acoustic waves
akustinės bangos statusas T sritis Standartizacija ir metrologija apibrėžtis Tamprios medžiagos dalelių virpamojo judesio sklidimas. Pagal virpesių dažnį f akustinės bangos skirstomos į infragarsą (f mažiau nei 16 Hz), garsą (f nuo 16 Hz iki 20 · 10³ Hz; garso dažninės ribos subjektyvios), ultragarsą (f nuo 20 · 10³ Hz iki 10⁹ Hz), hipergarsą (f daugiau nei 10⁹ Hz). Akustinės bangos sklinda kietajame kūne, skystyje ir dujose, bet negali sklisti vakuume. atitikmenys: angl. acoustic waves vok. akustische Wellen, f rus. акустические волны, f pranc. ondes acoustiques, f
