Article

Conditions under which a quasistatic approximation may be employed in the process of interaction of acoustic fields with vibration fields are considered. Criteria are found based on which the method error may be estimated in the case of a wideband range of a particular vibration field. The errors that arise in modulation of a reflected acoustic signal by phase and amplitude are estimated.

Keywords
