Top 10 Incredible Sound Illusions

Top 10 Incredible Sound Illusions
Weird Stuff Following the popularity of our optical illusions lists (20 Amazing Optical Illusions, and Another 10 Amazing Optical Illusions), we have put together an amazing array of sound illusions (auditory illusions). In these illusions, your mind is tricked in to thinking it is hearing something when, in fact, it is not. To get the most out of this list you should have a set of stereo headphones and a stereo sound system. Unless otherwise noted (before each audio file), you should listen to these sounds with your stereo. Laptop speakers are not suitable for most of these illusions. This illusion was discovered by Diana Deutsch, and is an example of our brains “grouping” similar notes together. There are several ways in which people perceive these sounds, but the most common is to group the high and low notes together. NOTE: Listen through stereo headphones, or stereo separated loudspeakers, best placed some distance apart. Shepherds Ascending Tones This recording is subtle. Wait! Bonus Related:  Illusions

Audio "Optical" Illusions This time “Mighty Optical Illusions” brings you another type of illusion. Audio illusions, also known as Audio Paradoxes are sometimes to be found in nature. The best known audio paradox is known as Shepard’s paradox. It is the audio equivalent of the endless staircase illusion made famous by M. C. Escher. The following graph of Shepard’s paradox shows frequency versus time. It may be obvious to the eye, but the ear cannot perceive where the sample starts and finishes. Shepard’s ascending tones (MP3) – This is a recording of Shepard’s paradox synthesized by Jean-Claude Risset. Falling bells (MP3) – This is a recording of a paradox where bells sound as if they are falling through space. Quickening Beat (MP3) – This recording is subtle.

Animal Sleep Most animals have a daily pattern of rest and activity. Some animals are more active during the day (diurnal) and some are more active during the night (nocturnal). How much time do animals spend sleeping? Well, it depends on the animal: References: This table was adapted from four sources: Aserinsky, E., Eyelid condition at birth: relationship to adult mammalian sleep-waking patterns, In Rapid Eye Movement Sleep, edited by B.N.

psychtalkradio Auditory Illusions: A Tour of Tricky Sounds Auditory illusions are sounds that trick us. We all mishear things at times, but well-crafted illusions are persistently deceptive. On this podcast, we string together some great illusions. As you will hear, they reveal aspects of our brains’ workings that are usually invisible. In trawling the net, we came across many sound illusion lists. In the podcast we mention the falling bells illusion, which makes more sense with the image below. One of the best sound illusions requires video. In the podcast, we promise a video of an undersea creature. If you watched the video to the end, you heard that the octopus is not perfectly matched to its surroundings; it is just similar enough that our brain does not detect it. The brain has to interpret complicated and ambiguous data from our senses, and because of evolution it usually does a good job simulating the world. Download the podcast here.
