了解听觉机制和声音传导

人耳是最先进的声音和振动放大系统之一。德国Polytec激光测振仪,是目前世界上最先进的振动测量系统,具有易于操作和极高精度的优点,用于确定振动特性和动态性能,它们为研究者们了解听力工作原理提供了完全新的可能性。通过使用具有极高灵敏度的非接触式激光测振仪,科学家们不仅可检测中耳内从鼓膜到镫骨底板的声传导,还包括在内耳耳蜗中的机电信号转导细节。 

通过鼓膜的振动特性可直接深入了解因听骨链的镫骨固定或硬化变化所导致听力损失的原因。在医学研究中,使用激光测振仪进行的激光声抗导测试,能让听力学家快速获得鼓膜的频率响应。

HLV Hearing Laser Vibrometer for optical measurement in otology

The human ear is one of the most sophisticated sound and vibration amplification systems. And special measuerement tasks require application-specific instrumentation. For use in ear mechanics and otological research, use the HLV Hearing Laser Vibrometer. See the HLV datasheet for further specification.

Laser vibrometers are also indispensable for the development, inspection, calibration and certification of middle ear implants. In research, laser vibrometers are used during operations to check that middle ear implants and prostheses (TORP, PORP) are securely connected. They therefore help to ensure that operations are successful and to document the same in an audit-proof way.
