Analog Technology


Analog Wave analog technology hearing aid


Definition :

An analog signal is one in which a base carrier's alternating current frequency is modified in some way, such as by amplifying the strength of the signal or varying the frequency, in order to add information to the signal.


An analog signal can be represented as a series of sine wave s. The term originated because the modulation of the carrier wave is analogous to the fluctuations of the human voice or other sound that is being transmitted.


A nominally continuous electrical signal that varies in amplitude or frequency in response to changes in sound, light, heat, position, or pressure.

Analog Processing:


Analog technology has been around for decades. It's not that complicated a concept and it's fairly inexpensive to use.


It is the process of taking an audio or video signal (in most cases, the human voice) and translating it into electronic pulses.


Analog Hearing Aid:

An analog hearing aid employs miniature devices, such as microphones, amplifiers, and resistors to alter an acoustic signal (a sound) electronically. The altered signal is then converted back to a sound wave and played into the ear canal.


Advantages of analog hearing aid :

  • Due to linier amplification-user sometimes prefer analog hearing aid.
  • For Profound hearing loss user gets more amplification in analog hearing aid than digital hearing aid.
  • Some are programmable for different environments and can be programmed for changing levels of hearing loss.
  • Cost effective than that of digital hearing aid.
  • Durable compared to digital models.
  • Battery consumption is less.
  • Simple to use.
  • Disadvantages of analog hearing aid:

  • Not suitable for all environmental situations.
  • Only three types of model variety available in the market.
  • Analog hearing aids are getting phase out from market.
  • Not fit for today's lifestyle.
