The acoustic emission (AE) of short-lived static foams from non-ionic detergent Triton X-100 in ethanol-water solutions has been investigated. The AE of foam drainage process has shown two different stages of behaviour. The first step up to 80 s was without the appearance of AE signals. During this stage the rearrangement of bubbles has been observed. The next, main stage of drainage process proceeded with a high intensity AE generation. The results suggest that the AE technique gives the direct possibility of foam stability measurement.
