Sound effect (acoustic energy) of normal lightning storm is spreading in 2D environment - its volume decreases with the square of the distance, and therefore much slower, than in the case of the BFTB, when the sound is not reflected many times between clouds and the ground and decreases as the cube of the distance, and in addition is a substantial part diverted by upward expanding lightning channel straight up and has not any possibility to bounce back from anything (no clouds).
Sauti athari (akustisk nishati) ya dhoruba ya kawaida ni kueneza umeme katika mazingira 2D - kiasi yake itapungua na mraba na umbali, na kiasi polepole hiyo, joto kama katika kesi ya BFTB, Wakati Sauti Je hawafikiri mara nyingi Kati ya mawingu na ardhi na itapungua kama Cube na umbali, na katika addition ni sehemu Kikubwa avledas kwa kupanua zaidi umeme channel sawa sawa juu na hana lolote Uwezekano Bounce nyuma kutoka kitu chochote (hakuna mawingu).
