[Research Progress of Chirp ABR and Its Application in Forensic Auditory Identification].

The objective assessment of hearing loss is one of the critical components in forensic clinical research. Auditory brainstem response (ABR) is an important method for objectively assessing hearing levels. It is divided into various types based on different stimulus signals, each with its own characteristics and applications. Among them, narrow-band Chirp ABR, due to its frequency specificity, fulfills the basic requirements for objective assessment of forensic audiology, promising to be an important method of objective hearing assessment in forensic medicine. This article reviews the development history, characteristics and clinical applications of Chirp ABR, and envisions its application prospects in forensic auditory identification.
