A recent paper by Assistant Professor Dr. Akshay Maggu and Research Assistant Carly Furlong, B.A., SLHS ’25, in Hearing Research introduces a novel electrophysiological protocol using a 4 kHz chirp stimulus that enhances Auditory Brainstem Response (ABR) Wave I amplitude and reliability—promising for detecting subtle auditory-neural dysfunctions.

 

Their study, “ABR Wave I is Enhanced with 4 kHz Chirp Compared to Traditional Broadband Click,” demonstrates that a high-frequency 4 kHz chirp stimulus elicits stronger and more reliable ABR Wave I responses than traditional clicks. This work highlights the development of a novel electrophysiological protocol that could improve clinical detection of hidden hearing loss and subtle auditory-neural deficits.
