Studies conducted by the Naval Undersea Warfare Center (NUWC) and commercial environmental consultants (e.g., JASCO Applied Sciences) have consistently shown that deflagration reduces peak SPL by 20 to 40 dB compared to detonation of the same mass of high explosive.

Detonations produce a near-instantaneous rise time (< 1 microsecond in the near-field). Deflagrations produce rise times on the order of 5–50 milliseconds. This slower pressurisation reduces the potential for biological barotrauma (physical tissue damage from rapid pressure change). The pulse width (duration of the positive pressure phase) extends from ~1 ms (detonation) to 100–500 ms (deflagration), shifting energy from the impulsive regime to the continuous noise regime. Deflagrations produce rise times on the order of
