What is Auditory Brainstem Response (ABR) Testing?

This video provides an overview of the basic theory of threshold auditory brainstem response (ABR) testing, with a focus on testing the newborn baby population.

This video is taken from the Interacoustics Academy online audiology course "Getting started: Threshold ABR".

🎯 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.*

good morning sir...

why does a conductive hearing loss causes for wave v latency to be prolonged/ longer..

thanks...

[francisadajar]

hello dr shane..

is conductive hearing loss the only reason that can causes the wave v latency to be longer than normal...?

thanks..

[ricocajudo]

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

[kennethmaaba]

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

Plze sir I have my little baby girl has problem with hearing so I did test, so what should I do

[ghulammujtaba]

I have a test result can u please explain. Dr is not expert here.
