Research into novel initiation systems (e.g., laser-induced plasma deflagration or chemical foam injection) aims to slow the burn rate further, pushing acoustic energy entirely into the infrasonic band (< 10 Hz), where it becomes indistinguishable from natural seismic noise. Acoustic characterisation of these prototype systems is the frontier of marine UXO disposal.
While a single deflagration has a lower peak SPL than a detonation, disposal campaigns may involve multiple deflagrations over a day. The Sound Exposure Level (SEL), which integrates total acoustic energy over time, becomes the relevant metric. For a single event, the SEL of a deflagration is typically 15–25 dB lower than a detonation. However, because deflagration lasts longer, its average SEL per second is much lower, meaning that multiple deflagrations can be conducted with less cumulative impact than a single large detonation.
A donor charge is used to trigger a supersonic shock wave that travels through the UXO's main explosive filler. This causes the entire mass to react almost simultaneously, resulting in a massive, instantaneous release of energy, gas, and sound.
Here are a few options for a post on "Underwater Acoustic Characterisation of Unexploded Ordnance (UXO) Disposal Using Deflagration," ranging from professional to technical styles. Option 1: Professional (LinkedIn Style)
The data is unequivocal: deflagration reduces peak sound pressure levels by 20–40 dB, eliminates shock-induced barotrauma risk, and shrinks injury zones by an order of magnitude. However, the low-frequency propagation of deflagration energy requires careful assessment of chronic behavioral disruption in mysticetes.
