Bull, am a retired marine, now a paramedic, as a private security contractor, going through A&P I....kuddos to you, keep it up! Have wached most of your stuff, easily palatable!
OK... here we go, part 2! Thank you again. Your videos are most helpful. My professors are super energetic and knowledgeable this semester but it really helps to view your lectures before I go to class. I get a better understanding and I am prepared to ask questions. I find the ear particularly fascinating! Good thing I am going into speech pathology LOL
Be careful using Q-tips. As an Aud. student, I've seen many patients who developed hearing loss not from damaging their tympanic membrane, but from narrowing of the ear canal due to the q-tips pushing the ear wax deeper and building up a clog. Most people have an s shaped ear canal, so it's quite difficult to damage your ear drum unless you don't feel pain. the deeper portions of the ear canal are very painful if poked because it's basically a thin layer of skin on bone. GREAT VIDEO THOUGH, VERY INFORMATIVE.
The way I understand it you're not supposed to clean your ears because the ears can handle themselves. The wax is there for a purpose and should not be removed by q-tips, which are more likely to push the ear wax in and put pressure on the timpanic membrane than get it out. Q-tips should only be used to clean the external ear.
I decided to do this lecture just for fun and was very glad that I chose yours! Love it! I'm looking forward to learning more when I have some free time to listen to another lecture, keep it up!
Doing preemptive studying to obtain a position as a hearing aid specialist. Thank you for making this video easy to follow for people who have been out of school for a few years. Digestible, but meaty!
Your video was clear, concise and very helpful for a first time learner. I watched your video after reading my course material and reviewing my notes. This summed everything up for me nicely. Thanks a lot.
Thank you so much for creating this video. I am eager to commence my postgraduate studies in clinical audiology next year, and this has been a very useful introduction to the structure/function of the ear. Cheers from Australia!
Sorry for my bad English. A very good lecture, but you've mixed up 2 things. 1. Nobody should use p-tips in the ear. The ear is self cleaning. Ear wax is necessary. Your forcing it back, blocking sound, irritating the skin, getting eczema. Use toiletpaper and remove the visible wax. 2. you are mixing up frequency (pitch) and amplitude (volume). You are not damaging you hair cells by listening to high frequency sounds, but you will if the sound is to loud no matter what the frequency is.
Thynk you for your video I would like to remark, that you mix the sens of amplitude and the frequenzy. I whould like to ask, to be mor specific in this point. I think, the Amplitude ist the reason of the force of an acoustic wave. Lets say the volume. On the other hand, the frequency is the reason of the sound we will hear. In fact, high frequency for high sounds (like a mice it does) and low frequencys for low sounds (like a roaring of a bear). Thank you anyway for this great work
@cents454 I use the SMART board, it's basically an electronic white board. I agree with you, it's a fascinating piece of equipment that has really helped me reach out to a lot of people and is far superior to the crappy webcam on my computer I was using before to video myself standing in front of a board and talking.
This is the best video I have ever seen. Thank you so very much for this free education!!! I just have one thing. I know out ears are more sensitive to high frequency sound. However lower frequency sounds I know take much more energy to produce, and move our tympanic membrane much more. Wouldn't lower frequency, higher pressure sound be more likely to damage our ears than high frequency sounds? I would love to hear a reply. This is how I learn. Again thank you for this excellent video!
A few comments above mention how he talks about frequency as loudness. My understanding is that frequency is pitch, not loudness. Intensity is loudness.
Awesome video dude! Im a speech and hearing sciences major and this helped me so much with my hearing science class! Its such a hard subject! You are wayyy better than my teacher! love all the pics! Great Job! This helped me out alot! Thanks so much!
Agreed. I'm in school for Audiology and we are told countless times: "Do NOT clean your ears." Not because we are stupid and will stab our tympanic membrane. We are told so because ear wax needs to be in our ear. When you put a cue tip in your ear, you're pushing your ear wax further in; which will cause issues. Then you have to make an appointment to see me and I get to remove ear wax a few mm from your ear drum. It does not feel good. It's an uncomfortable procedure. So, don't clean your ears.
@charliegraceable Awesome, I'm glad this helped you out! Thanks for your support and good luck with your exams. I can't think of anything else ear related at the moment I have time for, I will be doing the brain and eyes soon.
Hi! i loved your video! Great preview to what I'll be be reading in the next few days. I was fascinated by the use of your onboard marker, and basically your entire setup to teach this class. what sort of tech did you use here..? electronic tablet..? would love to know! Thank You!
@toasterder I appreciate your input and am well aware of the fact that hearing loss is more complicated than what I mentioned in the video. I was simply stating something simple that went with the lecture and also bear in mind this video was not meant for students who are going that in depth. This is a video for either first time learners or for people to brush up on some basic knowledge. Here is a good article relating to the topic you mentioned
good vid but i think there was an innacuracy describing loud noises. the waves amplitude is larger for loud noises, not frequency. variations in frequency are what is responsible for differing pitches (as described at the end).
I am sure, by now you have realized that high frequency does not mean high energy and visa Versa - so, don't you think you should edit this lecture to correct this important error. Energy relates to the amplitude of the sound wave ( volume/ intensity). The frequency relates to the number of displacements per unit time and the volume relates to the hight of the waves- more energy.Otherwise great lecture ..
hi, thanks so much for this great video. It was really helpfull. I will definately be seeing a lot more of your videos from now on. When will the one about the anatomy of the eye be available? Thanks again.
@CieLoMeLBouRNe I'm glad you liked the video and found it helpful! That's just something I have been wanting to say for a while and I figured this was a good place to get it out
Hi the lecture was good, thank you very much for it. Just one thing though, you know the part on the Cochlea and Basilar Membrane, it felt like it was rushed, and you were just naming the parts, either that or i'm slow :)
As an audiometric technician, we recommend that our patient NOT use Q-Tips because they push cerumen(earwax) deeper into the canal, and over a period of months or years the earwax becomes impacted(restricts/blocks) with wax. This will usually cause people with normal hearing to feel as though they have a hearing loss(and cause people with present hearing loss to be exacerbated) because there can be sound intensity issues and sound quality issues, especially among the elderly. So, I stand by NOT using a Q-Tip for this simple reason.
Good lecture.but next time be more specific like those professional lecture.read and define everything in one go.would make your lectures small and time saving
Just a warning... this guy's understanding of high vs. low frequency sounds and how/why they affect different parts of the basilar membrane is pretty fundamentally flawed. Frequency = pitch, not loudness. The basilar membrane is stiffest at its base, which accounts for its response to higher frequency sound (due to resonance). Definitely review other lectures if you are studying that concept in particular.
Ear wax is a very important aspect of immunity which defends your body against foreign pathogens. The ear wax has several different substances like IgA immunoglobulins that provides your body with adaptive immunity. It also has lysozymes and other enzymes which degrade pathogenic bacteria/viri by degrading theyre membranes. No one has excess ear wax. If you do, which is a rarity in itself, then you have a disease known as sebborrhea. You should NEVER clean your ears.
