🎯 Key Takeaways for quick navigation:
00:04 🔊 *ABR, or Auditory Brainstem Response, is a brain stem-generated potential in response to auditory stimuli.*
00:30 📉 *ABR focuses on waves 1 to 5, with wave 5 being the primary focus for threshold testing due to its size.*
01:14 🌊 *ABR morphology varies widely in clinical practice, making interpretation challenging.*
02:11 📏 *Key factors in determining ABR response include morphology, latency, and amplitude.*
04:01 ⚖️ *ABR amplitude and latency change with intensity levels, aiding in response identification.*
07:24 📊 *Additional tools like FMP and residual noise calculation assist in assessing ABR presence and waveform quality.*

Very informative thanks
what is a BAER Ultrasound for?
hello dr. shane. how many decibels are the max. applied in BAER? I got 90decibels last week in that test. my tinnitus spiked after that. is there a possibility to bring back to normal base? thanks
Hi Rico,
The maximum stimulation levels available vary depending on stimulus, frequency, transducer and device used. If your tinnitus seems worse following the test, then I recommend you speak with the clinician who performed the test for further advice.
Best regards,
Shane
thank you dr. shane. do you think that 90db damaged my ear esp. the hair cells. you're response on this will be highly appreciated.
Hi @@ricocajudo8806,
Please reach out to your clinician regarding the treatment you've received.
Best regards,
Shane
good morning sir...
why does a conductive hearing loss causes for wave v latency to be prolonged/ longer..
thanks...
Hi Francis,
Conductive hearing losses can lead to longer latencies due to energy loss that occurs as the stimulus progresses through the dysfunctional middle ear. This can lead to an attenuation of the stimulus once it reaches the cochlea, resulting in longer latencies.
Best regards,
Shane
@@InteracousticsTV thanks shane..
hello dr shane..
is conductive hearing loss the only reason that can causes the wave v latency to be longer than normal...?
thanks..
Hi Francis,
No, various types of hearing losses, or neurological issues affecting the auditory nerve pathway, can also lead to longer wave V latencies. And conductive losses don’t always show up with longer wave V latencies.
Best regards,
Shane
so if that is the case... what is a good test to define presence/ absence of conductive hearing loss with the abr...? dr shane... thanks..
@@francisadajar9617 Hi Francis,
Tympanometry can provide an assessment of the middle ear function, however to confirm whether a hearing loss detected via ABR is conductive, mixed or sensorineural, bone conduction ABR testing is essential.

Best regards,

good morning dr shanes...
can a conductive hearing loss cause for a severe/ profound degree in the abr test...??
thanks..
Hi @@francisadajar9617,
Typically, one would not expect a conductive hearing loss alone to present with severe to profound levels.
Best regards,
Shane
Plze sir I have my little baby girl has problem with hearing so I did test, so what should I do
Hi Dr. Abdinasir,
Sorry to hear about your daughter.
Without knowing your exact circumstances, you need to reach out to your local physician / audiologist or similar to find out the best options for hearing rehabilitation.
Hope you'll be able to find treatment for your daughter.
Best regards,
Shane
@@InteracousticsTV thank you , my country does't have any Audiologist and I can not go outside because I don't. Have that much money , I am from Somalia , plze help
@@dr.abdinasir7274 Hi there, I tried searching for it online and found this location: www.phonakpro.com/com/en/about-phonak/locations/s/Somalia.html
It was the only I could find in Somalia.
Best,
Shane
I have same problem that is been occurred when I was on duty, an according to ENT specialist confirm that is coursed by Acoustic trauma, but the company still trying to avoid me, and all Audiograms shows that it was normal before it still shows.
Please people just help I'm really suffering with my disability ear 16% hearing loss and 8.1% permanent loss
Kind
Regards
do you have an actual copy of your audiogram? there is no use in saying u have 16% hearing loss or 8.1% permanent loss when we cannot see what that actually looks like.
I have a test result can u please explain. Dr is not expert here.
Kindly show me the results of your abr tests...
