“…Shock waves from collapsing cavitation bubbles have been the subject of interest to academics and industrialists due to their extraordinary potential of generating severe response dynamics in a variety of fields, ranging from biomedical sciences, nanomaterials, food processing, microelectronics, to liquid metal processing and additive manufacturing [1] , [2] , [3] , [4] , [5] , [6] . Also recently, fundamental studies investigated the spatial shock wave pressure in the cavitation centre and the threshold of shock waves upon solid–liquid impact respectively [7] , [8] further advancing the existing knowledge in the field. Hence, understanding the acoustically-induced cavitation shock waves, and specifically the detection and elucidation of acoustic signals (that can be used as a powerful tool to control cavitation activity during ultrasonic processing as in [9] , [10] ) emanated from bubble activity is vital for the development and further improvement of various applications and techniques allied to these fields.…”
