🎯 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.* Made with HARPA AI
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
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.
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
@@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.

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
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
