A few test measurements are presented which show in principal the feasibility of the sound determination using the velocity transfer coefficient.enFreifeldmessungKorkpolyurethanReflexionskoeffizientSchallgeschwindigkeitStahlplatteTransmissionskoeffizientWasserschallWasserschallmessungWerkstoffDetermination of the sound speed in materials by measurements at thin plate samples in free-field waterconference paper
