Answer 1

Edit......Wallmart has mini air horns in the boating section. They are loud as heck but you wont go deaf unless you point it in your ear and hold it on. They can be heard a mile or so. This one is 120db

Wow, there's a lot of bad answers on here. First of all, noise induced hearing loss is cumulative, so while one exposure to a moderately-intense sound will most likely not instantly make your child deaf, all those single exposures add up. Truck drivers, for example, can get hearing loss because of the sound of the the engines and air rushing past their heads through an open window, and there are MANY cases of people getting hearing loss from loud personal music players (such as iPods). A disturbing trend lately is that noise-induced hearing loss is showing up at younger ages because of such environmental sounds we expose ourselves to at young ages, like the personal music players and video games, etc. Exposing your child to 90+ decibles of sound daily or weekly could add up to noise induced hearing loss early in life (this is starting to show up in teens and twenty-somethings now, as opposed to the past where it didn't tend to show up until people were in their 40s). When you say that the sound "seems" louder indoors, you're right. It actually is louder, becuase it is echoing off the walls and cieling. One exposure can affect a person's hearing, either by adding to the cumulative effect of noise, or causing an instant loss if the noise is loud enough (you see this more with gunshots and explosions). With all that said, I wouldn't freak out about vacuuming around your baby once or even a few times. I doubt you've had a significant impact on your baby's hearing at this point. The best idea is to avoid having your baby in the same room as much as possible; vacuum the rest of the house while he's asleep, and vacuum her room while he's with someone else or otherwise safe in another room. If you're worried about your baby's hearing for any reason, or if you want some educated answers, visit a local audiologist. Pediatric audiologists have the equipment and expertise to assess the hearing of children as young as one day old.

Answer 5

Most of them run around 110-120 DB and can be heard a 1/4 mile away or more. Just get one small enough to carry. Some units have a flashing strobe light as well. Check out some sites that offer personal protection devices or call your local police for info.
