can i use the cell phone with my t button
Can I use the cell phone with my “T” button?
  • The telecoil was created to bridge communication between the telephone receiver and hearing aid
  • It does this by turning the magnetic energy emitted from the telephone into electrical energy
  • The cell phone does not produce the same magnetic field
what does the label hearing aid compatible mean
What does the label “hearing aid compatible” mean?
  • This does not always mean a “telecoil” should be used to gain access to cell phone communications
  • This simply means there is reduced Radio Frequency Energy compared to the average allowable level in cell phone communications
radio frequency energy rfe
Radio Frequency Energy (RFE)
  • Current generated for wireless broadcasting and communications
  • There is an allowable amount regulated by the FCC, ANSI and EEI
  • However, even the allowable amount can interfere with medical equipment
  • This is why cell phones have been known to have a high incompatibility rate with hearing aids
how do cell phones work
How Do Cell Phones Work?
  • When using a digital cell phone, the telephone conversation is transmitted over a wireless network using radio waves.
  • Cell phones may be thought of as sophisticated walkie-talkies, that use a separate transmission frequency for talking and receiving signals, enabling simultaneous two-way conversation.
how do cell phones work9
How Do Cell Phones Work?
  • In typical applications, cell phone carriers chop the city up into cells across a city or region that are each around 10 square miles
  • Each cell has a base station that consists of a tower and a small building containing the radio equipment
how do cell phones work10
How Do Cell Phones Work?
  • When moving in a car or on foot, communication between the base station and cell phone enable automatic switching from cell to cell via radio frequency (RF) transmissions
  • RF emissions create electromagnetic fields around the cell phones which cause interference with other electronic devices.
digital cell phone interference basics
Digital Cell Phone Interference Basics
  • In addition to the RF interference, cell phones generate other emissions referred to a “magnetic interference“
  • This type of emission originates from the cell phone's electronics and is independent of the basic interference caused by the RF transmission
  • Sources of this type of interference include:
    • backlighting on the display or keypad
    • the battery
    • the circuit board
cell phone hearing aid issue
Cell Phone/Hearing Aid Issue
  • The increase in cell phone use in recent years creates new challenges for hearing aid compatibility, as more and more hearing aid users are going “wireless”
  • When a cell phone is held up to a hearing aid, interference may be heard as a buzzing, pulsing, humming, or whining noise that can make speech recognition very difficult, regardless of whether the hearing aid is in “microphone” (M) or “telecoil” (T) mode
fcc mandate
FCC Mandate
  • 2005: each provider make available 4 handsets rated at least M3
  • 2006: each provider make available 5 handsets rated M3 or T3
  • In addition, they had to make all of these available for testing IN-STORE!

*Sprint/Nextel, Alltel, AT&T/Cingular, Verizon, T-Mobile

what do the ratings mean
What do the ratings mean?
  • Acoustic (microphone) coupling: M3,M4
  • T-coil coupling: T3,T4
  • The higher the rating, the lower the interference, and better performance
      • M1/T1: poor
      • M2/T2: fair
      • M3/T3: good
      • M4/T4: excellent
more about the ratings
More about the ratings
  • Hearing aids are also rated in this manner
  • To obtain the total rating value, add the hearing aid rating to the cell phone rating
    • i.e. Phonak instruments are all rated T2/M2. If a patient purchased a phone with an M3 rating, the total rating value would be M5
tips for patients
Tips for Patients
  • Patients should look for cell phones rated M3/T3 or M4/T4
  • This does not guarantee that these phones will be interference-free with a particular hearing aid model, but will result in a combined ANSI 63.19 predictive rating of 5-6, indicating that the cell phone/hearing aid combination is “suitable for normal use” or “excellent”, respectively.
  • Patients should be reminded that other phone options such as keyboard displays and backlighting can cause additional interference. Turn these off when possible!
features to look for
Features to look for
  • Options that may help those with hearing impairment use cell phones:
    • Vibrating ringer
    • Choice of ring tones
    • Volume control
    • Visual displays to indicate call functions – i.e. in use, no service, etc
    • Text messaging, email, instant messaging
    • T-coil compatibility
    • TTY compatible
    • Neckloop or Silhouette compatible
    • 2.5 mm audio jack

software programming
Software Programming
  • Touchless or “Easy” T-coil and microphone options
    • How this works with land lines & cell phones
  • Manually selectable phone programs
  • Common programming tips to improve phone usage
touchless easy phone
Touchless / “Easy” Phone
  • Touchless T-coils are popular options and available from every major manufacturer
  • The telephone program is automatically activated when the phone handset is placed in front of the hearing aid
  • The reed-relay switch inside the aid detects the presence of magnetic energy leaking from the phone and activates the phone program
touchless easy phone24
Touchless / “Easy” Phone
  • If there is not sufficient magnetic energy (as in cell phones) a magnet can be placed on the handset to activate this switch
  • Some manufacturers (such as Phonak) allow the Easy or automatic phone program to be configured as a T-coil, microphone or combined M+T input
  • The choice is based on the type of phone(s) used by the patient
touchless easy phone25
Touchless / “Easy” Phone
  • If the patient is using an M rated cell phone, then an acoustic or microphone setting should be selected
  • If the patient’s cell phone has a T rating, then a T-coil setting can be selected
  • More often than not, patients use a variety of phones during the day and a combined M+T may be the best option
  • Patients may also prefer to have M selected for one ear, and T for the other ear
manual phone programs
Manual Phone Programs
  • Most manufacturers also allow the use of manual phone programs so that the patient can select the phone program
  • These can be configured as either a microphone (“acoustic”), T-coil or combined M+T setting
  • Again, the choice is based on the phone(s) the patient will be using – if their cell phone has a T rating a T-coil may be used, otherwise a microphone setting is best
  • In some cases, patients may wish to have a microphone setting in one ear and a T-coil in the other – some manufacturers make this possible through programming
programming tips
Programming Tips
  • Whether using a T-coil or microphone setting, the following tips may improve patient’s phone experience:
    • Increasing overall gain, or gain for loud sounds (G80), especially between 500 Hz and 3000 Hz
    • Ensuring MPO is high enough – insufficient headroom will make speech sound “muffled”
    • Decreasing compression for more linear processing
    • Increasing strength of noise cancellation if T-coil is “buzzing” – i.e. set to moderate or strong
what about hands free
What about hands-free?
  • Many states now require hands-free cell phone use by law
  • There are several ways for your patients to comply with these laws and use their hearing aids too
  • The following options focus on using Bluetooth streamers or silhouette and neckloop products to link a patient’s hearing aids to their cell phone
what is bluetooth
What is Bluetooth ?
  • Where did the name “Bluetooth” originate
    • it is named after a Danish Viking and King, Harald Blåtand (translated as Bluetooth in English), who lived in the latter part of the 10th century. Harald Blåtand united and controlled Denmark and Norway (hence the inspiration on the name: uniting devices through Bluetooth). *
  • Bluetooth enables devices to communicate wirelessly with each other when they are in range. *
  • Bluetooth devices use a secure, globally unlicensed short-range radio communications system, so they do not have to be in line of sight of each other.*

what to do with old cell phone
What to do with old cell phone?

www.cellphonesforsoldiers.com

  • Started in 2004 by a 12 and 13-year old brother and sister in Massachusetts
  • Goal is to help soldiers serving overseas call home
  • Take old cell phones (any model, no matter how old) and recycle them via ReCellular
  • Money received from ReCellular for each phone donated is then used to buy prepaid calling cards for soldiers
  • They work with all branches of the US military
