Are All Hearing Aids The Same?

Hearing loss is a problem for many people across all ages. Whether it is diagnosed as mild, moderate, or severe, it causes communication difficulties in everyday lives. This impairment must never be neglected or untreated for what it is since it may lead to complications.


Hearing Aids

These are devices meant to help treat hearing loss that are basically made to amplify sound. Through the many years of its existence, analog hearing devices were introduced first. These were, by then, bulkier and amplified all sounds caught including bothersome noise.


Presently, digital hearing aids flood the market for those in need. These newer devices are leaps of improvement from the analog years in that they have electronic chips inside that fine-tunes the sound from speech and even eliminates background noise in some expensive models.


They are all the same?

If you have seen one, you have seen them all, you might think of hearing aids. They may look the same, but they are not exactly the same; it’s a “yes” and a “no” at the same time.


All hearing aid devices share the same similarity in components. As a whole:

  • they have miniature batteries to power the entire set-up;
  • microphones that catch the sounds in the environment;
  • circuits that process then amplify the sound for transmission;
  • and a tiny speaker to deliver the sound.


What sets them apart?

The specific differences between hearing aids would fall into three distinct categories, namely:


  • Technology used in the design. In the evolution of hearing aids, analog hearing aids were far less superior than the current digital ones. The continuing innovation of digital technology has put the differences down to the microscopic level.


Sound capture and refinements has made it clearer than before. Some devices can stay immersed in water for a time by purpose.


  • Layout of the device. Hearing aids may be located behind the ear (BTE), on the ear (OTE), in the ear (ITE), in the [ear] canal (ITC), or completely in the [ear] canal (CIC). These are all compact, single component devices for mild and moderate hearing loss.


For severe hearing loss, and even the deaf, the two-component cochlear implant is best.


  • Added features spell a difference. There are devices that have directional microphones, audio inputs for television, telephone coil, and some even have Bluetooth connectivity for a wider range of adaptability.
