How far away can a grenade be heard?

Grenades are very loud. You can hear them from miles away under fairly typical conditions. You can also basically ignore them as background noise until you’re surprisingly close to them.

How loud is a grenade blast?

Upon detonation, it emits an intensely loud “bang” of 170–180 decibels and a blinding flash of more than one million candela within 5 feet (1.524 meters) of initiation, sufficient to cause immediate flash blindness, deafness, tinnitus, and inner ear disturbance.

How loud is a hand grenade?

There are different kinds of grenades, but for simplicity, I will give you the link to a handy little report. In that report it lists an M26 grenade as having a level of 164.3 dB at 50 feet. The threshold for pain is listed at 140, and the human eardrum tends to rupture at 195.

How far is it safe to throw a grenade?

You aren’t completely safe at any distance you can throw the grenade. In basic, we were taught that the average soldier can throw the grenade about 35 meters and it has a ‘burst’ radius of 40m. Wikipedia reports injury at 15m, fragments at 250m, fatality at 5m.

How many decibels does a grenade hit a house?

Windows and doors will be a bit worse, and windows can be knocked out by grenade fragments, considerably reducing their ability to block sound. So the noise of a grenade might lose 90–100 dB (or more) just to the house, leaving aside the issue of distance attenuation.

Is it possible to set off a grenade without hearing it?

Certainly, if you want to avoid calling attention to yourself, there is basically no “safe distance” from possible listeners at which you can set off a grenade. But it is far from guaranteed that, just because you didn’t hear a grenade go off, it didn’t happen within distances that can be alarming.

What is the maximum radius of a grenade?

So, for most commonly used offensive grenades, maximum radius of shrapnel spread is under 25 m with guaranteed kill zone of around 3 m. These grenades kill mostly via explosion itself and by a very localized burst of small splinters.
