How danger ⚡️ are firecracker 🧨 explosions

✅ Firecrackers are used all over the world 🗺️ during New 🆕 Year’s Eve, some festivals and ➕ to celebrate 🥂 different social as well as religious occasions. Explosions of firecrackers, especially on New 🆕 Year’s Eve, is enormous and ➕ some people 👥 are subjected to a peak sound 🔉 pressure levels 🎚️, which excide permissible level 🎚️, and ➕ can 🥫 cause loss of hearing 👂️. In many cases, firecracker 🧨 explosions present 🎁 a source of annoyances and ➕ stress-related diseases, so for people 👥 as well as for wild and ➕ domestic animals. In addition, they 🎁 a 🔥 hazard ➕ risk of 💻️ injuries (🔥 of 👃 ➕ 😀, loss of sight ➕ 👆️). The number of 🧨 explosions ➕ a peak 🔉 pressure distribution are the main parameters influencing on the place of immission, there hazard and risk of personal injuries (burns of body and face, loss of sight and fingers). The number of firecracker explosions and a peak sound pressure distribution are the main parameters influencing on the place of immission, therefore some statistical properties were observed. A special emphasis is given ⬅️🎁 to the joint probability density distribution of the peak sound 🔉 overpressure levels 🎚️, originating from a great number of firecracker 🧨 random 🔀 explosions. Investigations have shown that in case of the high enough number of explosions in unit time ⏱️, the Rayleigh distribution tends to a Gaussian one 1️⃣.
