[28] and Paurobally and Pan [29] mentioned that the acoustic stiffness of the air cavity could be approximated by considering it as a hemicylindrical volume.
Knowing that the acoustic resonance of the air cavity is inversely proportional to the square root of the acoustic stiffness, it could be deduced that the small volume of the air cavity would result in a high-frequency acoustic resonance.
