Hearing Aids – Styles and Features
Complex and custom-made digital electroacoustic devices that can be computer-programmed to enhance sounds at certain frequencies are modern hearing aids. In the last fifty years, while the technology used in automated hearing aids has increased significantly, all hearing instruments maintain the same basic functions and components.Learn more about us at Grand Rapids Hearing Aids
Basic features for hearing aids:
Via the microphone, sound waves penetrate all hearing aids, turning acoustic signals into electrical signals or pulses. The amplifier then increases the electric signal intensity and cleans up any noise that it senses. Then this electrical signal is transformed back into an acoustic signal so that it can be heard by the consumer. After that the receiver directs the sound into the ear canal. For these conversion processes, a battery supplies the necessary power. There are also many features and controls for many digital hearing aids, such as toggle switches, volume control wheels, push buttons, remote controls, and directional microphones, which allow the wearer to hear better in various listening environments.
Types for Hearing Aid
In terms of size and feature, all these types vary. Some are so small that no one can even claim that you are wearing a hearing aid; some are so strong that it is possible to support even the most severe hearing loss. The best hearing aid for you depends on the level of equipment you need, hearing loss, hearing needs, lifestyle, budget, and personal preference you need. Typically larger hearing aids have bigger batteries and can last longer than smaller hearing aids. They can also have more features and have a lower price tag, such as directional microphones and telecoils (for telephone use). There are fewer features available for smaller hearing aids, but they are practically invisible.
About seven different types of hearing aids are available: Body, Eyeglass, Behind the Ear (BTE), In the Ear (ITE), In the Canal (ITC), Full In Canal (CIC), Receiver in the Canal (RIC) and Open Ear (OE). Although much of the hearing aid market consisted body and eyeglass aids 50 years ago, today they are just a small percentage of sales of hearing aids. This is because smaller and more sophisticated are the other types of hearing aids.
