Additionally, the security tags on items are usually deactivated at the checkout counter using a special device, allowing customers to leave the store without setting off the alarm. **

Light does not make a sound when it breaks the sound barrier because light does not require a medium to travel through, unlike sound.

Additionally, light is an electromagnetic wave, not a mechanical wave like sound, so it does not produce vibrations that can be perceived as sound. **
