Near field acoustical signals from fireballs (ranges $<$ 200 km), when detected by dense ground networks, may be used to estimate the orientation of the trajectory of a fireball (Pujol et al., 2005) as well as fragmentation locations (Kalenda et al., 2014; Edwards and Hildebrand, 2004). Distinguishing ballistic arrivals (from the cylindrical shock of the fireball) from fragmentation generated signals (quasi-spherical sources) remains a challenge, but are obtainable through analysis of the acoustic path and the timing observed at ground instruments. Here we describe an integrated computer code, termed the Bolide Acoustic Modelling program or BAM, to estimate fireball trajectories and energetics. We develop a new methodology for measuring energy release from bolide fragmentation episodes solely from acoustic measurements and incorporate this into BAM. We also explore the sensitivity of seismo-acoustic fireball solutions and energy estimates to uncertainty in the underlying atmospheric model. Applying BAM to the Stubenberg meteorite producing fireball, we find the total fireball energy from ballistic arrivals to be approximately $5\times {10}^{10}$ J which compares favorably to the optical estimate of $4.36\times {10}^{10}$ J. The combined fragmentation energy of the Stubenberg event from acoustic data was found to be ${1.47}_{-0.12}^{+0.28}\times {10}^{10}$ J, roughly one third of the ballistic or optical total energy. We also show that measuring fireball velocities from acoustic data alone is very challenging but may be possible for slow, deeply penetrating fireballs with shallow entry angles occurring over dense seismic/infrasound networks.

火球的近场声信号（范围 $<$200 km），当被密集的地面网络检测到时，可用于估算火球轨迹的方向（Pujol等，2005）以及碎片位置（Kalenda等，2014； Edwards和Hildebrand，2004） ）。区分弹道到达（来自火球的圆柱形冲击）与碎片产生的信号（准球形源）仍然是一个挑战，但是可以通过分析声波路径和在地面仪器上观察到的时间来获得。在这里，我们描述了一个集成的计算机代码，称为Bolide声学建模程序或BAM，用于估计火球的轨迹和能量。我们开发了一种新的方法，用于仅通过声学测量来测量硼化物碎片发作中的能量释放，并将其整合到BAM中。我们还探讨了地震声火球解决方案和能量估计对潜在大气模型不确定性的敏感性。将BAM应用于产生Stubenberg陨石的火球，我们发现弹道到达的总火球能量约为$5\times {10}^{10}$ 与光学估计相比有利的J $4.36\times {10}^{10}$ J.从声学数据得出的Stubenberg事件的合并碎片能为 ${1.47}_{-0.12}^{+0.28}\times {10}^{10}$J，大约是弹道或光学总能量的三分之一。我们还表明，仅通过声学数据来测量火球速度是非常具有挑战性的，但对于在密集的地震/次声网络上发生的，具有浅入射角的缓慢，深度穿透的火球来说，这可能是可行的。
