My wife is pregnant with our third child(a boy I hope lol) and we have been talking about doing some firearm training together. She said it would hurt the baby and she did not wish to do it while pregnant. I have done some research and found a few things stating the lead dust may hurt the baby among other things. I did not give any thought to sound levels till I read this.
Anyone have any thoughts on this? Did your wife shoot during her pregnancy?
Recommendations About Shooting While Pregnant
The question about whether women should shoot weapons during their pregnancy has come up in a number of contexts, recreation, law enforcement, military, secret service, etc. However, the answer is not a simple yes or no. Basic research on the topic, funded by the National Institutes of Health and the Department of Defense, indicated that fetal sheep suffer hearing loss and damage to their inner ears following intense exposures to steady-state noises and impulse sounds.
Before we go too far, let me explain why pregnant sheep were used for this type of research. Like humans, fetal sheep begin to hear during the last trimester of pregnancy. Furthermore, the dimensions of the abdomen of human females and sheep are similar, certainly more so than guinea pigs.
Scientists have recorded the sound levels in the uterus produced by noise sources outside the ewe, estimated transmission loss of sounds entering the ear of the fetus, measured the hearing of the fetus before and after exposures to intense impulses (equivalent to a howitzer - 170 dB), and studied tissue damage in the fetal inner ear following high-level exposures.
The simple message is extremely intense, long-duration exposures alter fetal hearing and produce tissue damage to the inner ear, a sure sign of hearing loss. Exposure to 20 rounds of howitzer-level impulses produced permanent damage to the fetal inner ear. Does this mean the same thing would happen to the human fetus? We don’t know the answer to that. However, it is best to be prudent. A national standards organization offers some guidance (American Conference of Governmental Industrial Hygienists).
Pregnant women should avoid steady-state noise levels over 115 dB (that’s really loud and not commonly found outside of heavy industry and the military) and impulses over 155 dB. Consequently, pregnant women should avoid shooting weapons that are more powerful than a .22 caliber rifle or pistol. It makes good sense for pregnant women to avoid loud equipment as well, particularly if their bodies come in contact with the devices.
Some organizations that require pregnant employees to qualify with their weapons are concerned about this issue and have curtailed this practice during the woman’s pregnancy. Shooting is fun and is not hazardous to unborn babies as long as one takes proper precautions.
