Could you recap the difference between receptor potentials and action potentials?

2025-05-14 11:05:53 UTC

Can you give us a document with key concepts/lectures we NEED to know for the exam, as well as a more in-depth run through of what is to be expected in the exam types of questions (multiple choice, short answer etc, use of notes)

How are we meant to come up with a hypothesis for the DPOAE assignment?

2025-05-14 14:42:41 UTC

Just to be clear, DPOAE's can or cannot distinguish between conductive hearing loss and sensorineural hearing loss?

2025-05-14 14:43:07 UTC

is exam only on hearing portion of the unit or also perception?

2025-05-14 20:50:30 UTC

I'd just like to confirm that we are supposed to essentially 'make up' our own data for each of the participants as long as the respective 'peak' is included and that the data is justifiable...

2025-05-14 20:52:53 UTC

Many of the DPOAE graphs we looked at in class showed positive and negative peaks at the end points (highest and lowest kHz) making a sort of S-curve shape, so I am a bit confused with the peaks provided in the data from the tables being situated around 2-4 kHz which would be somewhere more central. I'd love some clarification as I'm not sure if I've got that all wrong.

2025-05-14 20:57:05 UTC

will there be any data analysis questions on the exam (eg. DPOAE graphs/ data to analyse) or will it mostly be based on the theory covering anatomy/ physiology of the auditory system and hearing?

2025-05-14 21:01:18 UTC

following the recap on action potentials, could we please go over hair cell transfer curves ?

2025-05-14 21:04:17 UTC

could we please revise the functions of the pinna, including: funneling, filtering and localisation? I also wanted to check whether localisation was a 'branch' of filtering or if is a separate function :)

2025-05-14 21:05:26 UTC

could we please go over how impedance matching works?

2025-05-15 00:25:59 UTC

Because we are applying our knowledge to kind of curate our report, do we need to reference the sources we use that help us with this like for the method when we discuss how the tool is calibrated, do we in text reference the source we used to help us write what we wrote? not sure if this makes sense

I was just wondering if I could get some extra clarification on the DPOAE report assignment as it is still quite confusing to me even after having read the FAQS. I understand that we are making up our method entirely based on similar existing literature, but how much of our hypothetical information would be too hypothetical. For example, I have seen research papers mentioning different pre-screening tools to assess the participant's ear prior to DPOAE data collection. It seems fitting to add these pre-screenings to the report as it would make it seem more realistic (and beacuse you mentioned that our method section required more detail than what was presented on the FAQ sheet), but they also seem too out of the scope of this assingment as we have not yet learnt about them so it is difficult to accurately apply them to this task.

Also, in the data table, were participant's hearing condition (normal/abnormal) deduced before or after testing for their DPOAEs?

And one last thing, is the overarching question we are trying to answer in this report how precise DPOAE assesments are at indicating/predicting hearing loss???

2025-05-21 00:53:36 UTC

Are we saying that the participants had normal hearing before testing? I'm just a bit confused because how can we say that if some show conductive or sensorineural hearing loss through the results. Also how did one of the participants have an earwax blockage if their ears were checked by an otoscope prior to the study?

2025-05-21 03:48:49 UTC

Hi Sarah!

I had a question on describing DPOAEs. How much in depth should we go when discussing DPOAE fundamentals? (primary, difference, summation tones etc).

Thank you!

2025-05-22 01:04:21 UTC

Just confirming that we are allowed to look at typed notes and readings on our devices for the final exam. I was caught out in a previous unit with an online exam because the instructions said that "written notes" were allowed and the invigilator told us not to look at digital notes. Thank you!

2025-05-22 02:32:48 UTC

could we please go through the pitch perception theories again?

2025-05-24 01:31:32 UTC

For participants with DPOAEs present in one ear but absent in the other, there is no peak frequency provided for the ear with present DPOAEs. Do we then make up a peak frequency? Or, do we just focus on the affected ear for that participant? Apologies if this has already been answered, I wasn't able to find anything addressing this.

2025-05-28 00:00:19 UTC

could we please go over the MOC Reflex again?

2025-05-28 01:32:26 UTC

with the peaks, are they referring to peak SNR values as opposed to amplitude values?

2025-05-28 09:21:35 UTC

Hi Sarah,

Just wondering if it is recommended to comment on pass/refer values and criteria in our reports? Or is this not necessary? Thank you!

2025-05-28 12:31:03 UTC

Hello Sarah,

This assignment is really confusing me and its really stressing me out. Regarding the results section, why are we needed to make up data? And do we need to present average or standard deviations for frequencies? or for DPOAEs?

2025-05-29 03:11:12 UTC

Just to clarify, are we not presenting the report as though we did the experiment? I have been writing mine as though I did the experiment and obtained specific results. As in, this is what I did, here's how the results were recorded, participant X had an average DPOAE of X dp SPL, etc. But it sounds like it was meant to be more of a hypothetical, here is how these studies are done?

Is it okay if we are doing it the former way?

2025-06-01 19:04:12 UTC

hello! the maximum word limit 2500, I was wondering what the minimum was? Is it 10% over or under as per usual? Thank you :)

2025-06-04 03:14:06 UTC

If we have any questions in the week leading up to the exam after week 13, are we able to email you for clarifications?
