Only about 20 percent of people with hearing problems having a hearing aid, it could be lack of understanding of how hearing aids do work. When hearing aids were first introduced they were shaped like miniature megaphones, or cones, to focus the sound coming in to one point as it entered the ear. The person speaking had to be in a direct line with the cone for the sound to be captured and travel into the ear.
As the cause of hearing problems became better understood, and better electronic technology was developed, it altered the answer to the question of how do hearing aids work. Recent advances in technology have enabled the development of hearing aids with programmable computer chips to control many aspects of the aids’ functions that can fit innocuously into the ear. Some are so small they will fit into the ear with hardly any visible indication on the outside that you are even wearing one. There are others that look like a small wireless earphone.
There are two basic types of hearing aids. One is analog and the other is digital. Analog simply converts sound waves into amplified electrical signals. Your hear aid specialist will send your hearing aid prescription to the manufacturer and how it is programmed determines how the hearing aids will work for each individual.
Digital advances in hearing aid technology has redefined how modern hearing aids work. This digital advancement has enabled certain frequencies to be amplified more than others and also to indicate the direction from which the sound is coming. Digital hearing aids converts the sound into a binary number sequence where it is adjusted according to the needs of the patient and the sound frequencies are adjusted in volume to meet the individual needs.
Digital circuitry is being used in all types of hearing aids and this allows them to be programmed to detect sound from all directions. They can also be programmed to eliminate certain sounds for people who have trouble understanding words in the presence of background sounds. This can also determine how hearing aids do work by amplifying only sounds within a specific range while muting noise in other frequency ranges.
If you are suffering from hearing loss, regardless of the reason, there may be a hearing aid that can help you hear the world around you once again. While some auditory deficiencies cannot be helped by hearing aids, knowing how hearing aids do work can help patients and doctors make a decision about what is right for each person. Tremendous advances have been made in how hearing aids work.
