How far will the sound of a gunshot travel

The distance that a sound wave travels can be figured by multiplying the speed of the sound (approximately 345 meters per second under normal atmospheric conditions at a temperature of 20 degrees Celsius) by the time it takes for a person to hear it once the sound is initiated. The chart below shows different types of power tools and their noise levels. Changes in materials, temperature and air pressure can speed up or slow down a traveling sound wave.

Duration is typically measured over a workday and accumulated through many years.

The noise level is therefore expressed in decibels (dB) on the 'A' scale, or dB(A).Дuration of exposure is equally important. Most workplace noises include a wide band of frequencies and are measured through the 'A' filter in sound-level meters. Sounds must also be specified in terms of frequency or pitch. Hearing protection should be used for any level over 85 dB and double protection for any level over 105 dB. In other words, sound intensity doubles every 3 dB. But 93 dB is still twice as much noise as 90 dB. A sound 1,000 times more powerful than near total silence is 30 dB.ДЇor example, a backhoe and a compressor each producing 90 dB have a combined output of 93 dB, not 180. A sound 100 times more powerful than near total silence is 20 dB. On the decibel scale, the smallest audible sound (near total silence) is 0 dB. Some Montrealers way home from work on Monday night was disrupted by the sound of an apparent gunshot inside Peel metro, which is not exactly what you hope to hear after a long days work or you know, ever. But on a more serious note, please never fire guns into the air, a surprisingly high number of people get killed by bullets fired during celebrations all over the world, such as new years in the US, or sometimes weddings in the middle east. This means that noise levels can't be added directly like other numbers. But it does do a good job of capturing the sound very realistically.

The decibel scale is not linear but logarithmic. Decibel (dB) is the unit used to measure a sound's strength.
