How to Turn Off the Noises That iTunes Makes
Apple's iTunes software allows users to download, manage and sync music, movies and podcasts. The program is designed to make a sound when the program has been launched, or an action has been completed, such as downloading a song or syncing music to a device. Turn off the noises that iTunes makes to enjoy the program noise-free.
Click "Start," then "Control Panel."
Type "sound" into the search box at the top of the Control Panel and press Enter.
Click the "Sound" link from the Control Panel. The Sound properties window launches.
Click the "Sounds" tab.
Scroll down the list of available sounds in the "iTunes" section. There are two sounds associated with iTunes: "Complete" and "Page Load Complete."
Click the iTunes sound that you want to turn off.
Select "None" from the drop-down box under "Sounds." Click "Apply."
Repeat Steps 6 and 7 for each iTunes sound that you want to turn off.
