Objective: The authors investigated the relationship between behavioral and physiologic estimates of cochlear compression.
Design: Cochlear compression was estimated in distortion product otoacoustic emission (DPOAE) fine structure minima and maxima near 4 kHz. The composite DPOAE response and separated generator and reflection components yielded three estimates in four young adults with normal hearing. DPOAE estimates were compared to behavioral compression estimates derived using a growth of forward masking (GOFM) paradigm. The DPOAE primary tone f2 and GOFM signal were identical and selected individually based on placement in a DPOAE fine structure minimum.
Results: Across participants, DPOAE compression estimates derived from the generator component were most similar to estimates derived from the GOFM paradigm and did not vary with DPOAE fine structure.
Conclusions: These results suggest that the generator component may provide a quick, reliable estimate of cochlear compression in humans. This may prove useful in populations that cannot give behavioral responses.

Unlabelled: The article is devoted to the problem of the rehabilitation stage of cochlear implantation in patients with inner ear abnormalities. It provides a detailed analysis of the audiological characteristics of such patients and draws conclusions about approaches to interpreting diagnostic data and speech processors fitting.
Material And Methods: The track records of 80 patients with abnormalities of the inner ear development were retrospectively studied, of which 10 had abnormal structure of the auditory nerve.

Introduction: This report describes the outcomes of sensorineural hearing loss (SNHL) due to cochlear inner ear barotrauma (IEBt) in five divers treated with hyperbaric oxygen (HBOT).
Methods: The case histories of five consecutive divers presenting with SNHL from IEBt due to diving, were reviewed. All divers provided written consent for their data to be included in the study.

The bony labyrinth of the inner ear houses the sensory end-organs responsible for balance (otolithic system in the utricle and saccule, and semicircular canal system) and hearing (cochlea). Study of the bony labyrinth has revealed considerable morphological diversity in the hominin lineage (semicircular canals and cochleae) and aided in reconstructing essential aspects of primate evolution, including positional behavior, audition, and phylogenic affinities. However, evidence of evolutionary change in the hominin otolithic system remains elusive.

To compare the vibrational patterns of human and guinea pig cochleae accurately, we developed and validated a novel finite element model of the guinea pig, leveraging it to analyze vibrational patterns in the cochlea. This approach is mirrored in our examination of the human cochlear model, providing granular insights into the nuances of human bone conduction hearing. The comparative analysis reveals that the guinea pig cochlea mirrors human cochlear vibrational patterns, thus serving as an efficient proxy for exploring human cochlear function.

Purpose: The goal of this research was to record sound-evoked vibrations in the organ of Corti at the apex of the intact cochlea of the chinchilla, an animal with a frequency hearing range similar to that of humans.
Methods: Twelve adult anesthetized chinchillas of either sex were used. Measurements of sound-evoked vibrations of the intact organ of Corti (OoC) were performed using optical coherence tomography (OCT).
