The increased expense of digital hearing aids, compared with conventional analog aids, is justified by the substantial advantages they provide.
The proliferation of digital technology and continued miniaturization of sound-processing hardware has led to the development of a new generation of digital hearing aids. These aids offer complex sound-processing algorithms made possible through replacement of capacitors and resistors with computer software, and are purported to offer substantial benefit over conventional analog hearing aids by being more adaptable to an individual's pattern of hearing loss. However, digital aids are up to 5 times more expensive.
