Does yelling cause avalanche?
Abstract: It remains a popular myth that avalanches can be triggered by noise. The pressure amplitudes caused by shouting or loud noise are at least about two orders of magnitude smaller (a few Pascal) than known efficient triggers. Triggering by sound can therefore be ruled out as a triggering option.
