There are essentially
three levels of hearing aid technology. We refer to
these as analog, digitally programmable, and digital.
- ANALOG technology is the technology that has been
around for many decades. Analog technology is basic
technology and offers limited adjustment capability.
It is the LEAST expensive.
- DIGITALLY PROGRAMMABLE technology is the "middle
grade" technology. Digitally programmable units are
analog units digitally controlled by the computer in
the office to adjust the sounds of the hearing aid.
- DIGITAL technology is the most sophisticated
hearing aid technology. Digital technology gives the
audiologist maximum control over sound quality and
sound processing characteristics. There are
qualitative indications that digital instruments do
outperform digitally programmable and analog hearing
aids. Digitals are not perfect, but they are very
good. Digital hearing aids have been widely available
since 1996.
