ThePain,
Just what .22 revolver did you want? You might be able to get one from a private party deal.
As a general rule and previously stated, it's not a good idea to shoot without hearing protection (even if you're just using the spongy disposable earplugs).
In an open air space, the .22's report from a handgun can be tolerable. A 2" barrel will make more noise than a 4" however. Moving up to almost any centerfire caliber will dramatically increase the noise.
Normal conversation is around 60 Decibels (Db)
Trucks, tractors or subway noise is about 90 Db
A rock concert and a .22 are about 120 Db
Air Raid / Disaster sirens measure 130 Db
Centerfire handguns measure in the 150 Db range
Commerical Jet aircraft taking off also are 150 Db
Keep in mind that it is the loudness of a sound (Db) and it's duration that causes hearing damage. A household blender is about 85 Db and a few seconds of that are okay. But exposure to 8 hours of that noise could cause permanent hearing loss.
Loss occurs when the hairs in the cochlea (inner ear) are bent or flattened by the pressure waves of a sound. Loud noises over 140 Db for even short durations damage the hairs. Repeated exposure results in more hairs damaged until only the loudest of noises can be sensed.
Also, the older you are the more likely you are to experience a larger reduction in hearing due to a loud noise. A single 150 Db gunshot may cause a 5% hearing reduction in a teenager, but a 10-15% loss in a 50 year old. And damage is cumulative. That is, exposure to loud noises slowly "wears out" your hearing. A teenager playing loud rock music or attending a lot of concerts could end up at 21 with a hearing loss equivilant to the average 50 year old.
Protect your eyes and ears. You're only issued two!
