The same standing wave mathematics applies to strings and acoustic systems

Evidence

Standing waves can also occur for any type of wave propagation. A transverse wave on a string, which is clamped at the ends, has standing waves that can be predicted using Equation 1.36, provided one uses the propagation velocity of the transverse wave for v. — David M.
