Increase Microphone Volume in Windows

From the Taskbar, right-side, right-click on the ‘Sound’ icon and from the options displayed select ‘Sounds’.

Right-click on the active microphone. The active microphone has a green check-mark marked against it. Depending upon the setup there may be multiple microphones present.

Again, right-click the active mic and select the ‘Properties’ option.



Then, under the Microphone Properties window, from the ‘General’ tab, switch to ‘Levels’ tab and adjust the boost level.



By default, the level is set at 0.0 dB. You can adjust it up to +30 dB using the slider provided.

Be sure to carry out the process during your conversation so that you get the feedback from the other end immediately. This will also tell you whether the adjustments made are appropriate or not.

Microphone volume too low

In rare cases, it has been observed that boosting the microphone volume may not solve your problem. If it is so, select the ‘Advanced’ tab from the ‘Microphone Properties’ window instead of ‘Levels’ and uncheck the option that reads as ‘Allow application to take executive control of this device‘.
