The term 'low explosive' is used for explosives that are actually
mixtures of combustible materials with an oxidizer. They generally
just deflagrate unless confined, with some having flame fronts
approaching the speed of sound (90+%).

I wonder what value of the 'speed of sound' is used in this description?
Is it the speed of sound in air at 1 ATM, or is
it the speed of sound in the gases in the interstitial volume
of the explosive granules? Certainly the speed of sound in the
latter will rise quickly as the internal pressure rises.

The term 'high explosive' is used for explosives that typically have
detonation fronts well above the speed of sound (an order of magnitude
faster or more). They will be divided into three categories based on
their sensitivity to shock.

Does the 'speed of sound' here mean the speed of sound in the solid
material?
