I don't remember the exact numbers... but I do remember hearing that high-vel IS loud enough to cause hearing loss.

"22 lr standard vel. when fired from a rifle produces an average of 92 decibles"


Though I notice a big difference based on action, bolt action (closed) is noticably quieter than open (semi auto, like a 10/22)...


I use hearing protection for everything except 22 subsonic in my bolt action... but I usual do just out of practice.

Here's a short list of Environmental Noise decibel ratings:

dB Environmental Noise

10 Normal breathing
50 Interior home noise
70 Crowded restaurant
80 City traffic
85 Hearing Damage Possible
90 Lawn mower
120 Threshold of Pain
120 Siren
130 Jackhammer
140 Jet engine at takeoff
152 .22 pistol
156 12 gauge shotgun
157 .45 ACP pistol
160 9mm pistol
164 .357 Magnum revolver

Always where hearing protectin. Plugs and muffs are best. Even when hunting squrriels throw in a pair ear plugs. If you take five- ten shots from a shotgun, it will hurt your hearing. I would certainly want protection.

Dan

PhoenixIII, you must be thinking the same as me, that those numbers don't look right. Having served on B-52 bombers, I believe that even an idling jet engine would be far noisier than a 22 pistol.

Decibel Levels Around Us

Gentlemen,
NOISE LEVELS IN OUR ENVIRONMENT FACT SHEET

How Loud is Too Loud? Experts agree that continued exposure to noise above 85 dBA over time, will cause hearing loss. To know if a sound is loud enough to damage your ears, it is important to know both the loudness level (measured in decibels, dBA) and the length of exposure to the sound. In general, the louder the noise, the less time required before hearing loss will occur. According to the National Institute for Occupational Safety and Health (1998), the maximum exposure time at 85 dBA is 8 hours. At 110 dBA, the maximum exposure time is one minute and 29 seconds. If you must be exposed to noise, it is recommended that you limit the exposure time and/or wear hearing protection.

Measure Up and Turn it Down: "Decibel Levels Around Us" The following are decibel levels of common noise sources around us. These are typical levels, however, actual noise levels may vary depending on the particular item. Remember noise levels above 85 dBA will harm hearing over time. Noise levels above 140dBA can cause damage to hearing after just one exposure.
