Why Do You Hate the Sound of Your Own Voice?

Reader Christah wrote to ask, “Why do our voices sound different to us than they do to other people/on recordings?” And Jenny asked on Facebook, "Why do we hate the sound of our own voice?"

For many of us, there are few things more painful than hearing a recording of our own voices. They don’t sound like we think they should. They’re tinnier, higher and just not right. The tape (or mp3) doesn’t lie, though, and the way we think we sound isn’t how we really sound to everyone else. This is a cruel trick that happens because of the ways that sounds can travel to our inner ear.

Every sound we hear—birds chirping, bees buzzing, people talking, and recordings—is a wave of pressure moving through the air. Our outer ears “catch” these waves and funnel them into our head through the ear canal. They strike the ear drum, which starts vibrating, and those vibrations travel to the inner ear, where they’re translated into signals that can be sent via the auditory nerve to the brain for interpretation.

Good Vibrations

The inner ear doesn’t get stimulated only by external sound waves coming down the ear canal, though. It also picks up on vibrations happening inside the body, and it's a combination of these two things that makes up the sound you hear when you talk.

When you speak, vibrations from your vocal cords resonate in your throat and mouth, and some get transmitted and conducted by the bones in your neck and head. The inner ear responds to these just like any other vibrations, turning them into electrical signals and sending them to the brain. Whenever you speak, your inner ear is stimulated both by internal vibrations in your bones and by the sound coming out of your mouth and traveling through the air and into the ears.

This combination of vibrations coming to the inner ear by two different paths gives your voice (as you normally hear it) a unique character that other, “air only” sounds don’t have. In particular, your bones enhance deeper, lower-frequency vibrations and give your voice a fuller, bassier quality that’s lacking when you hear it on a recording.

Big Questions
What's the Difference Between Gophers and Groundhogs?

Gophers and groundhogs. Groundhogs and gophers. They're both deceptively cuddly woodland rodents that scurry through underground tunnels and chow down on plants. But whether you're a nature nerd, a Golden Gophers football fan, or planning a pre-spring trip to Punxsutawney, Pennsylvania, you might want to know the difference between groundhogs and gophers.

Despite their similar appearances and burrowing habits, groundhogs and gophers don't have a whole lot in common—they don't even belong to the same family. For example, gophers belong to the family Geomyidae, a group that includes pocket gophers (sometimes referred to as "true" gophers), kangaroo rats, and pocket mice.

Groundhogs, meanwhile, are members of the Sciuridae (meaning shadow-tail) family and belong to the genus Marmota. Marmots are diurnal ground squirrels, Daniel Blumstein, a UCLA biologist and marmot expert, tells Mental Floss. "There are 15 species of marmot, and groundhogs are one of them," he explains.

Science aside, there are plenty of other visible differences between the two animals. Gophers, for example, have hairless tails, protruding yellow or brownish teeth, and fur-lined cheek pockets for storing food—all traits that make them different from groundhogs. The feet of gophers are often pink, while groundhogs have brown or black feet. And while the tiny gopher tends to weigh around two or so pounds, groundhogs can grow to around 13 pounds.

While both types of rodent eat mostly vegetation, gophers prefer roots and tubers (much to the dismay of gardeners trying to plant new specimens), while groundhogs like vegetation and fruits. This means that the former animals rarely emerge from their burrows, while the latter are more commonly seen out and about.

Groundhogs "have burrows underground they use for safety, and they hibernate in their burrows," Blumstein says. "They're active during the day above ground, eating a variety of plants and running back to their burrows to safety. If it's too hot, they'll go back into their burrow. If the weather gets crappy, they'll go back into their burrow during the day as well."

But that doesn't necessarily mean that gophers are the more reclusive of the two, as groundhogs famously hibernate during the winter. Gophers, on the other hand, remain active—and wreck lawns—year-round.

"What's really interesting is if you go to a place where there's gophers, in the spring, what you'll see are what is called eskers," or winding mounds of soil, Blumstein says [PDF]. "Basically, they dig all winter long through the earth, but then they tunnel through snow, and they leave dirt in these snow tunnels."

If all this rodent talk has you now thinking about woodchucks and other woodland creatures, know that groundhogs have plenty of nicknames, including "whistle-pig" and "woodchuck," while the only nicknames for gophers appear to be bitter monikers coined by Wisconsin Badgers fans.

Big Questions
Why Does Santa Claus Give Coal to Bad Kids?

The tradition of giving misbehaving children lumps of fossil fuel predates the Santa we know, and is also associated with St. Nicholas, Sinterklaas, and Italy’s La Befana. Though there doesn't seem to be one specific legend or history about any of these figures that gives a concrete reason for doling out coal specifically, the common thread between all of them seems to be convenience.

Santa and La Befana both get into people’s homes via the fireplace chimney and leave gifts in stockings hung from the mantel. Sinterklaas’s controversial assistant, Black Pete, also comes down the chimney and places gifts in shoes left out near the fireplace. St. Nick used to come in the window, and then switched to the chimney when they became common in Europe. Like Sinterklaas, his presents are traditionally slipped into shoes sitting by the fire.

So, let’s step into the speculation zone: All of these characters are tied to the fireplace. When filling the stockings or the shoes, the holiday gift givers sometimes run into a kid who doesn’t deserve a present. So to send a message and encourage better behavior next year, they leave something less desirable than the usual toys, money, or candy—and the fireplace would seem to make an easy and obvious source of non-presents. All the individual would need to do is reach down into the fireplace and grab a lump of coal. (While many people think of fireplaces burning wood logs, coal-fired ones were very common during the 19th and early 20th centuries, which is when the American Santa mythos was being established.)

That said, with the exception of Santa, none of these characters limits himself to coal when it comes to bad kids. They’ve also been said to leave bundles of twigs, bags of salt, garlic, and onions, which suggests that they’re less reluctant than Santa to haul their bad kid gifts around all night in addition to the good presents.
