A hearing aid is an instrument designed to aid a person's hearing ability. Hearing aids are designed to help an individual's ability to easily hear sounds from his environment. Hearing aids has been used by patients suffering from hearing disorders for several decades and advancement in technology has been improving its design. Technological advancement in wireless, metal and sound technology will have an immensely great effect on the development of hearing aids. The following are examples of technological improvements that may occur in the development of hearing aids in the next few years. There is a challenge of recharging hearing aids for several hours or sometimes overnight which might disrupt its usage and functions. Although, some hearing aids have the ability to work for several hours or days but there is always the need to recharge it often.
A Lithium-ion rechargeable battery cannot fit perfectly into the ear canal because of its size and it also produces much heat which leads to a smaller battery life. This results in the design of external hearing aids using the benefits of more available space for the development of a more effective device. Graphene is an element that can be adopted in the design of latest hearing aids. It is an element with physical and electromagnetic properties that makes it suitable for use at room temperature. The incorporation of this element would produce a good hearing aid with long lasting ability. Coupled with this ability is the fact that the battery of the hearing aid would be small and time taken to recharge will be very minimal. More innovations would be made with the use of graphene in the development of durable and long lasting hearing aids.
More gadgets can be added to the design of hearing aids as the battery efficiency and effectiveness of the device is improved. The addition of Bluetooth wireless will enable easy communication and transferring of sounds and informations with external equipments. It can be used as an interconnection between the user and external gadgets. Hearing aids can be designed to interact and communicate with external devices like cameras, theatre speakers and so on. Many organisations and corporations use this simple technology to transform sunlight to electrical energy. Likewise, IBM inventors are designing a source of energy that can be naturally replenished based on human motion using the exact technology used to transform light energy to other forms of energy. Therefore, green energy technology is free for all.
Interconnection of hearing aids with smartphones will be of great connection advantage to the user. This improvement in hearing aid technology would provide several benefits useful for helping people with hearing disorders. An advantage of green energy technology is that once a client pays for an equipment, e.g. windmill or solar panels, to power an environment, they do not have to pay continuously for it. The automobile industry has also employed the green energy technology in the production of vehicles. Another example of renewable green energy. They would also help users to listen and hear phone conversations clearly without any difficulty. They could also be used as a notifier and reminder by sending audio notifications through them. This would be of good help to patients and users who do not want to miss any dose of medication.
Green energy is a form of energy derived from natural sources like sunlight, wind, rain, tides, plants, algae and geothermal heat. The energy derived from these sources can be renewed. This means that they can be naturally restored without hurting the ozone layer. Sources of green energy are abundant everywhere in the world in urban, rural and even remote areas without electric power. Examples of green energy are solar power, wind power, hydro power, geothermal energy, biomass and biofuels.
Recent improvements in green energy technology has reduced the price of solar panel for solar energy, wind turbines for wind power and other green energy instruments. These sources of energy are readily available and accessible to everyone, anywhere and at any time than other sources of electrical energy like oil, gas, coal, diesel etc.
Green energy technology is useful in place of fossil fuels for purposes such as provision of electricity, automobile fuel, space fuel, transportation, water etc. The invention of solar power has been very useful as many people now erect solar panels in their houses eliminating the need to pay for electricity bills.
