Well for these ones, for better understanding the person talking had to talk by positioning him in direct line with this cone (device) to enable sound to enter the ear efficiently.
Recent progress in science and technology provided scientific answer to the question of how do aids work and thus emerged a new generation of these really handy devices. Electronics gave small but powerful chips whilst the computer science enabled efficient programming based on a customers need.

How Do Hearing Aids Work, Answer By Technology:
The advent of technology has made possible to amplify certain frequencies in the sound more than the others. This gives much power to the aid design as this enables the manufacturer to program the circuit according to the patients need.
