1. Taking the Digital Leap. The author stresses that compared to earlier technology, current hearing aids are less noisy, capable of more signal processing, more efficient in amplifying acoustic signals, more capable of meeting specific needs, and certainly much smaller and more cosmetically acceptable. Battery performance has also improved.
Current batteries are smaller and more power-efficient.
The author describes the differences between analog and digital processing and the use of an algorithm for processing sound. The author also considers the impact of aging and central auditory processing disorders on the ability to receive acoustic information and process it correctly. State of the Art on the Development of the Implantable Hearing Device for Partial Hearing Loss. Otolaryngologic Clinics of North America. The author describes animal studies of the feasibility of these designs.
