The Master Design of the Human Ear

When certain sidewinders say that various things around us have the "appearance" of design and imply that they are only the products of fish-to-fool evolution, they are not making scientific statements. The construction of the human ear is clearly engineered by the Master Builder.

Sound happens, disrupting the air with small cycles. When sound reaches the ear, resonance amplifies it in the canal and then things get serious. The brain makes it understandable (unless it's impossible), and we can hear someone calling, a symphony, alarms, water in a stream or ocean, and so much more. The entire process is amazingly complex, and we can defy someone who claims that it is the product of time, chance, random processes, and so on to say how the process and its specified complexity allegedly evolved.

Looking at the ear and how it works, it becomes immediately obvious that there is an awesome and very intricate process underlying our auditory sense. In fact, the human ear is one of the most intricate examples of miniature and sophisticated engineering on the planet.

My background is in mathematics applied to acoustic engineering, having performed research on the role of pressure waves with combustion. This includes very small variations in pressure, called acoustic waves, which travel through the air when we speak. Though small, they can even affect standing flames. That work involves the safety of jet engines which can under a certain phenomenon called ‘resonance’ (when one object vibrates in sympathy with another) amplify acoustic waves such that the vibrations grow and even destroy fan blades in the rotor. As we will see, resonance is an important property in hearing, and in particular in hearing the human voice.
