The listening device is incredible, now shouldn\'t something be said about my mobile phone? Melissa Pacey Mahaffey, AuD Jana Wells Rentz, AuD

Slide 3

Objectives Telecoil diagram How to choose for portable amplifier perfect mobile phones FCC controls & evaluations How to program for PDA use in iPFG Bluetooth alternatives for PDA utilize Other choices to associate with PDAs Resources

Slide 4

Telecoils

Slide 5

Can I utilize the PDA with my "T" catch? The telecoil was made to scaffold correspondence between the phone collector and portable amplifier It does this by transforming the attractive vitality radiated from the phone into electrical vitality The mobile phone does not create similar attractive field

Slide 6

What does the name "listening device good" mean? This does not generally mean a "telecoil" ought to be utilized to access PDA correspondences This essentially implies there is diminished Radio Frequency Energy contrasted with the normal passable level in PDA interchanges

Slide 7

Radio Frequency Energy (RFE) Current created for remote telecom and correspondences There is a permissible sum directed by the FCC, ANSI and EEI However, even the reasonable sum can meddle with therapeutic gear This is the reason mobile phones have been known to have a high incongruence rate with listening devices

Slide 8

How Do Cell Phones Work? At the point when utilizing a computerized PDA, the phone discussion is transmitted over a remote system utilizing radio waves. Mobile phones might be considered as complex walkie-talkies, that utilization a different transmission recurrence for talking and accepting signs, empowering concurrent two-way discussion.

Slide 9

How Do Cell Phones Work? In ordinary applications, wireless bearers hack the city up into cells over a city or district that are each around 10 square miles Each cell has a base station that comprises of a tower and a little building containing the radio gear

Slide 10

How Do Cell Phones Work? At the point when moving in an auto or by walking, correspondence between the base station and mobile phone empower programmed changing from cell to cell by means of radio recurrence (RF) transmissions RF discharges make electromagnetic fields around the PDAs which cause impedance with other electronic gadgets.

Slide 11

Digital Cell Phone Interference Basics notwithstanding the RF impedance, mobile phones produce different outflows alluded to an "attractive obstruction" This sort of emanation begins from the PDA\'s hardware and is autonomous of the fundamental impedance brought about by the RF transmission Sources of this kind of obstruction include: backdrop illumination on the show or keypad the battery the circuit board

Slide 12

Cell Phone/Hearing Aid Issue The expansion in PDA use as of late makes new difficulties for portable hearing assistant similarity, as more listening device clients are going "remote" When a wireless is held up to an amplifier, impedance might be heard as a humming, beating, murmuring, or whimpering clamor that can make discourse acknowledgment extremely troublesome, paying little mind to whether the listening device is in "mouthpiece" (M) or "telecoil" (T) mode

Slide 13

FCC Mandate 2005: every supplier make accessible 4 handsets appraised at any rate M3 2006: every supplier make accessible 5 handsets evaluated M3 or T3 furthermore, they needed to make these accessible for testing IN-STORE! *Sprint/Nextel, Alltel, AT&T/Cingular, Verizon, T-Mobile

Slide 14

What do the appraisals mean? Acoustic (receiver) coupling: M3,M4 T-loop coupling: T3,T4 The higher the rating, the lower the impedance, and better execution M1/T1: poor M2/T2: reasonable M3/T3: great M4/T4: fabulous

Slide 15

More about the evaluations Hearing guides are additionally appraised in this way To acquire the aggregate rating esteem, add the portable hearing assistant rating to the mobile phone rating i.e. Phonak instruments are all evaluated T2/M2. On the off chance that a patient acquired a telephone with a M3 rating, the aggregate rating worth would be M5

Slide 16

Tips for Patients ought to search for PDAs evaluated M3/T3 or M4/T4 This does not ensure that these telephones will be sans impedance with a specific listening device display, however will bring about a joined ANSI 63.19 prescient rating of 5-6, showing that the mobile phone/portable amplifier blend is "reasonable for typical utilize" or "astounding", separately. Patients ought to be reminded that other telephone choices, for example, console presentations and backdrop illumination can bring about extra impedance. Kill these when conceivable!

