Plot index acoustic waves
WebbExternal sound radiation by a cylinder has no acoustic–structural coupling constraints other than the requirement that the acoustic wavenumber (k = ω / c) must be greater than the structural wave-number, for effective radiation. There are three relevant structural wave numbers . Cylinder modes are classified into two groups: 1.
