玩枪的代价: 听力损失 , 失聪
我们都知道，枪的响声，会永久性的 损害我们的耳朵。
代价是: 听力损失 , 永久失聪
Noise Levels
Both the amount of noise and the length of time you are exposed to the noise determine its ability to damage your hearing. Noise levels are measured in decibels (dB). The higher the decibel level, the louder the noise. Sounds louder than 80 decibels are considered potentially hazardous. The noise chart below gives an idea of average decibel levels for everyday sounds around you.
噪音水平
噪音量 和 暴露在噪音时间长短 确定 其损害听力程度。噪音水平衡量是分贝（分贝） 。分贝水平越高，噪音越响亮。声音超过80分贝 被认为是潜在的危险。下面 噪音表给你一个概念，和日常周围声音的 平均分贝水平。
Painful
150 dB = rock music peak
140 dB = firearms, air raid siren, jet engine
130 dB = jackhammer
120 dB = jet plane take-off, amplified rock music at 4-6 ft., car stereo, band practice
Extremely Loud
110 dB = rock music, model airplane
106 dB = timpani and bass drum rolls
100 dB = snowmobile, chain saw, pneumatic drill
90 dB = lawnmower, shop tools, truck traffic, subway
Very Loud
80 dB = alarm clock, busy street
70 dB = busy traffic, vacuum cleaner
60 dB = conversation, dishwasher
Moderate
50 dB = moderate rainfall
40 dB = quiet room
Faint
30 dB = whisper, quiet library
一个栓动枪 (Bolt action) 加 0.22小口径 再加 消声器 的声音大约是 115至120分贝。
这样的组合 应该是 玩枪 最最小的声音, 所以，不要希望消声器可以帮助您。
阿弥陀佛..... My God...... 阿拉真主....... 也不能保护你。
珍重, 请好自 为之........ ! 买一个好的耳朵保护器
