Observations and interpretation of modulation instability (MI) in an acoustic resonator with a crack-like defect are presented. This MI is similar in appearance to the conventionally disscussed MI, which arises due to the interplay between the reactive nonlinearity and velocity dispersion. However, the observed MI is due to an essentially different, purely dissipative, mechanism that can be common for waves of different physical nature. The mechanism exhibits interesting peculiarities, for example, the MI threshold can only be reached when the excitation frequency does not coincide with the resonator eigenfrequencies.
