Activate Your Mind! Cochrane Journal Club Hearing Test - Can You Hear This? We got a lot of positive feedback on our Can You Hear Like a Teenager? article, and it inspired us to take it just a little bit further. Check your hearing with a list of tones that go from 8Hz all the way up to 22,000Hz. It’s fairly common for people who are over 25 years of age to not be able to hear above 15kHz and also experience some level of hearing loss or hearing damage such as tinnitus. Musicians have a much higher risk of hearing loss that most people do, and many of us don’t really wear proper hearing protection. Take our online hearing test: listen to each of these tones and let us know where your hearing cuts out.

The Etymotic earlplugs don’t muffle the sound like conventional earplugs – they basically give you the same frequency response as without, but with a bit lower volume.

Your reality is cobbled together from a bunch of different parts of your brain working in conjunction, and often it's like a bickering conference room full of uncooperative co-workers. In fact, we're pretty sure the thing your brain does best is convince you that it works. But it doesn't take much to spot the bizarre little flaws in your gray matter. #5. Photos.com/AbleStock.com/Getty Images When you hear someone talk, the whole process is pretty straightforward, right? Short answer: your eyes. In the clip, you see (and hear) a guy saying "bah bah bah" over and over. BBCYour brain also gave the "fah" version a tan, for unknown reasons. This illusion is called the McGurk effect, and the creepiest part is that, even knowing know full well what's going on, you can't get your ears to hear the correct sound. But that's not the only time your eyes screw you over ... #4.
