By default when you close a tab in Google Chrome you will hear a slight clicking sound. If this is bugging you then it’s very simple to turn off.
In Windows 7 go Start>Control Panel>Sound (in XP this is Sounds and Audio Devices)
Under the Sound tab, scroll to the bottom and you will see Start Navigation (just above Windows Speech Recognition) Select this and then use the drop down menu below Sounds: and choose None (at the top of the list)
Hit OK.
That’s it.
