 Hearing Aid

A hearing aid is a small device that allows deaf individuals or people who are deaf or hard-of-hearing to listen better. Deaf or deaf and hard-of-hearing students usually use hearing aids most of the time. Hearing aids amplify sounds, so that they can hear teachers, friends, and what's around them better.

What is a Hearing Aid Used For?

  • Making Sounds Louder: The main purpose of a hearing aid is to increase sound so that students can hear things they would not be able to hear otherwise.

  • Listening in the Classroom: It allows students to better hear the instructions, lectures, and discussions of their instructors even if they cannot hear them.

  • Group Activities: In groups, the hearing aid allows students to hear others, hence making it easier for them to participate in discussions and activities.


  • Environmental Sounds: It may also allow the students to hear important environmental sounds, like the alarm or the bell, that may otherwise be unhearable.


How to Use a Hearing Aid:

  • Wearing the Device: The hearing aid is normally worn behind or inside the ear. It needs to be properly fitted so the microphone is facing in the correct direction for optimum quality of sound.


  • Turning It On: Many hearing aids have a straightforward on/off switch. Others are automatic and will switch on when inserted into the ear.


  • Adjusting the Volume: Some hearing aids permit users to adjust the volume to their desired level. For instance, when it is quiet, they may decrease the volume, and when the surroundings are noisy, they can increase it.


  • Use of Accessories: Most hearing aids are able to be connected to other devices like FM systems or microphones that help pick up sound from a teacher or speaker and send it straight into the hearing aid.


  • Charging: A few hearing aids have rechargeable batteries, and students need to charge them just one time during the night. Others use disposable batteries that must be replaced on a regular basis.


 Benefits:

  • Improved Hearing: Hearing aids make sounds louder so that students can hear speech, music, and surrounding sounds that they otherwise might not have heard.


  • Learning: Hearing aids allow students to stay more easily in step with classes, improving their ability to learn from the teacher and participate in class discussions.


  • Better Social Interactions: A hearing aid will enable students to talk to others and teachers with ease, be more able to make friends and participate in group activities, and


  • Safety: Hearing aids allow students to hear alarms, doorbells, and other sounds that could save them in an emergency.


  •  Convenient: Most hearing aids are discreet and small, hence convenient to wear all day without drawing attention.
Disadvantages:
  • Cost: Hearing aids are expensive, at times even in the range of thousands of dollars, and insurance won't always cover the entire cost.


  • Maintenance: Hearing aids need periodic maintenance. Batteries would need to be replaced and the machine cleaned in order to keep it working well.


  • Background Noise: In very loud settings, hearing aids will struggle to distinguish speech from background noise and will likely struggle even more to hear distinctly.


  • Not Applicable for Severe Hearing Impairment: Hearing aids are most effective for students with mild or moderate hearing impairment. For severe hearing impairment, a cochlear implant or other device might be needed.


  • Discomfort: Some students might find hearing aids uncomfortable, especially if they have to wear them for long periods of time or if the equipment is not fitting well.

How useful is it?

Hearing aids are extremely beneficial for deaf or hard-of-hearing pupils, especially mild to moderate hearing-impaired pupils. They allow the pupils to:


  • Listen more clearly in class: They can hear instructions, participate in discussions, and listen to explanations more easily.


  • Communicate socially: Pupils are able to communicate with others and participate in group activities, which makes them feel included and a part of the group.


  • Acquire language abilities: In young children, hearing aids facilitate the acquisition of language through an improvement in hearing whereby enhanced speech aids listening and understanding.


  • Improve learning process in general: Since students possess a better sense of hearing, they can understand lessons, learn, and participate in all aspects of learning.

Get to know me

My name is Kezang Wangmo Darjee, and I am 20 years old. I am currently pursuing my bachelor's degree in education at Paro college of Education, 2nd year. I completed my high school from Karma Academy in the year 2022.  I am currently enjoying my degree because this college is the place I prayed for, and for that I studied day and night, just hoping I get through the criteria and make my parents proud. My parents motivated me and encouraged me, even though I did not enjoy being at Karma Academy, I survived and a part of me feels thankful towards that school because I am here today because of Karma Academy. It laid the foundation for my future.  As a child, I really enjoyed being in the kitchen and trying out new recipes. and as an adult also, cooking and baking is still my hobby. I love to cook and bake for my families; it just makes me the happiest. even in the future, I just hope that my friends and families will enjoy having my food just as they do today. it keeps me moving ...

Summary.

It's interesting to consider these concepts of communicative, informative, and co-construction tools. As a student teacher, it's been greatly enlightening to consider how we've utilized these technologies. Considering WhatsApp, it's not simply an application for messaging, is it? That video call with my classmates, surrounded by our phones, trying to craft an explanation of a tricky idea – that's the picture that truly freezes a moment of collective learning. It wasn't so much discovering the answer; it was talking through it, listening to others' ideas, and having it confirmed. To this day, I value how much those informal discussions helped to build our knowledge and our bond as prospective teachers. It's simple to use, simple to access, and it's where the majority of our actual working together happened. And, there's our university VLE. It's slightly more structured, like our academic portal, I think. Scrolling through the lecture materials...

Reflection on Informative Tool

Image
  Informative Tool An information tool is something that gives us information we can use and enables us to learn more about a topic. It can be in various forms. For example, it could be a book explaining a topic, a website with facts, an app that educates you step by step, or even a video showing us how something works. Chapters, graphs, and diagrams are also instruments of information because they enable us to see and understand information better visually. Such instruments are made to inform, guide, or describe something in a more simple manner. Others utilize them in school, when they use it at work, or on a daily basis so that they may look for something or understand something better. Virtual Learning Environment (VLE) is our college website where we get access to lot of lecture notes and assignments and even information. How VLE is useful in our teaching and learning ? A Virtual Learning Environment (VLE) is an information device as it provides a virtual platform where lear...
