Going Wireless.

• What we hope to accomplish today
• Wireless specific advancements in Hearing Aids
• New accessories available
• Answer the question, What is Bluetooth?
• Discuss how Bluetooth works
• Examples of how to apply the new technology
• Anything else?

3
What has changed?

• Technology is moving more and more in the
  direction of wireless and hands free
• Hearing aid manufacturers have identified this
  problem and over the last several years have been
  releasing products to help!

4
So what exactly are you talking about?

• Weve made hearing aids wireless! They can
  communicate

• Between two hearing instruments
• Between a bluetooth accessory, the hearing
  instruments and the world of communication
  devices

5
How do we make Hearing Aids Wireless?

• Wireless technology means the instruments are
  able to transmit and receive wireless commands
  and stream external audio signals.
• The requires a wireless antenna in the hearing
  aid.

6
Which Hearing Aids are Wireless?

• Phonak and other manufacturers have been making
  wireless instruments 3 years
• Any style of the new technology hearing aids can
  be made wireless-- as long as we can fit that
  antenna inside!
• Standard behind the ear
• Mini behind the ear
• Most custom products except the completely in the
  canal (CIC)
• Premium, Advanced, and Basic technology levels as
  well!

7
Once you have wireless hearing aids.

• The possibilities are endless!
• Allows for the addition of wireless accessories
• Gives access to so many more features to help in
  challenging listening situations!!
• Wireless accessories vary with your listening
  goals

Lets back up for a minute and talk
BluetoothWhat is Bluetooth?

• Bluetooth is a short-range wireless setup used to
  create personal networks
• Developed in 1996 to have a standard for cell
  phone and computer communication
• It uses an unlicensed radio frequency bandwidth
  of 2.4 2.485GHz
• Is omni-directional and is able to penetrate
  solid objects

16
What is Bluetooth?

• Bluetooth is used for a variety of applications,
  such as
• Wireless control and communication between a
  mobile phone and a wireless headset
• Wireless communication between computers and
  input devices, such as keyboards, printers and
  mice
• Wireless replacement of serial port applications,
  such as GPS receivers and medical devices (i.e.
  HiPro boxes/ NoahLinks)
• Wireless networking of computers, where small
  amounts of information exchange occur
• Wireless transfer of contact information and
  calendar details

17
Digital Transmission Technologies

• Power efficiency measure power / data rate
• Bluetooth 100 ?W/kbit/s
• Inductive 5 ?W/kbit/s

18
Bluetooth Different Profiles

• Think of profiles as capabilities or features
• Both devices have to support the same profile for
  a feature to work
• There are many different profiles available

19
Bluetooth Profiles to know about

• Profiles important to you include
• Headset Profile (HSP)
• Hands-Free Profile (HFP)
• Advanced Audio Distribution Profile (A2DP)

20
Bluetooth HSP

• Headset Profile (HSP)
• This is the most commonly used profile and allows
  mobile phones to communicate with wireless
  headsets
• It only allows to ability to ring, adjust the
  volume, answer a call and hang up

21
Bluetooth HFP

• Hands-Free Profile (HFP)
• This is commonly used to allow communication with
  a car hands free system
• The extra features that HFP allows are last
  number redial, call waiting and voice dialing
• Most Bluetooth headsets support both HSP and HFP
  profiles.

22
Bluetooth A2DP

• Advanced Audio Distribution Profile (A2DP)
• This profile is used to define how high quality
  mono and stereo audio information is streamed
  from one device to another
• Example
• Audio from a television or stereo to a wireless
  headset

23
Bluetooth TermsGrouping, Pairing Connecting.
Oh My!

• There are three terms that are frequently
  interchanged, however, need to be clearly
  defined.
• Grouping occurs in the hearing aid software. It
  is when an iCom/ Streamer is attached to hearing
  instruments to create a hearing system.
• Pairing is when a trusted relationship is
  established between two Bluetooth devices. The
  devices place each other on their buddy list
• Connecting is when two previously paired devices
  recognize each other and start talking.

24
Bluetooth Pairing

• Pairing occurs when two devices agree that it is
  safe to communicate with one another and create a
  connection
• To pair two compatible devices, a shared passkey
  (password) is needed
• Many devices use the standard 0000, especially
  those without keyboards for manual number input
• Once two devices are paired, they need not be
  re-paired unless either device is reset or the
  pairing has been deleted

25
Bluetooth Pairing

• The pairing process is
• Device A (ex cell phone) searches for other
  Bluetooth devices
• Device B (streamer) is found by Device A
• Device A asks for a passkey (any user generated
  code) and sends it to Device B
• Device B sends the passkey back to Device A and
  creates a trusted pairing if both passkeys are
  the same
• Connected!

26
Other Considerations

• Bluetooth is a one-to-one connection. Two
  receiving devices cannot be connected to two
  devices at the same time.
• For example, a husband and wife, each with their
  own iCom, would each need their own television
  transmitter.

27
So how do we apply all of this?
Endless possibilities!
