•Emission angles of sources affect the accuracy of solid velocity measurement.•Deviation of incidence from critical angles reduces wave amplitude and frequency.•Adjusting offsets or incidence help P wave velocity extraction of slow solids.•Using S-wave first jump can avoid the interference of the le...
