Sound travels in two ways, one we hear and one we don't. We can see the visible part of a wave when it hits our eyes, but sound can also travel through other parts of your body as well. Sound travels through the air in waves, which is why we can see them when you blow into a bottle or make ocean surf sounds with your mouth. It also travels through bones in waves! If you've ever hit your funny bone on something hard enough to make a sound, then you've experienced this firsthand!

Sound also travels through the skull – even though it's not actually your head that makes noise when you clap your hands together (the bones in between them do). And finally, sound can travel through brain matter – which might be why old people tend to look like they're listening more intently than people who are younger!

Bone conduction is the ability of sound waves to travel through bones in your body, which can then be used to create headphones and speakers. We'll discuss how the technology works, how it can be used, and what the benefits are.

Bone conduction works best when there are loud noises all around you, like during a concert or while riding on an airplane. Bone conduction allows you to hear people talking even if they aren't directly in front of you—this is especially helpful if there's a lot of background noise! This makes them ideal for situations where someone might not be able to hear them over their own voice or other sounds.

The good news is that bone conduction technology is not for everyone. If you have a hearing impairment, bone conduction may not work for you. It’s also recommended not to use bone conduction if you are under the age of 12 or have had ear surgery in the past 6 months.

If you are unsure if bone conduction will work for your situation, talk with your doctor before trying it out!
