三維列印頭盔與聽力保護裝置在防止龍蝦爆炸誘發聽力損傷之功能與組織學評估—以短尾矮袋鼠為模型

// Functional and histological assessment of 3D-printed helmet and hearing protection devices in preventing blast-induced auditory injury in Chinchillas

本研究評估3D列印頭盔及其搭配聽力保護裝置（HPDs）對連續高強度爆炸聲的聽覺保護效果｜有限元素分析優化頭盔設計，降低顱骨峰值應力47%｜雙重防護使聽覺腦幹反應閾值降低多達40分貝，並比單一或無防護更能保護毛細胞存活，展現更佳聽覺防護效益。

// This study evaluated a 3D-printed helmet's auditory protection alone and combined with hearing protection devices (HPDs) in chinchillas exposed to repeated high-intensity blasts. Finite element analysis optimized the helmet design, reducing peak skull stress by 47%. Dual protection significantly reduced auditory brainstem response threshold shifts by up to 40 dB and preserved hair cell survival better than single or no protection. Overall, combining the helmet and HPDs provided superior auditory protection against blast-induced injury.
