Automatic noise cancellation
To minimise the surrounding noise during an important video call on Google, you can turn on the automatic noise cancellation feature. All you need to do is follow a couple of steps before joining the meeting. Just go to the 'More' option in the top right corner and then go to Settings > Audio. Now, turn on Noise cancellation, and join the meeting.
Blur or change background
If you think your background is not good enough to be on a work call, you can choose to blur the background or change it altogether. Just tap on Apply Visual effects option in the bottom right of your self view. To completely blur your background, click Blur your background. To slightly blur your background, click Slightly blur your background. Before joining the meeting, select a pre-uploaded background, click a background. If you want to upload your own image for your background, click Upload a background image, add an image. You can also choose the filter and style of the background.
