A specific drophammer test apparatus for measuring the maximum absolute aco
ustic level was designed and installed. In this contribution we report the
results of the testing of six different explosives. All used substances, wh
ich are silver azide, lead azide, cyanuric triazide, 1,3,5-trinitro-2.4,6-t
riazidobenzene (TNTA), 1,1,3-dinitro-2,4,6-triazido-benzene (DNTA) and 1,3,
5-trinitro-2-monoazidobenzene (TNMA), contained at least one azide group.
