4 Listening is an Active Sport I can listen in noise for a few minutes, but not for an hourI can listen in an ideal classroom without technology for an hour, but not all dayI can run around the block, but I can’t run in a marathonFor hard of hearing people, the journey is at full speed.The hearing people are allowed to walk.

8 Cultural Labels Deaf deaf Hard of hearing part of Deaf culture/communitydeafness is an identitydeafcannot hear well even with hearing aidculturally hearing (translation: isolated)Hard of hearingmay hear some with hearing aidtoo deaf to be hearing and too hearing to be DeafMy spouse thinks I can’t hear

11 Hearing Aid Facts Hearing aids do not “fix” hearing loss not like glassesexternal amplifier has to go through “bad” earProblems with hearing aidsamplify background noisecan have interference from equipmentHearing aid helps, but is not total solution
12 Hearing Aid “Quality” Price does not always mean better fit Individual preferenceFamiliar toneListening environmentsGadget comfort levelFitting can be complexEarmoldProgrammingTuningHigh cost digital aidsLow cost “invisible” aids
14 Fact: Lipreading is an Art Only when I want toget myself in trouble...You’re hard of hearing!So you can lipread, right?Hollywood Teaches Us:When someone loses their hearing they are able to lipread as compensationReality Is:Lipreading is a difficult skill that few are able to master
15 An Example ? Can you bowl next week against the Tow Trucks? Which Team is it Really?Navy Department 20Navy Department 40Navy Department 60Raytheon ARaytheon BCoast GuardArmyMarinesSure --I’ll be there!
16 The AnswerI hear theCOAST GUARDhas a good team!!
17 An “expert” lipreader is guessing at 66% of what is said! Did You Know?Lipreading is only successfulwhen the speaker never movesall the words are knownthe words are predictableOnly 1/3 of speech is visible on the lipsAn “expert” lipreader is guessing at 66% of what is said!
18 How Does Lipreading Work? How air is stopped (teeth, lips, none)“s”“f”Inside the mouthThroatVocal Chords“s” versus “f”same except for the highest frequencysound the same with a high frequency lossthey look different on the lips
19 How about if you sit closer? We can turn up the volume…
20 Louder Not Necessarily Clearer What is this word?
21 Louder Not Necessarily Clearer Now it’s louder…
22 Louder Not Necessarily Clearer Now it’s clearer.
23 Ambiguity is the Real Problem A few numbers that sound the same15, 16, 50, 60“Fifteen, that is, one-five.”Letters sound the sameB, C, D, E, G, P, T, V, Z“C as in Cat”Try it again, I got part of itSometimes I need you to use a different word
24 Filling in the Gaps Hard of Hearing People Play “fill in the gaps” to guess at the missing notesACOPSU N DE R __ T A N D
25 In noise there are more gaps to fill. Losing the RaceIn noise there are more gaps to fill.U DE R __ T A DNNAOCSP
26 Competing Speech Is Worst With nearby conversations there are gaps to fill and errors to correctU Q DE R __ T A R DAOCSP
27 Time Delay to Fill in the Gaps When the next phrase arrives before sorting out the previous one, it becomes too hard to keep up.People with hearing lossneed extra processing time to listen.
28 Very Little Usable Volume Can you turn it up, I can’t understand the programCan you turn it down, I can’t think over here.OuchPerfectVolume = 3Volume = 5Volume = 8
29 A Common Phenomenon for Hard of Hearing People Need “8” to understandNeed “3” to ignoreEverything in between is uselessSource of misunderstanding:“they have selective hearing”“this noise won’t bother them”
30 Confidence about Hearing Experience in guessing wrongNot confident about what was “heard”Examples:“Are they late, or did I get the arrangements wrong”“Yes, I’ll give her the message” “I didn’t understand them, you’ll have to call back”Not enough to say “did you understand”,Need to ask for information to be repeated back
31 “I Think I Hear Fine” Poor mitigation strategies Let me know if you miss anythingDid you hear everything okay?Same as asking: Are you asleep?Person with hearing loss is worst judge of what they heardMy biggest problem is not what I didn’t hear, but what I think I did hear
32 Communication is About Communication is not aboutwhat is saidhow it is saidCommunication is AboutWhat is Understood
33 My Hearing Loss Hearing loss is a challenge, not a limitation Hearing loss is something you share with everyone you attempt to communicate withAccommodation is a tool, not a weaponEars are not important – only what is in betweenWhat do you mean I can’t… Watch me.We can talk about my hearing loss.I want you to understand.
