NON-DIGITAL HEARING AIDS Conventional or Analog hearing aids are the oldest and most basic hearing aid technology. You may see this technology referred to by several different names: Conventional Analog Linear Class A Class D Basic or Standard Conventional hearing aids have a set frequency response that has very limited adjustments. They typically include a volume control, which must be manually adjusted for different situations. Limitations of this technology are that background noise is overwhelming and that loud sounds can be uncomfortably loud. Some manufacturers have discontinued this technology and replaced it with non-programmable digital. Analog Programmable Hearing Aids were a transition technology between standard analog conventional aids and today’s digital technology. These aids used analog technology, but enabled multiple memories and could be computer programmed for increased flexibility in different listening situations. With the explosion of digital technology offerings and increased affordability of digital hearing aids, Analog Programmable hearing aids are now obsolete. These hearing aids were popular from their introduction in early 1990’s until 2003 when they were overtaken by digital aids in performance and affordability. BACK TO ABOUT HEARING AIDS
