Thanks for posting. Your explanation was very helpful and at a nice level to begin to understand the concept.
Thank you. That was very informative and easy to understand
great explanation really helped me a lot to make basics
This really helps. I understand this much better than before!
Awesome, glad to hear it Margo :)
Best regards,
Shane
Very detailed and informative
Thank you
Спасибо за помощь, все очень подробно изложено и полезно в практике аудиолога
thanks for sharing this lecture, but the sound level is barely hearable .. hopefully you solve this problem
I have remastered the audio for this video, and re-uploaded it here: th-cam.com/video/AhTbfEZue_k/w-d-xo.html
Sir, In ABR graph report, wave V is showing downwards near normal shaded area means wave v located downward of normal shaded area..Wave V:-80 Li is 3.82 ms, 70Li is 4.92ms and 60Li is 3.60 ms and other waves are absent..Sir,what is meaning that sir??
O audio está extremamente baixo, dificultou a compreensão do conteúdo. Apresentação muito boa.
Hello sir.., can the abr be used to know the type of hearing loss..? If its conductive loss or sensorineural h loss.. for infants case.. thanks.
Hi Francis!
Yes, ABR testing can be used to identify the nature of hearing loss in people of all ages, including infants. Bone conduction testing is required to establish whether the hearing loss is conductive, sensorineural or mixed.
Best regards,

Thanks a lot for posting this webinar! It really helped me to understand ABR in a simple way
Did you also have a video with a focus on using ABR to measure the neurological function of the brainstem?
I couldn't find one Jenna (sorry!).
We have a short written description on our website: www.interacoustics.com/guides/test/abr-tests/neuro-latency-testing
Best,
Shane
@@InteracousticsTV Thanks!
Can you explain about temporary protocol set up?
Thank you for your interest. In the Eclipse the temporary protocol is a method of making quick changes to the test parameters for a single test only. It is accessed by pressing the "set up" button next to the protocol drop drown box. Inside the temporary settings you are able to change the stimulus settings , filters, recording properties, and display properties. Please note these are only saved temporarily, and if you require a permanent change then you should change the protocol in the system setup.
Tq so much
You're welcome Sanjay!
Do hearing aid specialist perform ARB’s or just audiologist?
Hi!
This depends on the country that you are in and the relations set by that country. Typically we see ABR most commonly performed by audiologists worldwide.
Best,
Shane
Need to fix the audio
Hello. Thank you for your interest. Please check the remastered version of this video for better audio. You can find it here: th-cam.com/video/AhTbfEZue_k/w-d-xo.html
Your audio voice quality is very poor not audible clearly
Hello Bharath. Thank you for your interest. I have remastered the audio for this video, and re-uploaded it here: th-cam.com/video/AhTbfEZue_k/w-d-xo.html I hope this makes it much easier to hear :)
Very bad audio
Thank you for your interest. I have remastered the audio for this video, and re-uploaded the new version here: th-cam.com/video/AhTbfEZue_k/w-d-xo.html
