The Physiology and Acoustics of the Human Voice - Andy McIntosh

Описание: The way the human voice works is a marvel of acoustic engineering, and each person’s voice is a unique outworking of this engineering. In this session, we will discuss the anatomy and physiology of the human throat and larynx. The shape of our vocal tract adds many harmonics to the sound we make. How have humans been designed to make sounds and further to combine words and music to sing, and what does this design tell us about the One whose voice spoke us into existence? We consider how the uniqueness of the human voice points us to Christ, whose voice is supremely unique above all others. He who spoke and controlled the wind and waves will one day raise all from the graves (John 5:28, 29) with His voice.

Andy McIntosh holds an Emeritus chair in Thermodynamics at the University of Leeds and is also an adjunct professor of Engineering at Liberty University in Virginia. He has had a long scientific research career concerning mathematics, combustion and aeronautics, both in academia and in a government establishment, and is author of over 200 academic papers. Andy has long worked on combustion and its interaction with acoustics and larger pressure waves. He has also worked on the mathematical modelling of ignition, and he is the inventor of the 𝜇Mist novel spray technology which mimics the Bombardier beetle spray and has led to this spray technology being applied to fuel injectors, pharmaceutical sprays, aerosols and more recently fire sprinkler systems. This was awarded the 2010 Times Higher Educational award for the Outstanding Contribution to Innovation and Technology. His work has also included investigations into the fundamental link between thermodynamics and information. This strikes at the heart of the issue concerning abiogenesis – the information in living systems is neither matter nor energy but is absolutely essential for life.

Andy now lectures widely on origins, and has authored the books “Genesis for Today” (Day One, 6th Edition, 2017), and “A verse by verse examination of Genesis 1-11” (Day One, 2016) and has contributed to a number of other books including “Wonders of Creation – Design in a fallen world”(co-authored with Stuart Burgess and Brian Edwards, Day One, 2017), “Origins – examining the evidence” (Truth in Science, 2011), “In six days” (Master Books, 2009) and “Should Christians embrace Evolution?” (IVP, 2009). He has also written the booklet “Are you really an Atheist?” (2018) and co-authored the booklets “Is it True – Evidence for Creation” (2018) and “A wonder of Creation – the Kingfisher” (2024) and is co-director of the UK education think tank Truth in Science. He is married with 4 children (one of whom died in infancy), and 7 grandchildren.
