Shopping for devices •  Before you leave the store or purchase online, inves0gate the Return Policy •  Make sure you have the User Guide/User Manual with the device •  Try your device in places that you frequent (e.g., home, work, school, etc.) to make sure there is not interference Informa0on at your finger0ps Program seangs Make and model of your hearing device •  For example: P1 = everyday, P2 = FM only, P3 = FM + HA, P4 = noise •  For example: Advanced Bionics Harmony, Phonak Nios Micro III… •  They all have Customer Service Phone number to the manufacturer of your device departments dedicated to consumers Phone number for your audiologist •  If you don’t know what your program seangs are… User Guide / User Manual •  Not only for your device but also for what you’re trying to connect to TERMINOLOGY Microphone loca0on Where do I hold this thing? Why is it important to know this? Hearing aids www.ac0vears.com/images/productTypes3.jpg Cochlear implants Ear level processors Body worn processors What is a T-­‐coil? •  T-­‐coil (telecoil) is small coil of wire built into HAs or CIs and is designed to pick up magne0c signal from assis0ve listening systems and HA compa0ble telephones •  T-­‐coil = Telecoil = T-­‐switch = Telephone Switch Mixing ra0o •  This is the rela0onship between your auxiliary input (either via plugging into your CI/HA or via T-­‐coil) compared to your environmental microphone •  Be sure to check with your audiologist if you do not know what your mixing ra0o is Mixing Ra0o Auxiliary only Auxiliary + Environmental microphone •  All of the signal comes through the audio cable or T-­‐coil •  You will not be able to hear things around you or your own voice •  You will be able to hear the signal through your audio cable or T-­‐coil •  You will be able to hear what is going on around you What is Bluetooth? •  It’s a wireless and digital technology that allows certain compa0ble devices to communicate with each other wirelessly –  You need to “pair” the devices before it will work –  Most of the 0me, the code is either “0000” or “1234” but be sure to check the manual CONNECTING Ways to connect to HAT INDIRECT •  Use your environmental microphone on your HA or CI DIRECT •  Use a patch/axuiliary/audio cable and adapter to plug directly into your HA, CI or via your FM system T-­‐COIL •  Accessed through specific program seang on your HA or CI What can I connect to? Telephone Cellphone Videophone Media (CD, MP3, iPod, DVD, computer, portable gaming systems, TV) INDIRECT •  Increase the clarity and/or loudness of the signal by improving the acous0cs •  The environmental microphone receives the sound •  When using hearing aids with the phone, may need a cushion to reduce feedback (i.e., that squealing sound) INDIRECT DIRECT •  Any wired connec0on between the CI , HA or FM and another device •  Possible seangs –  Auxiliary signal only •  Will not be able to hear any environmental sounds (including your own voice) –  Auxiliary signal + environmental microphone •  Can hear environmental sounds around you DIRECT + DIRECT Cochlear implant recipients •  Be sure to directly connect to BATTERY POWERED devices only if using a standard auxiliary cable •  If connec0ng to something that plugs into the wall (e.g., television or computer), be sure to use the recommended cable with surge protec0on T-­‐COIL Wired neckloop Wired induc0on earhook(s) Bluetooth neckloop Bluetooth induc0on earhook(s) Check with your audiologist if you are not sure you have this seang on your HA or CI ASSISTIVE LISTENING DEVICES Assis0ve Listening Devices •  How can ALDs help? They can: –  Bring the sound louder to you –  Improve the clarity –  Lessen the effect of background noise •  Parts: –  TransmiUer (microphone) –  Receiver •  Having a T-­‐coil on your hearing aid and/or cochlear implant gives you more op0ons Types of Assis0ve Listening Devices Frequency Modula0on (FM) Infrared (IR) Induc0on Loop Personal ALD Note for cochlear implant users •  See if your patch cable and/or external microphone might help you instead…less expensive! •  Check with your audiologist about which cable should be used (e.g., baUery powered vs. wall powered) FM system •  Signal is transmiUed via FM (radio signal) waves to a receiver used by the listener •  Applica0ons –  Classrooms –  Theaters –  Mee0ng spaces –  Places of worship –  Car –  Restaurants TransmiUers Microphone styles Receivers Hearing Aid Cochlear Implant Soundfield Toteable Classroom Infrared Devices •  Signal is transmiUed via infrared (light) waves to a receiver used by the listener •  Applica0ons –  Theaters –  Classrooms –  Mee0ng spaces Infrared Devices Receivers TransmiIer Induc0on Loop Systems •  Physical wire is laid down around the area to be amplified •  Signal is transmiUed via the electromagne0c field and received via the T-­‐coil in your HA or CI •  Applica0ons –
