How Is the Modern Hearing Aid Different?

A hearing aid that you purchase this week, this month or this year will be very different in its look and construction than one purchased by someone 15 or 20 years ago.
In the past 10 years in fact, a number of changes have occurred in auditory technology.
Newer devices hold more cosmetic appeal than the older ones.
Leaving users more pleased with the aesthetic value.
They also offer a cleaner sound that is of a higher quality than those that were being produced just a few years ago.
This is due to the fact that changes have taken place in how sound is processed.
Over 90 percent of auditory devices use digital technology, as compared to the older analog technology that was once the norm.
Listening comfort is superior in the current design due to better automatic control of volume, as well as better frequency response.
These are traits that are appreciated by a new hearing aid user.
In years past, the dispenser would have to send a device back to the factory from if it needed an adjustment for a patient.
Today, there is no waiting period as the dispenser can easily adjust the newer models right in their office.
The newer auditory instruments for the hearing impaired have changed styles as progress has been made and innovations have been introduced.
There have also been dramatic improvements in the technology of the aids, or if you like, the circuitry.
In other words, the technology that is used to amplify sound is better.
The manner in which the equipment can be altered to fit the needs of the wearer has also been improved A conventional hearing aid uses analog technology for sound transmission.
The analog devices amplified speech as well as noise.
Until recently, this is the technology that was employed for all auditory apparatus.
While analog equipment is still used today, if your hearing undergoes changes over time, it may not be able to be reprogrammed.
The modern aids feature digital technology.
They are Digital Programmable (digitized sound processing or DSP) and they convert sound waves into digital signals.
These devices more complex in how they work than their analog counterpart.
A computer chip housed in the hearing aid takes the sound waves and turns them into numbers.
From there, the numbers are analyzed and manipulated according to algorithms and then programmed into the chip.
The computer is able to tell, mathematically speaking, if the sound entering the hearing device matches the sound wave pattern of speech or of noise.
It blocks out unwanted noise in the background that the user does not want to deal with, while at the same time selectively amplifying the sound waves that it identifies as speech.
