NEW: Former Gallaudet Employee Speaks Out Against “Deceitful, Fanciful Thinking” in University’s Response to DoEd Layoffs
Disability Rights Watch (2025)
The Deaf and Gallaudet communities need to band together to (1) push the Gallaudet Board of Trustees and administration to acknowledge these facts and lobby—and sue, if necessary—for this restoration and reinstatement, and (2) write to senators and representatives to advocate.

This is pretty cool - reptile found that can sense low frequency sound with the saccule: https://doi.org/10.1016/j.cub.2024.09.016
(I'll edit with a direct PDF link in a sec)
Hearing evolved in fishes, where the swim bladder as a big resonant cavity reached out to touch the vestibular organ and kinda vibrate it. That is only good for low frequencies, so to some degree the history of the evolution of audition has been a quest for higher frequencies - thinning out a tympanic membrane, the evolution of the inner ear by stealing jawbones, the enlargement of the brain case to close off the middle ears (our eustachian tubes are vestigial remnants of what used to be an "open passageway" from ear to ear).
Sound is a veridical readout of the matter that produces it, so different frequency ranges contain different kinds of information, and small things including textures and material composition are only audible with higher frequency ranges. Low freqs are important too, but especially with the transition to land, needing to handle the impedance mismatch between fluid filled bodies and open air makes an organ that can hear a wide range of frequencies challenging.
So the cochlea gets all the attention as the auditory organ because its one of the most remarkably precise and Scientifically Magical organs out there, but the vestibular system is cool too. It's basically a bag of saltwater and rocks and when you jangle your head around the rocks touch little hair cells and tell you you're moving.
Because of its torrid history the auditory system is sort of a clusterfuck, but these researchers found direct projections from the Saccule through to the auditory midbrain. They're sensitive to vibration (through a surface), not sound (through the air), but still go to auditory system, so while we have no idea what the perceptual reality is like, i dont think it is unfair to say that the geckos "hear vibration."

Amplitude fluctuations in a masker influence lexical segmentation in cochlear implant users
Perry and Kwon, 2015
"CI listeners showing little or no masking release are not reliably segregating speech from competing sounds, further suggesting that one challenge faced by CI users listening in noisy environments is a reduction of reliable segmentation cues."
PubMed Central (PMC)Amplitude fluctuations in a masker influence lexical segmentation in cochlear implant usersNormal-hearing listeners show masking release, or better speech understanding in a fluctuating-amplitude masker than in a steady-amplitude masker, but most cochlear implant (CI) users consistently show little or no masking release even in artificial conditions ...
Neural encoding of linguistic speech cues is unaffected by cognitive decline, but decreases with increasing hearing impairment
Bolt & Giroud, 2024, Sci. Reports
"These results suggest that while speech processing markers remain unaffected by cognitive decline and hearing loss per se, neural encoding of word-level segmented speech features in older adults is affected by hearing loss but not by cognitive decline."
NatureNeural encoding of linguistic speech cues is unaffected by cognitive decline, but decreases with increasing hearing impairment - Scientific ReportsThe multivariate temporal response function (mTRF) is an effective tool for investigating the neural encoding of acoustic and complex linguistic features in natural continuous speech. In this study, we investigated how neural representations of speech features derived from natural stimuli are related to early signs of cognitive decline in older adults, taking into account the effects of hearing. Participants without ( $$n = 25$$ ) and with ( $$n = 19$$ ) early signs of cognitive decline listened to an audiobook while their electroencephalography responses were recorded. Using the mTRF framework, we modeled the relationship between speech input and neural response via different acoustic, segmented and linguistic encoding models and examined the response functions in terms of encoding accuracy, signal power, peak amplitudes and latencies. Our results showed no significant effect of cognitive decline or hearing ability on the neural encoding of acoustic and linguistic speech features. However, we found a significant interaction between hearing ability and the word-level segmentation model, suggesting that hearing impairment specifically affects encoding accuracy for this model, while other features were not affected by hearing ability. These results suggest that while speech processing markers remain unaffected by cognitive decline and hearing loss per se, neural encoding of word-level segmented speech features in older adults is affected by hearing loss but not by cognitive decline. This study emphasises the effectiveness of mTRF analysis in studying the neural encoding of speech and argues for an extension of research to investigate its clinical impact on hearing loss and cognition.

Audiograms and Prevalence of Hearing Loss in U.S. Children and Adolescents 6–19 Years of Age
L Humes 2024, JSLHR
"For children and adolescents in the United States, hearing was unaffected by differences in sex and race/ethnicity, with only age impacting pure-tone thresholds and only at the lowest (500 Hz) and highest (8000 Hz) frequencies examined. The overall prevalence of hearing loss was about 11%."
Replied in thread
@erictopol Eh, this is not particularly persuasive on it's own:
"Secondly, due to data restrictions, this study did not include audiological data such as pure tone thresholds or speech audiometry of the diagnosed patients."
I don't put a great deal of trust into studies that rely on restrospective analysis of diagnostic codes.
