Abstract

The number of people with hearing loss is a growing concern, and early intervention is essential. It is possible to address this scenario using Auditory Steady-State Response (ASSR) as an objective technique to assess auditory thresholds. With the aim of improving ASSR detection, it is possible to adjust the auditory stimulus to amplify the response. Therefore, it is pertinent to compare the performance of different stimuli. This study aims to compare the performance of NB-Chirp and AM2 stimuli in evoking ASSR, analyzing the detection rate and the distribution of detection rate probabilities for different electrode combinations. The results indicate that the NB-Chirp stimulus yields a higher number of electrode combinations with detection rates superior to AM2, demonstrating a statistical difference between the detection rate probability distributions.
