God’s Flawed Hearing System

Over at AiG, an old item has been pushed through their RSS feed and bumped onto my reader. It’s on how wonderful the human hearing system is.


I agree that the human ear is amazing.

The item, written by a Dr. Don DeYoung, includes some flat out incorrect assertions. It seems that lying isn’t really lying when it’s for The Kingdom.

Your eardrum is wonderfully designed to sense the tiniest changes in air pressure. But this has a potential downside. Loud, sustained noises could easily push the delicate parts of the inner ear beyond their safety limit, causing permanent damage.

By God’s wise design, however, something special happens under these conditions. God put a series of three tiny bones in your middle ear to pick up most vibrations. For their protection, He attached two tiny muscles to the first and last of these bones (the malleus and the stapes). At the instant these bones begin to vibrate beyond normal limits, the brain senses danger and sends a signal to tighten the muscles and momentarily shut down the ear’s sensitivity. This happens in a split second and is involuntary, a phenomenon called negative feedback.

The inner ear is thus protected from injury.

This system is so efficient at protecting the ear from injury that “Approximately 15 percent of Americans between the ages of 20 and 69 … have hearing loss that may have been caused by exposure to noise” (https://www.nidcd.nih.gov/health/noise-induced-hearing-loss)

It is reasonable to suggest that the all-wise Creator planned ahead to protect our ears from modern industry’s noisy environments

And yet the hearing loss page I linked to above goes on to say…
“However, long or repeated exposure to sounds at or above 85 decibels can cause hearing loss. The louder the sound, the shorter the amount of time it takes for NIHL to happen.”

For reference, 85 decibels is noisy city traffic, that’s quieter than a passing motorbike and music on a personal stereo.

AiG goes to confidently announce.

In contrast, evolution cannot explain how random mutations could possibly plan ahead for future needs.

It seems their god is as bad at planning ahead as AiG is at telling the truth.

But to cover their butts, the following is thrown in at the end.

Your ear must be prepared at all times to hear any intensity, from a mouse creeping behind your desk (nearly 0 decibels) to a jet engine (over 160 decibels). Your job is to take precautions or cover your ears. But God has given you help through the feedback mechanism.

Nothing like a good caveat in case some wretched internet anti-creationist comes along and reads their stuff. Is their faith really so week?

For a good starter on the evolution of the bones in the human ear from the reptilian ear and jaw bones, take a look at this page; https://ecomorph.wordpress.com/2014/05/07/can-you-hear-me-now-the-evolution-of-malleus-incus-and-stapes-in-early-hominins/
