Advances in hearing aid technology mean that we now have many more functions in hearing aids than ever before. This allows for individual lifestyle and needs to be taken into account when selecting which hearing aid is right for you. The cost of the hearing aid generally depends on the technology and the features that the hearing includes and not necessarily how the hearing aid looks.
Digital Hearing Aids Technology
Digital hearing aids first came to market in 1987 with two manufacturers introducing hearing aids with digital signal processing (DSP) before the end of the 1980s. While high-tech for their time, these hearing aids had little success and were soon abandoned due to their large size and high battery drain. Digital hearing aids can divide the sounds into many components based on frequency, time, or intensity information and apply different algorithms to manipulate the sound for a given individual. This results in a more precise tuning of the sound shape for the hearing impaired user. Digital hearing aids automatically perform feedback suppression, speech enhancement, noise reduction, and pattern recognition. Digital hearing aids can also monitor the battery voltage resulting in less drain and increased battery life.
The best part of this technology is that all these adjustments happen automatically for the user. So, as complicated as this all sounds, the user doesn
