How loud is 111 decibels?
111 decibels is about as loud as a chainsaw, shouting or barking directly in the ear, a sonic boom. That is at or above the 85 dB hearing-risk line: NIOSH limits safe exposure to about 1 minute a day, and every 3 dB louder halves that. On the decibel scale, each 10 dB step sounds roughly twice as loud. Measure it yourself with Decibel Shield's free online decibel meter.

In open air a small source measured at 111 dB from 1 m falls to about 91 dB at 10 m and 71 dB at 100 m, losing 6 dB each time the distance doubles. You keep hearing it while it stays above the background level around you: farther in a quiet field at night, much less on a 60 dB street. Walls, ground and wind change the figure.
