Limitations to the sight and hearing
There are some limitations to the senses of sight and sense of hearing. For example, our eyes cannot see very small objects such as germs while our ears could not hear very small or very strong. However, with the advent of modern technology, obstacles and limitations to the senses as this can also be overcome. To overcome the limitations of sight, the telescope, microscope and magnifier are used. The telescope let the space scientists to be able to look very distant objects like the moon, so that we know more about space. The function of the microscope is to view very small objects such as microorganisms. It is very useful to the microbiologists. Besides that, the magnifier also can overcome the limitations of sight because it can magnify the small objects. Tools to overcome the limitations of the senses of hearing we used are microphone. It can convert acoustic waves into mechanical vibrations so that the sound is amplified and we can hear clearly. The stethoscope is useful to the doctors because they can hear the sound of heartbeats by this tool. The loudspeaker is used by the teachers to make announcements during the assemblies in the school. In conclusion, advances of technology help us to overcome the limitation of sight and hearing.

    Summary Of Chapter 11 Hearing

    While reading Chapter 11, “Hearing”, I learned some pretty interesting things. Our ability to hear events that we can’t see serves an important signaling function for both animals and humans. For an animal living in the forest, the rustle of leaves or the snap of a twig may signal the approach of a predator. For humans, hearing provides signals such as the warning sound of a smoke alarm or an ambulance siren, the distinctive high indicate problems in a car engine. Hearing not only informs us about things that are happening that we can’t see, but perhaps most important of all, it adds richness to our lives through music and facilitates communication by means of speech.…

By reaching out to old people, the author touched her audience by describing who she was talking to and what solutions there were for them.…

    Without telescopes, our view of the universe is quite small and limited to what our human eyes can show us. Having the ability to see further into space can give us a greater perspective as to our place in the universe and what else is out there. There are many telescopes used to improve our knowledge of the universe but one of the greatest would be the Hubble Space Telescope.…

    Compare And Contrast Essay On Human Senses

    Describing sound and sight to a person who could not experience either is very challenging. Many people who can experience both, take for granted their abilities and do not think about the possibility of not being able to see or hear. In order to describe sound and sight to a person who cannot experience either, it must contain descriptive words that use the three other basic human senses. Also, describing the three other senses while using literary devices, such as similes. One everyday event a person can experience is walking through the park. Walking through the park has many exciting endeavors; there are children playing, the wonderful smell of food, and the pleasant sights.…

    Echolocation

    Vision and hearing are closely related in that they can process reflected waves of energy. Vision processes light waves as they travel from their source, bounce off surfaces throughout the environment and enter the eyes. Similarly, the auditory system processes sound waves as they travel from their source, bounce off surfaces and enter the ears. Both systems can extract a great deal of information about the environment by interpreting the complex patterns of reflected energy that they receive. In the case of sound, these waves of reflected energy are called "echoes".…

    Waves, Sound and Light

    Its weird how some people don’t question the things that are obvious to us. The things we see, how do we see it? What makes it visible to us? Is it only because we have eyes, or is there another factor. The great Aristotle explained it by having something in our eyes that emits “something” to an object and that’s why things are visible to us. Another question we could ask from our daily life is that how come we can hear? What is it that we hear? Why do we hear it and deaf people don’t? How do we receive any sound? People use sound all the time. We rely on sounds to communicate. Unexpected noises may warn us of danger. The sounds we hear tell us a lot about our surroundings. Many animals also use sound. Even animals that live in water. Since only the very top of the ocean receives light from the sun, animals have difficulty using their eyes to find their way around in deeper waters. Once animals dive, they rely heavily on their hearing to sense their environment. In this essay I’m going to answer these questions by explaining in turn what light and sound are, but first we need to know what waves are in order to make it easy to understand the others.…

    Hubble Telescope

    A ground breaking new tool used to study the heavens was introduced in the 17th century. This tool was known as the telescope. It revealed the cosmos in a different way than our naked eye could ever perceive. The telescope opened doors to countless stars, nebulae, galaxies, and a slew of never before seen wonders. With its creation came limitations and caused the need to improve and upgrade the methods in which the telescope functioned and find new ways of viewing the heavens.There are three main types of telescopes; refractor telescope, reflector telescope and compound telescope, also known as catadioptric telescopes. Each of these telescopes has a main function which is its ability to gather light. The telescope also has resolving power, which allows the telescope to reveal details in objects and a magnifying power, which scales the object in size through the telescope. Every telescope has these functions,…

    Hearing is an extraordinary phenomenon. It allows us to experience the joy of music, the sounds of nature and is fundamental for communication - yet is often taken for granted.

Tasks and interactions that were once so simple became strenuous without the aid of adequate hearing.…

    Personal Narrative: My Experience With Hearing Aids

    It was the fall of the year 2000, when I was six years old, my family gathered together one day for an important meeting — they had discovered my hearing loss, and this predicament paved the way for the communication struggles and frustration that I will face, but also opens a door to good friendship, love and support that I will receive. I am currently diagnosed with severe sensorineural hearing loss on both ears and is wearing bilateral hearing aids. Although I have many interests, hobbies, educational achievement, I feel my hearing impairment is a key component that defined me. My hearing aids improved my hearing but was not a cure. A deaf person David Peter said, “technology makes life so easy, and advances at such a breakneck clip, that sometimes we forget that all the tech in the world still can't change the way some people experience the world” (Peter, David). This phrase cannot be more accurate as there are many things I cannot…
