Abstract

fetched live from OpenAlex

When an individual speaks, laryngeal vocalizations are generated in the ear canal. Normally, these vibrations escape from the external auditory meatus. When the ear canal is blocked by an earmold or hearing aid shell, these vibrations translate into increased low frequency SPL reaching the tympanic membrane. This bone-conducted phenomenon is called the occlusion effect. Hearing aid users also may experience altered perception of their voices due to air conduction of the sound amplified by the hearing instrument. Because this second phenomenon is related to amplification it is termed ampclusion. The origin of the problems can be determined through a systematic approach. Once determined, the effects can be relieved via changes in otoplastics, electroacoustics, and/or counseling. KEYWORDS Occlusion - ampclusion - bone conduction - otoplastics - electroacoustics

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
