Sound always need a medium to travel whther it be solid, liquid or gas. If we use several layers to build a shield, sound may not be able to penetrate. But it depends on the nature of the sound too. The audible sound which we can hear will not able to penetrate through several layered structures. But high frequency ultrasonic waves can penetrate even cement blocks.
Ultrasonic cleaning is cleaning through ultrasonic waves with some chemicals.
An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.

What?! Trace ultrasonic waves? Are you one hundred per cent cuckoo?! Why would anyone trace ultrasonic waves these days??

industrial applications of ultrasonic waves: 1. ultrasonic welding 2. ultrasonic cleaning. 3. ultrasonic drilling. 4. ultrasonic soldering. +++ 5. Flaw detection in metals etc. And many others if you stretch the term "industrial to include, say, medical!
Ultrasonic sounds are sounds that are above our hearing range.
