![]() Advancement in genetics and medicine might one day even correct nerve damage and thus alleviate hearing loss completely. Users will hopefully be able to control and fine-tune their hearing aids themselves. ![]() ![]() Some ultra-modern designs today allow a pair of hearing aids to communicate wirelessly with each other (left and right ear), providing ever more precise sounds. The future of the hearing aid timeline looks bright and fascinating: the introduction of wireless technology and Bluetooth will allow users to link up with technology in their surroundings (cellphones, HiFi, TVs, etc.). DSPs are the cornerstone of today’s hearing aids, making up the vast majority of sales in the US. The form factor shrank substantially and the proliferation of channels and bands allowed for vastly more granular sound filtering and amplification. The 1980-the 2000s: The Digital Hearing Aid Ageīy the time the 1980s rolled around, companies started introducing digital signal processors (DSPs) into their hearing aid designs. Analog hearing aids can still be found to the present day. While analog hearing aid technology allowed for far more comfort, discreetness, and sound quality, their ability to filter noise and speech was quite limited. The prototypes for today’s Behind and In the Ear ( BTE/ITE) arrived on the market, containing analog technology. The introduction of transistors was a massive step forward, allowing for the production of far more portable hearing aids. The 1950s-80s: The Transistor Hearing Aid Age Vacuum tubes became smaller but remained awkward over the next decade until transistors appeared. However, they required two batteries, so costs were rather high at the time. Hanson, he called his hearing aid the “Vactuphone.” This hearing aid technology was able to address more severe hearing loss. 1920-40s: The Vacuum Tube Ageīy the 1940s, the more portable vacuum tube was introduced. As such, these carbon models were ineffective for serious hearing loss. The carbon microphone reproduced sound by using sound waves to compress carbon against a diaphragm. While based on the telephone principle, Alexander Graham Bell was not involved in their development. 1900-the 1920s: The Telephone AgeĮlectric hearings aids came into play at the beginning of the 20 th century, with the advent of the carbon microphone. Some even became fashion statements, as they were adapted to headbands and hats or designed to look like flowers tucked behind a lady’s ear. Trumpet hearing aids came in a number of forms, with names like London domes, pipe trumpets, and Dippers (pictured here). These non-electric aids were essentially sophisticated, powerful, and fairly effective ways of amplifying and directing sound, much like cupping a hand behind your ear. Trumpet hearing aids were the primary hearing aid until the turn of the 20 th century. Leurechon wrote the world’s first known description of a hearing aid-the ear trumpet. The first modern “devices” were introduced in the 17 th Century, by French mathematician Jean Leurechon. ![]() Let’s check out the hearing aid timeline: 1600-the 1900s: The Trumpet Hearing Aid Age Luckily humanity has bridged those rather dim times into the digital hearing aid age. In 100 A.D., Greek physician Archigenes suggested blowing trumpets into a patient’s ear as a cure for deafness. Hearing aids have been around for longer than the English language.
