Plural of blaoner; multiple persons or things that make blaring sounds.
From blaoner + -s (standard English plural marker). This straightforward pluralization shows the normal morphological process for agent nouns.
The -s plural marker is so automatic in English that we rarely think about it, but it's actually a compression of Old English -as, and in Old English, different word categories took different plural markers depending on their gender—we've lost that complexity but kept the simple -s, which is why English is easier to learn as a second language than German or Russian.
