During the summer of 2020 when the world shut down due to the COVID pandemic, medical office visits also dropped off precipitously with only emergency cases being seen in person. However, for more mundane medical issues like a clogged ear or hearing loss complaints, telemedicine visits were utilized instead. However, it is very difficult to evaluate and treat an ear issue via telemedicine without being able to look in the ear or obtain a hearing test.
In order to obtain some of this necessary ear information for telemedicine visits, patients were encouraged to purchase digital otoscopes and online hearing tests became a "thing." One of THE most accurate, easy, and fast way of obtaining a hearing test online was one developed by Dr. Stephane Pigeon, a research engineer and sound designer in Belgium. His original online hearing test can be found here.
Once patients were able to come back to the office in-person and a hearing test was able to be formally repeated, there was a surprisingly good agreement between the online hearing test and a formal traditionally performed hearing test conducted in a soundproof booth. Dr. Christopher Chang, an ENT doctor in Virginia, was so impressed with the performance of the audio tones developed by Dr. Pigeon that he obtained licensing to create CheckHearing.org which further improved on his original code and warble tone use.
From that point forward, additional modules were created to further improve the overall user experience beyond just a hearing test including tinnitus matching, sound meter, SRT, WIN, store, etc.
