Skype is a widely used VoIP service that helps millions keep in touch
with friends, family and colleagues with it’s free voice chats, video calls and conference calls.
But let’s face it, calls with unwanted noises can be a real nightmare, especially when they drown out your
But fear not, following the tips and techniques below will help you reduce unwanted noises in your Skype
calls and get you closer to the utopia of crystal clear audio.
Wearing a pair of headphones prevents your microphone picking up audio from your computer or voices of
In worse case scenarios, the sound is amplified and passed in and out, over and over again, resulting in an
unpleasant loud squeal or screech (scientifically called the Larsen effect).
While Skype does apply algorithms for echo suppression and cancellation to outgoing audio, nothing is as
effective as plugging in a pair of headphones to eliminate the source of that echo.
If you can’t use headphones, try to get as much distance as possible between your speakers and microphone to
minimize any feedback.
Take a look around you at your surroundings. Small changes can be hugely effective in stopping noise getting
to your microphone.
Try to take steps to eliminate or minimize noise from environment. This is highly dependant on where you
are, but here are some ideas to help you get started:
Just like your environment, setting up your microphone optimally can make a huge impact.
Microphones come in many shapes and sizes, and we’ve outline tips based on which type it is below.
Every microphone has a property known as directionality. This indicates from which direction and angle the
microphone best picks up sound. Some microphones even include controls on them that let you change the
If your microphone is unidirectional or cardioid (picks up sound more from one direction) positioning can
You want to position the microphone so that it faces towards you, while any potential noise sources
(keyboard, mouse, computer fans) are behind it.
See the image to the right for an example of this in practice.
See the image to the below for an example of this in practice.
This will maximize the volume from your voice, and minimize the sound from the noises.
Not sure what your microphone’s directionality is? Try googling the name of the microphone with the keyword
“directionality”. Most manufacturers will disclose that information.
Desktop microphones can be very susceptible to vibrations. Knocking the desk can result in an loud unpleasant
thud. To reduce this, try and ensure the microphone is mounted on a stable surface. A wobbly desk is more
likely to transmit vibrations, even from small things like resting your hands or moving your mouse.
Tightening screws, or even ensuring the desk is on a carpet can help reduce those vibrations.
An accessory that helps isolate microphones from vibrations is called a shock mount. For most cases, these
are overkill unless the problem warrants it (maybe your downstairs neighbour’s washing machine shakes the
floor). They typically cost between $10 to $30. If you are feeling crafty, there are a variety of DIY solutions
out there you could try.
Headset microphones typically suffer less from background noise issues as the microphone is closer to your
mouth. However they can be more susceptible to breathing and plosives noises.
To prevent this, ensure the headset’s microphone is positioned just past the corner of your mouth. Not in
front of your mouth or nose.
The microphone will still be able to hear you clearly, but avoid any plosive distortion from breathing.
Windows 7, 8 and 10 come with the options to apply various noise reduction algorithms to your microphone.
However, these are only possible if your sound card supports them (which you can
only can tell when you reach Step 4).
These can also affect the quality of speech, so experiment with these setting to see if they work for you.
We built Noise Blocker to help deal with a wide range of unwanted
noises without affecting speech quality.
Noise Blocker is an easy to use noise gate, which can be quickly
configured to block out any sort of noise (background, fans, keyboard typing, etc).
Download and install Noise Blocker, then follow
the instructions below.
Note: If you prefer, you can watch a
video of how to set up and configure Noise Blocker in under a minute.

In Skype, we need to switch to use Noise Blocker's virtual microphone.
And that's it!
