Introduction
People are used to using one’s eyes as their main source of sensing their surroundings, sometimes with their sense of smell as an auxiliary. However, sometimes it is not possible to use one’s vision effectively, for example, when one is trying to detect something at a significant distance, or when the conditions for viewing are not ideal, or perhaps when one has lost or has never possessed the sense of vision. All of these are situations where the sense of vision would be insufficient to meet one’s needs.
In order to over come these obstacles, humans discovered and alternate way to see the world using sound. Nevertheless, make no mistake; humans were far from the first to use this ‘advanced’ technology.
Echolocation
In 1793, Italian naturalist, Lazzaro Spallanzani found that blinded bats could navigate just as effectively as normal bats. After further research, it was discovered that bats navigate using echolocation, eventually, also known as biosonar. Echolocation is detection using sound waves. While different species of bats have evolved to using different ways of echolocation, the most precise of the species would be the Horseshoe bat. This unique bat generates an ultrasound frequency of 83 kHz using its larynx, and then listens and processes the echoes it hears. These echoes are made by the sound wave that the bat has generated bouncing off of objects in the range of the wave. The bat uses this information to interpret its surroundings.
Other birds and animals that use echolocation to some extent include, but are not limited to, dolphins, toothed whales, Oilbirds, Swiftlets, Shrews and Tenrecs.
It was not long before people realized what advantages this new discovery could mean.

In severe times such as the six miners missing by the Cave in at the Crandall Canyon coal mine in Utah, sound is an effective way to know the existence of the miners.
When we first began to watch this movie, I was excited to have the opportunity to learn more about Deaf life. It was nice that we were required to watch the movie, because while the movie had been suggested before I had almost forgotten it, even though I had wanted to see it. The film gave an introduction to life on planet “Eyeth,” but in doing
Eyes are the ‘organ of sight or vision; the visual sense; the sense of seeing’ (Biology-Online). The eye is an organ that detects light and sends signals along the optic nerve to the brain. The eye allows for light recognition and the ability to differentiate between colors, and light and dark. The eye is approximately 2.54 cm wide, 2.54 cm deep and 2.2 cm tall. The human eye has around 200-degree viewing angle and can see and detect more than 10 million colors and shades. This essay is going to look at ways of seeing. The possible problems with eyesight, and eyes of various kinds. It is one of the most rare problems today that is affecting people, all over the world. Around the world an estimate of 4 in 10 people have perfect vision/sight (BBC). The population of the world right now
Archaeology is a continuously evolving field where there is a constant stream of new branches and excavation methods. Due to the influx of new technologies and innovations in recent decades, archaeologists have been able to excavate previously inaccessible areas. For example, new diving equipment and tools such as proton magnetometers, side-scan sonar, sub-bottom profiler, and miniature submarines have allowed archaeologists to dive into the deep depths of the ocean. As a result, the branch of underwater archaeology was created to search for shipwrecks and other artifacts on the ocean floor. Underwater archaeology’s role has increased in recent years as it allows archaeologists to more accurately interpret the past by supplementing information gained through traditional land excavations.

Blindsight is often understood as supporting certain claims concerning the function and the status of the phenomenal qualities of visual perceptions. In this talk I am going to present a short argument to show that blindsight could not be understood as evidence for these claims. The reason is that blindsight cannot be adequately described as a special case of seeing. Consequently, it is not possible to draw inferences from it concerning the role of the phenomenal qualities for seeing.
In conclusion, our sensory perception is our only input to external worlds which we must attempt to thrive in successfully. Understanding that our five senses are critical to this, we must acknowledge misconceptions and untruths are frequently made. In a world of Photoshop and Reality TV which in essence is not real, it is our duty to ourselves to seek out the “truth” as best we can.
Perception, at most times, is a credible way to assess the world around us. Without perception, we would not know what to do with all the incoming information from our environment. Perception is constructed of our senses and the unconscious interpretations of those sensations. Our senses bring in information from our environment, and our brain interprets what those sensations mean. The five most commonly accepted senses -- taste, smell, hearing, sight, and touch -- all help create the world around us as we know it.
Visual Discrimination is “using the sense of sight to notice and compare the features of different items to distinguish one item from another” (NCLD Editorial Team, 2014) http://www.ncld.o...
When a sound is made a vibration is sent through the air. The vibrations are let off by the source, and this leads to something such as an ear to pick up the noise. Once the detector has picked up the wave, the wave must be ...
Visual perception plays a big part on how we perceive life. If we didn't have perception I don't know where we would be now.
Research Paper & nbsp;& nbsp;& nbsp;& nbsp;& nbsp;& nbs R Radar is usually taken for granted in these days of modern technology. Many people do not know how radar is really used, how it works, or why we need it. People are familiar with several uses of radar, like police enforcement radar guns and radar that measures how fast a baseball is pitched in a major league game. These are only a few of the many uses radar has to offer. Radar can determine several properties of an object from a distance, such as its position, speed, direction of travel, and shape; it can also detect objects out of the range of sight in all weather conditions, making it a fundamental utility for many industries.
An acoustic wave can simply be described as a longitudinal wave. A longitudinal wave is a wave that vibrates and moves in the direction of its propagation. This means the medium is either in the same or opposite direction of the way the wave travels. Acoustic waves are a form of Mechanical longitudinal waves; these waves are otherwise known as compression waves or compressional waves. Compressional waves obviously produce compression, decompression, and rarefaction to travel.
