Abstract
The dependence of the escape time on the deviation from the critical point is investigated for the noisy on - off intermittency. The power-law scaling behaviour is destroyed by the noise in a wide region above the critical point. In the general case the width of the region decreases logarithmically with the decrease in the noise amplitude. Below the critical point the noise induced escape time is sensitive to the statistical properties of the chaotic driving signal. Universal exponential dependence holds only for the Gaussian approximation.
