Description	Čtyři velmi rychlé meteory zaznamenané ve velkých výškách (Leonida, 2 Perseidy a jeden sporadický bolid) byly zachyceny kromě optického oboru celooblohovými bolidovými kamerami také akusticky pozemními infrazvukovými a seismickými detektory. Infrazvukové záznamy pořízené z velkých výšek přes 100km jsou velmi vzácné a dosud byly pozorovány jen pro navracející se kosmické lodi. V této práci jsou uvedena jak data od všech 4 bolidů tak i analýza infrazvukových a seismických záznamů a kvantifikace těchto jevů. (cs) Four very high-velocity and high-altitude meteors (a Leonid, two Perseids and a high-speed sporadic fireball) have been unambiguously detected at the ground both optically using precision all-sky cameras and acoustically via infrasound and seismic signals. Infrasound arriving from altitudes of over 100 km is not very common, but has been previously observed for re-entering spacecraft.This, however, is the first reported detection of such high-altitude infrasound unambiguously from meteors to our knowledge.
