Abstract: In spite of recent studies of subaudible acoustic emissions, there has been relatively little work done in the soil mechanics area. This technical note presents a technique of monitoring acoustic emissions of soil under stress. Utilization of such a technique seems to provide an alternate to measuring soil strains, which in the in situ state is quite difficult. The technique may offer a nondestructive testing method for the monitoring of a wide variety of soils under stress.
