to set that device as the default audio device. You can check that when you set your default output audio device.
In the search box on the taskbar, type control panel , then select it from the results. On the Playback tab, right-click the listing for your audio device, select Set as Default Device , and then select OK.
