ABSTRACT: Although concussion mortars have been used for many years at band concerts and in theatrical performances, there has been relatively little investigation of the effectiveness of their basic design. Measurements of the effect of two modifications of the design of concussion mortars indicate that significant improvements in their performance were achieved; however, only for light powder loads. Though somewhat disappointing, these designs may be of use in situations where increased loudness of report is needed without an increase in smoke production. Measurements were also made of the effect of loading materials (whether inert, a fuel, or an oxidizer) on top of a commonly used concussion powder. It was found that all of these produced increased sound output. However, this seemed to be mostly the result of added confinement of the concussion powder.
