The Focus of AI

• Research in AI is concerned with producing
  machines to automate tasks requiring intelligent
  behavior. (1)
• These automated tasks should be developed to
  assist people with everyday, necessary tasks that
  they cannot perform on their own.

Example AI and Hearing Aids

• A major issue with todays hearing aids deals
  with the ability to filter out Noise.

Why in Hearing Aids?

• In complex, challenging listening situations,
  hearing impaired patients continue to seek more
  effective technology.
• Current Algorithm
• Prediction based measures the input signal, to
  which an assumption is made, an algorithm is
  engaged and a prediction is made. This is similar
  to a Simple Reflex Agent.

Why in Hearing Aids? (Cont.)

• Better Implementation?
• Goal Based Agent Advanced technology hearing
  aid systems that perform sophisticated analysis
  of the communication situation and the acoustic
  environment, and adjust their performance based
  on whether or not specific performance goals are
  met. (2)

New Technology

• Oticon Syncro
• Syncro is an advanced technology, eight channel
  digital hearing instrument incorporating
  state-of-the-art implementations of adaptive
  directionality, noise management and wide dynamic
  range compression. (2)

The Reasoning behind the Problem

• Experts in Artificial Intelligence point out
  there is a difference in trying to create
  computer programs that imitate human brain
  physiology, versus those that try to understand
  basic challenges of the human brain while finding
  machine-based solutions to that problem (Ford
  Hayes, 2002).