Slide 17

Features to search for Options that may assist those with listening to weakness utilize mobile phones: Vibrating ringer Choice of ring tones Volume control Visual presentations to demonstrate call capacities – i.e. being used, no administration, and so forth Text informing, email, texting T-curl similarity TTY good Neckloop or Silhouette perfect 2.5 mm sound jack Information civility of w ww.accesswireless.org

Resources http://www.fcc.gov/cgb/consumerfacts/accessiblewireless.html www.phonescoop.com http://www.accesswireless.org/Cell telephone sites: Sprint—look "portable amplifier perfect" Alltel—telephones & extras/incapacity get to/discourse & listening to Verizon—store AT&T—seek "listening device perfect" T-versatile—"portable hearing assistant telephones"

Slide 22

Software Programming Touchless or "Simple" T-loop and receiver choices How this functions with land lines & mobile phones Manually selectable telephone programs Common programming tips to enhance telephone use

Slide 23

Touchless/"Simple" Phone Touchless T-curls are prevalent choices and accessible from each significant maker The phone program is naturally enacted when the telephone handset is put before the portable hearing assistant The reed-hand-off switch inside the guide identifies the nearness of attractive vitality spilling from the telephone and initiates the telephone program

Slide 24

Touchless/"Simple" Phone If there is not adequate attractive vitality (as in PDAs) a magnet can be set on the handset to actuate this switch Some producers, (for example, Phonak) permit the Easy or programmed telephone program to be designed as a T-loop, mouthpiece or consolidated M+T input The decision depends on the kind of phone(s) utilized by the patient

Slide 25

Touchless/"Simple" Phone If the patient is utilizing a M evaluated PDA, then an acoustic or receiver setting ought to be chosen If the patient\'s wireless has a T rating, then a T-curl setting can be chosen More frequently than not, patients utilize an assortment of telephones amid the day and a joined M+T might be the best choice Patients may likewise like to have M chosen for one ear, and T for the other ear

Slide 26

Manual Phone Programs Most makers additionally permit the utilization of manual telephone programs so that the patient can choose the telephone program These can be arranged as either a mouthpiece ("acoustic"), T-curl or consolidated M+T setting Again, the decision depends on the phone(s) the patient will utilize – if their PDA has a T rating a T-curl might be utilized, generally a receiver setting is best sometimes, patients may wish to have an amplifier setting in one ear and a T-loop in the other – a few makers make this conceivable through programming

Slide 27

Programming Tips Whether utilizing a T-loop or amplifier setting, the accompanying tips may enhance patient\'s telephone encounter: Increasing general pick up, or pick up for uproarious sounds (G80), particularly between 500 Hz and 3000 Hz Ensuring MPO is sufficiently high – deficient headroom will make discourse sound "stifled" Decreasing pressure for more direct handling Increasing quality of clamor cancelation if T-loop is "humming" – i.e. set to direct or solid

Slide 28

What about without hands? Numerous states now require sans hands PDA use by law There are a few courses for your patients to consent to these laws and utilize their amplifiers too The accompanying choices concentrate on utilizing Bluetooth streamers or outline and neckloop items to connect a patient\'s listening devices to their PDA

Slide 29

What is Bluetooth ? Where did the name "Bluetooth" begin it is named after a Danish Viking and King, Harald Blåtand (interpreted as Bluetooth in English), who lived in the last part of the tenth century. Harald Blåtand joined together and controlled Denmark and Norway (thus the motivation on the name: joining gadgets through Bluetooth). * Bluetooth empowers gadgets to discuss remotely with each other when they are in range. * Bluetooth gadgets utilize a safe, all inclusive unlicensed short-go radio interchanges framework, so they don\'t need to be in observable pathway of each other.* *Wikipedia.org

Slide 30

Bluetooth Hearing guide producers are exploiting this innovation – more choices turning out each year Bluetooth frill - Phonak iCom, Oticon Streamer, Siemens Tek, Starkey ELI Bluetooth without hands mics that use outline and neckloop associations FM transmitter with included Bluetooth work

Slide 31

Patient sets Bluetooth streamer with mobile phone Wireless association with amplifiers Cell telephone discussion is gushed to listening to instruments – BINAURALLY – through the Bluetooth gadget Streamer goes about as sans hands mouthpiece - their voice is spilled back to individual on the flip side of the telephone Additionally can give persistent access to most any Bluetooth gadget – GPS, PC, and so on Bluetooth Streamers

Slide 32

Bluetooth Streamers Starkey Eli connects straightforwardly to HA by means of DAI and sound shoe Some streamers offer extra components, for example, Music gushing by means of link – interface with MP3, iPod, and so on Audio gushing by means of link – interface with DVD player, portable workstation, and so on FM – can connect to general FM recipient, for example, MLxi – right now this is elite to Phonak
