Jan 04, 2011 · The speed of sound traveling through air at sea level is said to be around 760 miles per hour, or 1,115 feet per second, so Mach 2 works out to roughly 2230 fps. Hornady rates the itsy bitsy cartridge at 2100 fps, so if we flatlanders want to be technically correct, we would call it the ".17 Mach 1.9" or something like that.

The chart is wrong. It's confusing decibels with Bels and also confusing sound pressure level (SPL) with perceived volume. 3 decibels is a doubling of SPL (power, wattage, energy ,etc.), but the perceived volume is only slightly louder. 3 dB is usually considered the minimum discernible difference for the average person.

Jul 24, 2020 · N= Noise Level The SNR is typically measured in units of decibels (dB), a unit of measure that some think is used by electrical engineers primarily to confuse computer scientists. The SNR, measured in dB, is twenty times the ratio of the base-10 logarithm of the amplitude of the received signal to the amplitude of the noise.
- Noise levels at gunner positions are low to moderate. - The hazard can be serious because of the large number of rounds that can be fired by the individual shooter. - Noise levels are higher in front and to the side of the muzzle than to the rear. For small arms levels at about 5 feet to the side can be higher than at the shooter position.
