牛津和哥本哈根的科学家发现刺猬的听力可达85kHz，这有助于利用超声驱避剂保护它们免受车辆和割草机的侵害。 Oxford and Copenhagen scientists find hedgehogs hear up to 85kHz, aiding efforts to protect them from vehicles and lawnmowers using ultrasonic repellents.

牛津大学和哥本哈根大学的科学家发现，欧洲刺猬能够听到高达85kHz的声音，远超人类听觉，这得益于其独特的耳朵结构，类似于蝙蝠的回声定位。 Scientists at the University of Oxford and University of Copenhagen have found European hedgehogs can hear sounds up to 85kHz, far beyond human hearing, due to unique ear anatomy similar to echolocating bats. 这一基于脑干反应和微型CT扫描的发现，可能促成超声驱避剂的研发，以防止刺猬因车辆、割草机及其他危险而死亡。 The discovery, based on brainstem responses and micro-CT scans, could lead to ultrasonic repellents to prevent hedgehog deaths from vehicles, lawnmowers, and other dangers. 随着刺猬数量迅速减少，三分之一的刺猬在道路上死亡，研究人员致力于开发能够在不伤害人类或宠物的情况下威慑它们的装置。 With hedgehogs declining rapidly and one in three dying on roads, researchers aim to develop devices that deter them without harming humans or pets. 调查结果显示,刺绣猪可以使用超声波进行通信,为养护提供新的途径。 The findings suggest hedgehogs may use ultrasound for communication, offering new avenues for conservation.
