[QUOTE="tinkerer, post: 1187955, member: 50973"] Technically accurate, but not totally correct. We humans hear by a measurement of dB, but on a scale called the A Slow scale as we do not hear all frequencies equal. From maybe 20-30 hertz (Cycles per second) to about 2000, we hear OK. These are bass, and we feel them more than hear them. Common speech is from 2000 to about 8000 hz. We are fairly effective in this range. Higher frequencies, 8000-20000 or so in a healthy younger person, tend to be either irritating or down right painful in higher levels. So our response charted in hz vs db sensitivity tends to be kinda large J shaped. These are true if you're a young adult and have not damaged your hearing already (loud sound, concerts, earbuds, etc, etc). As we age, the response tends to eat up the edges first, finally encroaching upon that 2K-8K range. So, wear your hearing protection when shooting and hunting, exercise caution at loud events (going to the race track next week, taking the ear plugs with me), and it should last your lifetime.
