Masking in Clinical Audiometric Testing: A Tutorial

[@zoehector1389]

This is fantastic! A brilliantly clear (and fun) explanation of a gnarly topic. Yours sincerely, a very fresh (and confused) Audiology student...

[@PaceBarkdoll]

how did school go?

[@zoehector1389]

@@PaceBarkdollgraduated with distinction long ago ;) Recommend this video to my students!

[@iasminferreira1200]

i'm a student who wants to be an audiologist, thank you so much!!!! for this video you are really helping and inspiring me to love more this profession

[@treeoftears]

This explains why some audiologists have told me I have some hearing in my right her whilst others tell me I have none. An audiologist tried to explain to me that the other audiologists had not done proper testing and that what they thought was me hearing in my right ear was actually just conduction to my left ear.

I love the student's excitement to getting the plateau. It makes me miss doing audios.

[@alexapolitis8244]

This is the best video! I'm watching it to study for my final . Thank you!

[@FlapFlapOctopus]

Thank you! I'm starting my first external placement in about a week and this is a great refresher!

[@AudiologyStudents]

Amanda, this is just terrific. I hope you don't mind, I'm assigning it as a home supplement to my undergrad students to review, because you do a great job of explaining in a way that supports my mantra in class that Masking Is Fun. :)

[@mandy123453]

I love that! Masking is Fun indeed!! Thank you so much for the positive feedback. I should have captions on the video this weekend.

hi amanda i am going for hearing aid dispensing and i recently took the written exam and failed. one of the main things that killed me were case study questions i.e how you would fit based off of an indivisual needs binaural vs monoaural cros bicros different diseases affecting different wrs srt scores and what hearing aid is appropriate for each loss range was wondering if you can make a video on how to properly do a case study and break it down? i would appreciate it! or at least send a link where i can learn from a website that shows how to break one down? thanks amanda!

[@AkashSharma-mf5yo]

Hey! Can you explain what IA should be taken during masking because in Katz the IA should be the difference between the Air conduction threshold of right and left ear Please explain

[@renehornby4262]

Dear Dr Ortmann. I have been using this masking formula successful in private practise during 2014 especially the initial masking level. I would like to teach this method to local students but I require a reference/publication as needed in any university setting? Could you please assist me so that more audiologists South Africa can apply this method.

[@robertacree321]

Thanks for that entertaining and well presented masking tutorial!

[@laurenmarie3897]

You’re awesome!!! Will you be making anymore videos??

[@maddiedebernardi3457]

Wish I could have you as my proff! Great video, really helped me out. I would love if you made another video using insert headphones

[@d.perera7875]

Hi Dr. Ortmann, Why does she mean in 20.09 as 'they are already occluded'?

[@sweekritishetty322]

Mam...why don't you continue teaching concepts in this way....its really very much fun learning this way please upload more and more videos

[@Jess_7788]

You are so good at teaching, thank you so much for this video!

[@8dreamer1]

Thank you so much. The ways you reviewed masking really helped me understand the concept. Could you make a video explaining the plateau method a little bit more?

[@mandy123453]

Hi Maryann, I'm glad that the video helped you. That is the true goal of the video series. I'll consider making a brief video on the plateau method so that the concept is solidified. I think you'll find however that the more you execute this method in clinical testing, but more it makes sense. As you continue your AuD career, refer back to the video a couple of times and the pieces will come together. Good luck!

[@8dreamer1]

Thank you for taking your time to respond. I am barely beginning y AuD career, so I think you are right. I just need to practice a lot! And I will refer to them :)

[@ashermrufus9376]

Awesome... good presentation and well explained

[@marius72za]

Very good Video!!!!!

[@katherineploumidou6387]

Very good explanation in masking !!!!

[@xrctyvuhbjn]

wait so If the unmasked bone conduction of left ear is normal for example, but the unmasked air-conduction for the right ear shows a moderate CHL and the difference was 40dB and they're wearing inter-aural headphones, would you mask bone conduction for the right ear?

