Unlabelled: Brainstem Evoked Response Audiometry (BERA) is an objective and non-invasive method of hearing assessment which detects electrical activity from the inner ear to the inferior colliculus.
Aim: To assess the hearing pathway in normal hearing individuals and compare differences associated with gender, age and ear side (left and right).
Study Design: A retrospective study.
Materials And Methods: Sixty normal hearing individuals, aged between 09 and 66 years old, were subjected to clinical ENT examination and audiologic tests.
Results: Wave latencies differed significantly between males and females, although there were no differences regarding right or left ear sides. Comparing latency averages regarding age and gender we noticed important differences. By the same token, significant differences were also seen comparing this study with the information present in the handbook of the BERA device used and results published by Fukuda, in another study.
Conclusion: Knowing the great importance of BERA, it is crucial that each service develops its own standards in order to enhance the accuracy of the electrophysiological diagnosis of the hearing pathway.

The objective of this study is to assess the potential of a transformer-based deep learning approach applied to event-related brain potentials (ERPs) derived from electroencephalographic (EEG) data. Traditional methods involve averaging the EEG signal of multiple trials to extract valuable neural signals from the high noise content of EEG data. However, this averaging technique may conceal relevant information.

The constant need to listen attentively leads to heightened frustration, fatigue and decreased concentration. According to research, high-frequency hearing loss could have negative implications on speech perception and make it even harder to communicate.

Hearing loss has historically been mainly associated with elevated pure-tone thresholds. However, in recent years, there has been increased interest in addressing the hearing difficulties reported by individuals with normal hearing thresholds. In this study, we measured hearing thresholds, noise history, temporary threshold shift history, and hearing difficulty for a sample of 10,492 Service Members.

Purpose: Tympanoplasty is a surgical procedure performed to cure middle ear infections and restore normal middle ear function. It is one of the most common procedures in otological surgery. Since Wullstein described tympanoplasty, the microscope has been a widely used surgical tool in otological surgery.

Hearing aids (HAs) have been used for standard high-frequency hearing loss and tinnitus, but their effects on speech intelligibility in noise (SIN) in people with normal hearing, including hidden hearing loss (HHL), have been little explored. We included in a prospective cohort study patients who experience poor SIN and have normal pure tone average in quiet conditions or slight HL. We used open-fit HAs.
