What We Hear, Feel and What’s Actually Going On
Vibrations from nearby mining operations can be startling. But when it comes to measuring sound and vibration, it’s important to keep in perspective what we hear, feel and what’s actually going on.
Feeling Vibrations ≠ Damage
As you can see from the chart, humans feel vibrations as low as .02 inches per second (in/s). That’s 1/25th of the safe, legal limit (0.5 in/s) used in Florida limestone mining operations, and 1/125th of the vibration levels caused by hammering a nail. If you’re feeling vibrations during or after a blast, don’t worry. Humans feel vibrations at very low levels, but those low-level vibrations can’t cause damage to homes. Blasting standards are specifically set to ensure that vibrations levels come nowhere close to the damage threshold.
How Environmental Forces Affect Your Home
Everyday environmental forces like changes in temperature and humidity, soil pressure, wind events and thunderstorms are the most likely cause of stress to nearby homes (and unfortunately, natural forces can’t be regulated).
