Which distortion arises when acoustic metamaterial impedance functions mismatch?

A)Increased internal energy losses
B)Perfect acoustic transmission occurs
C)Decreased sound pressure level
D)Enhanced sound wave refraction

💡 Explanation

Increased energy losses occur because viscous and thermal dissipation becomes significant when there is impedance mismatch; therefore, sound waves attenuate rather than propagate efficiently, because impedance matching ensures optimal energy transfer.
