Gladly. You see, decibels are a form of measuring sound waves. Sound waves are energy. 1100 decibels is enough energy to warp space-time around it and form such a dense collection of matter in a small space a singularity would form. This is more frequently known as a black hole. Of course, it would be rather small, only about the size of a neutron, but it would weigh 5 kg. However, it is so small Hawking Radiation would destroy the black hole in a matter of seconds. However, generating such a loud sound is impossible in Earth's dense atmosphere, we would need a 100% vacuum to do so. Yelling so loud is also impossible to do so with your vocal cords, and they won't function in a vacuum. You may think, "What if I wear a spacesuit?" Well, oxygen atoms in the suit you need to breathe are not a vacuum at all. In all, it would be impossible to create a black hole with sound. Now, I just spent half an hour researching and writing this, so you had better be grateful for this.
