Your high school biology textbook may have given you the idea that modern science understands how hearing works. While science understands the general principles, researchers are still trying to understand the details.
Hearing starts with the skin and cartilage on the outside of our heads that we call the ear. This tissue is carefully designed to collect sound waves and focus them into the hole in the lower center part of the external ear. That hole is a tube that runs for about an inch to the eardrum. As the eardrum vibrates with the incoming sound, tiny specialized bones pick up the vibrations. One of these bones changes the vibrations into hydraulic pressure.
The sound, now converted to hydraulic pressure, is sent to the cochlea. This coiled, bony canal is lined with tissue that has four long rows of hair cells. A vibration as small as the width of an atom will move these hairs. Each movement of the hair causes a change in the electrical potential of the hair cell’s membrane. This change triggers a current that is fed to the auditory nerve and interpreted as sound by the brain. Each of the hairs in the ear responds best to a specific frequency.
The ability to hear could have been engineered using a much less complex design. Such a design, however, would leave us unable to hear the subtleties of an orchestra or a bird’s song. Our Creator is not only capable of excellent workmanship, but also generous in His creation.
2 Samuel 22:50
“Therefore I will give thanks unto thee, O LORD, among the heathen, and I will sing praises unto thy name.”
Prayer: I thank You, dear Father, for the richness of the sounds in Your creation. Let my voice praise You and tell others of Your wondrous works, especially the salvation You have prepared through the forgiveness of sins through Your Son, Jesus Christ. Amen.
