A. Check the app settings for an option to mute the shutter sound. If there is no such option, consider using your device's volume controls to lower the media volume before scanning. This may help in reducing or eliminating the shutter sound during the scanning process.

B. If muting the sound is not possible, try using a different scanning app that allows for silent scanning, or use the device's 'Do Not Disturb' mode to minimize sound interruptions.
