voyageur said:Looked around with nothing to further add other than a reference to "Infrasound" waves. According to the wiki page: https://en.wikipedia.org/wiki/Infrasound
Indeed, this Wiki article gives reference to another article in English which says that Chelyabinsk meteorite produced the strongest infrasound wave since the bolide over Indonesia in 2009.
There is also this article in Russian: The song of Chelyabinsk meteorite. It says that this celestial body was named an "electrophonic bolide" because of the sounds produced by the electromagnetic discharge in the atmosphere. They say that this phenomenon is yet rather poorly studied. About 50 witnesses described a sound similar to the fireworks hissing several minutes before the explosion wave. The scientist from Ka Dar observatory, Stanislav Korotky, says that the sound waves cannot cover tens of thousands of kilometers distances within less than one second, which means that the nature of this sound was different. This phenomenon was actively studied by a Soviet scientist Vitaly Bronstain in 1982. By now, there are about a hundred scientific works on this subject, according to Harvard University.
I also found another article in Russian further describing the effects of Chelyabinsk meteorite on the ionosphere. It says that the bolide produced strong effects on the planet's ionosphere similar to the effects of geomagnetic storms. Such effects were registered 5.5 hours later in Yekaterinburg (Urals), 6 hours later in Rostov (South Russia) and 7 hours later in Moscow. The article describes these effects in detail. fwiw
