This invention relates to hearing aids and enhancement thereof in a novel manner.
Hearing aids generally are composed of three components (a) a small rigid shell shaped like a banana, (b) a thin plastic flexible tube extending outwardly from one end of the shell, and (c) a plastic perforated dome at the other end of the tube.
The shell contains microelectronic circuits which generate electrical or electronic sine waves that pass through the thin plastic tube. At the dome end, the waves vibrate a tympanic-disc that stimulates natural hearing bones, thereby amplifying sound to the wearer's ears. Some aids include a conductive wire within the thin tube at the dome end.
During sleep temperature in human ears is approximately 98° F. After awakening, humidity can cause condensation in the ear canals. This can cause ear wax to form in the canals which is undesirable and can cause problems with the hearing aid's ability to properly function.
A simple method has been determined which can ameliorate these problems. In particular, certain liquids, organic chemicals, can be applied upon the dome ends of the flexible tube. This can be supplemented, as well, by washing the ear canal with the liquids. These actions form a coupling between the ear canal surface and the domes, which maintain desired positions of the aids at least throughout a day.
Examples of the liquids are methanol, ethanol, propanol, butenol-1 acetone, and the like. These organic liquids are volatile solvents for organic materials, such as wax, ear wax, and other organic compositions. They are ideal for suppressing ear wax and other foreign materials in ear canals.
Hearing aid users can fill small containers of the liquids and maintain the contents for use throughout the day and at different locations. Users can wet their index-fingers and can easily apply the liquids to the dome ends several times, preferably 4 or 5 times in one day. Similar multiple applications are also preferable in their ear canals in one day.
The invention has been described with multiple components and embodiments. Variations can be made by those skilled in the art. It should be understood that all such variations are within the scope of the invention as well as the following claims.
