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. Importance of Hearing Protection If you’re around loud music a lot like I am, or if you are experiencing some hearing loss, I highly recommend getting a pair of hearing protection earplugs. 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.
5 Mind-Blowing Ways Your Senses Lie to You Every Day We are so completely dependent on our five senses every moment of the day that we totally forget how full of shit they can be. 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.
Eye:optics, anatomy and accommodation: Physclips - Light The photoreceptor cells in the human retina are classified, by their shape, into rods and cones. Cones, which are responsible for colour vision, come in three types, called red, green and blue according to whether they respond most strongly to long, medium and short wavelengths. (Page on this still to come.) Cones are concentrated in the fovea, the area directly behind the pupil, while rods are distributed over the whole retina. The photoreceptors are connected to retinal ganglion cells, which transmit electrical pulses called action potentials through the optic nerve to the brain. In this sketch, light arrives from the left, which means that light travels through the nerves on its way to the photo receptors.
