Infact sound is used to destroy/break cells in labs. Not sure on the exact method but basically the cells are suspended in a solution and then a high frequency sound wave is passed through the solution which causes the cells to break up. Althought this wouldn't occur in air as air doesn't conduct sound as well as a liquid would.
Prehaps if you put the person into a large swimming pool and then played your very loud sound through underwater speakers then the sound waves would propagate well enough to cause damage. Although more likely they will shake even the best of the best of speakers to bits in seconds.

If you do the same for Human skulls, there will not only be a sound sleep, but a sound death too. Is that possible?

Yes, it is possible for a glass to break if a loud sound is emitted near it. This phenomenon is known as acoustic resonance and occurs when the frequency of the sound matches the natural frequency of the glass, causing it to vibrate and eventually break.
The sound does not necessarily have to be extremely loud in order to break a glass. It primarily depends on the frequency and duration of the sound. A high-pitched sound at the right frequency and duration can cause a glass to break, even if it is not very loud.
Glasses that are thin and have a smooth surface are more likely to break from a loud sound. This is because they have a higher natural frequency and are more susceptible to vibrations compared to thicker and rougher glasses.
Not all sounds have the potential to break a glass. The sound must have a specific frequency and duration in order to cause the glass to vibrate and eventually break. For example, a low-pitched sound such as a bass drum is unlikely to break a glass due to its lower frequency.
Yes, other materials can also be broken by a loud sound if their natural frequency matches the frequency of the sound. This includes materials such as crystal, ceramics, and even some metals. However, not all materials have a natural frequency that can be easily matched by a sound, making glass the most commonly used material for this demonstration.
