Äänekoski is named after the nearby rapids. Folk etymology connects the name to the wordääni "sound", but Terho Itkonen has suggested another origin: aSámi term meaning "big, large" (compareNorthern Sámieanas, "most").
Swedish sources mention a salmon fishery by the rapids around 1455,Ænækoski laxefiskeri. At the time, it was not a proper settlement and was located in the hunting grounds of the people ofSysmä. TheRautalampi parish was established in 1561, at the time it was a large parish covering most of Central Finland north of thePäijänne. TheLaukaa parish, including the area of Äänekoski, was separated from Rautalampi in 1628.
A settlement named Äänekoski has existed at least since 1752. It remained a part of Laukaa until the parish was established in 1907 and the municipalityÄänekosken maalaiskunta was established in 1911. At the time, Äänekosken maalaiskunta was called simplyÄänekoski. The municipality was divided in 1932: the actual settlement of Äänekoski became thekauppala of Äänekoski,Suolahti became anotherkauppala while the old Äänekoski municipality was renamedÄänekosken maalaiskunta and its administrative seat was moved to the village of Honkola. Äänekoski and Äänekosken maalaiskunta still shared a parish.[7]
