A quick look this morning at two very important hearing aid technologies that have been developed over the last decade. The two crucial hearing aid technologies I want to look at are Digital Noise Reduction (DNR) and Digital Speech Enhancement (DSE).
Digital noise reduction could be argued as the most important advancement in hearing aid technology. Essentially DNR is designed to reduce gain. In less technical terms, DNR is designed to reduce unwanted noise and allow voices to stand out. It has not always been viewed as completely successful but it is a crucial piece of the technology of hearing aids.
Digital Speech Enhancement is designed to enhance the volume of speech. The technology is able to recognize speech apart from other noises and increase it.
Working in tandem, DNR and DSE have dramatically increased the quality of hearing aids.
