在本文中，我们利用达穆瓦-以色列结条件在新牛顿理论下构造了声学薄壳虫洞（ATW）。为了通过应用剪切和粘贴方法确定 ATW 的稳定性，我们在获得模拟声学新牛顿解后立即找到了新牛顿流体动力学下 ATW 的表面密度和表面压力。我们通过使用不同类型的流体（例如线性正压流体 (LBF)、Chaplygin 流体 (CF)、对数流体 (LogF) 和多变流体 (PF)）进行稳定性分析，重点关注新牛顿参数的影响。我们表明，喉部需要具有负能量的流体来保持虫洞的稳定。如果选择合适的新牛顿参数 $\varsigma$、$A$ 和 $B$ 值，ATW 可以稳定。
In this paper, we constructed an acoustic thin-shell wormhole (ATW) under neo-Newtonian theory using the Darmois-Israel junction conditions. To determine the stability of the ATW by applying the cut-and-paste method, we found the surface density and surface pressure of the ATW under neo-Newtonian hydrodynamics just after obtaining an analog acoustic neo-Newtonian solution. We focused on the effects of the neo-Newtonian parameters by performing stability analyses using different types of fluids, such as a linear barotropic fluid (LBF), a Chaplygin fluid (CF), a logarithmic fluid (LogF), and a polytropic fluid (PF). We showed that a fluid with negative energy is required at the throat to keep the wormhole stable. The ATW can be stable if suitable values of the neo-Newtonian parameters $\varsigma$, $A$, and $B$ are chosen.
