Envelope Following and Otoacoustic Emission Responses for Hearing Assessment

This dataset contains envelope following response (EFR) and distortion-product otoacoustic emission (DPOAE) recordings from normal-hearing and hearing-impaired listeners. It includes physiological measurements of auditory system responses to stimuli at frequencies of 0.5, 1, 2, and 4 kHz. The data was collected to investigate the use of EFRs for estimating peripheral level compression in the auditory system.

Use Cases

• Modeling peripheral auditory compression based on EFR magnitude and stimulation level.
• Comparing auditory physiology between normal-hearing and hearing-impaired groups using subject-level data.
• Analyzing signal-to-noise ratios in electrophysiological recordings using background noise floor estimates.
• Validating significance criteria for DPOAE measurements across multiple frequencies.

Strengths

• Includes data from two distinct listener groups: normal-hearing and hearing-impaired, enabling comparative analysis.
• Provides repeated measurements for the normal-hearing group, allowing for assessment of test-retest reliability.
• Contains multiple measurement types (EFR and DPOAE) for the same subjects, offering a multi-faceted view of auditory function.

Limitations

• Key metadata such as row count, file size, and specific update dates are not provided across all sources.
• The dataset description references DPOAE data not included in the final manuscript, potentially indicating incomplete documentation.
• The exact number of subjects and recording sessions is unspecified, limiting precise assessment of dataset scale.
