Timothy Leighton是英国南安普敦大学声与振动研究所的教授，研究方向为超声波及水下声学。他是英国皇家学会，皇家工程学院和医学科学院三个国家研究院的院士。他1985年毕业于英国剑桥大学，获得双文学硕士学位（物理与理论物理），并于1988年在同所大学修得博士学位。已获国际奖8项，发明奖6项。2006年帕特森奖章给他的颁奖词是：“Timothy Leighton在多个领域内都作出巨大贡献，是目前世界上四个领域内公认的带头人”。在2017年，皇家学会宣布授予他皇家学会克利福德帕特森奖章，并称赞“他做了许多声学基础研究并可应用在许多领域，包括抗菌药物耐药性，地雷探测，胎儿检测，救灾，气候变化和海洋生物”。他主持了一个研究小组，是NAMRIP（抗菌药物耐药性和感染预防网络）的创始主席和HEFUA（空气中超声健康效应组织）的创始主席。他也是许多政府和国际机构的顾问。
报告摘要：
Exploration of the planets in our solar system, and further afield, requires expertise from many disciplines. Understanding of the need to include the knowledge and skills of the underwater acoustician into planetary exploration is only just developing.
We have sent many probes to the planets and moons of our solar system, which have delivered a vast library of images that allow us to perceive what other worlds look like – but we have never heard the sound of another world. Similarly, we have sent some acoustical instrumentation to other worlds (for example to measure the speed of sound in an atmosphere and infer its chemical properties), but assumptions that it will behave as it does on Earth need to be validated.
In many ways, understanding of acoustical characteristics of the thick atmosphere of Venus (with a density at ground level that is 6.5% that of water) requires the knowledge of an underwater acoustician as much as a researcher who studies Earth’s atmosphere. And when we discuss probes to study the under-ice oceans of the moons of Jupiter, an underwater acoustician is definitely called for. This lecture explores these topics.