[@modiulelawson9790]

What if you didnt hear the 1.2.3 louder in one ear when you blocked your ears?

[@justinpowell6689]

Hi Dr. Ortmann, Thank you for this great video. I am an AuD student and masking was taught to us in a more complex way; your method is more simplified. Do you by chance have a citation or literature reference for your masking method? Thank you!!

[@maanoasi]

Excellent tutorial thank you so much I finally understand masking :)

[@christineng4535]

Nice video Amanda! I have a few questions about the speech-in-noise test. Is it the same as a word recognition test, except that you add in background noise? But how do you decide the level of background noise? And is the noise available to both ears or just the test ear? Lastly, do you still need masking in that case? It will be great if you can help:) I can't find any proper explanation online...

[@priyankakundukulamparamba5806]

excellent tutorial.. thankyou so much

[@visionofthesoul]

Nice video..hats offfff Can you tell me about carharts notch in otosclerosis.. It's confusing me... Please

[@mandy123453]

Great question. This video doesn't address that question due to lack of time and it's focus on masking. First understand two things independently, then put them together. 1. Bone conduction (BC) testing: there are several factors that contribute to BC responses. For simplicity's sake, it is commonly stated that BC represents the inner ear (cochlea) response without minimal influence from the outer and middle ear. However, there IS an influence from the middle ear ossicles on BC results. When you vibrate the mastoid, it causes compressions and expansions of the cochlear shell, in turn causing displacement of the basilar membrane and inner ear fluid. However it is important to note what rests against the cochlea on the other side of the oval window. . . the stapes. Therefore compression/expansion characteristics of the cochlea via BC testing is dependent on the inertia (resistance to movement) of the ossicular chain. It is difficult to move one (cochlear oval window due to compression/expansion of the cochlea) without the other (stapes). In response to vibratory stimulation, the ossicular chain has a resonant frequency (maximum movement of stapes) around 2000 Hz in humans. 2. Otosclerosis causes stapes fixation which will alter the mass/stiffness of the chain and change the inertia component and resonance of the ossicles. Put the two together: in cases of otosclerosis and other middle ear disorders involving the ossicles, the bone conduction threshold will be more affected at the point where the ossicular chain contributes maximally to the BC response (at it's resonance) which is around 2 kHz. The elevated bone conduction threshold at 2 kHz is traditionally referred to as the Carhart's Notch. This can be reversible via otosurgery to repair the ossicles. It's a quick answer, but I hope it helps . . . I apologize for any errors in typing or omission of details. I am typing this up in between things at work.

[@visionofthesoul]

Thankyou... It helped me

Hi Amanda. I would very much like to watch this video. Unfortunately, the subtitles are not making any sense. Do you by any chance have a transcript. Thanks. Dee

[@mandy123453]

Yes of course. I will look into assigning my text to the you tube video so that it is captioned properly, so that it can be accessed by all. Give me a few days. If you want the text sooner, send me a private message with your email and I will be happy to send it.

[@deedavies2269]

Amanda Ortmann Thanks so much. I will send you a PM

[@deedavies2269]

Dee Davies Hi again. I can't seem to send you a pm on here. I'll wait for you to assign the text to the next U tube video. Thanks. Dee

[@mandy123453]

Dee Davies I'm going to put the captions on this weekend. So check it out on Sunday night. Cheers!

Thank so much ❤️❤️❤️

[@nickn8302]

That intro was insane, like, why the lazar vision cats?

[@mandy123453]

Nick, why not? Glad you caught that--I thought it was funny. And when I finish showing this video to students, I ask them, "Did you see the cat shooting lasers?" The ones who say yes are instantly my friends.

[@nickn8302]

Amanda Ortmann Sometimes insane is good, and in this case, it is! I'm going through the process of changing my major from Psychology to Communication Sciences and Disorders. I've grown to appreciate anatomy and physiology and Audiology looks like a great avenue to turn to, and it isn't too far from Psych either. I've been watching countless youtube videos and reading articles to get a sense of what I'm getting myself into, and this helps a lot.
