How loud is 97 decibels?
97 decibels is about as loud as a hand drill, a stock car race, a motorcycle. That is at or above the 85 dB hearing-risk line: NIOSH limits safe exposure to about 30 minutes 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.

How far away can you hear 97 dB?
In open air a small source measured at 97 dB from 1 m falls to about 77 dB at 10 m and 57 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.
