Locate and right-click on the Sound icon in the taskbar (represented by a Speaker icon).
Click on Recording devices.
Locate and right-click on your computer’s active microphone. Depending on your setup, there may be more than one microphones present in the Recording tab of the Sound window, but your computer’s active microphone will have a green check mark next to it.
Click on Properties in the resulting context menu.
Navigate to the Levels tab.
First and foremost, turn the slider under the Microphone section all the way up to make sure that the microphone’s volume is set to 100, no less.
If increasing the microphone’s volume to 100 isn’t enough to get the job done or if the microphone’s volume was already set to 100, you can ahead and add some Microphone Boost to the mix as well.
*The Microphone Boost feature can give a boost of up to 30.0 dB to the volume of your microphone – all you need to do in order to use this feature is select just how much of a boost you want your microphone’s volume to get using the slider under the Microphone Boost option. When tinkering around with the Microphone Boost feature, is it best to be in communication with another person via the same microphone you are applying the Microphone Boost to so that you can ask the other person for feedback pertaining to the mic’s volume at the same time you adjust it.
Once done, click on Apply and then on OK.
Click on Apply and then on OK in the Sound window to close that as well.
I’ve noted the boost with a *. If you can’t find the Db boost under Windows 10 then chances are it has been removed.
