Could the hormonal changes associated with menopause affect a woman’s ability to process auditory information?
Trott et al (2019) compared performance on tests of central auditory function between 14 pre-menopausal women (mean age = 30 years) and 14 peri- or post-menopausal women (mean age = 54 years). All subject had pure-tone hearing thresholds of 25 dB HL or better at 500, 1000, 2000, and 4000 Hz in both of the ears.
Subjects completed the following behavioral central auditory processing (CAP) tests: the Dichotic Digits Test (Musiek, 1983), the Duration Patterns Test (Musiek et al, 1990), the Listening in Spatialized Noise Test – Sentences (LiSN-S) test (Cameron and Dillon, 2007), and the Speech Perception in Noise—Revised Test (Bilger et al, 1984). Trott and colleagues also collected auditory brainstem response (ABR) and middle-latency-response (MLR) measures on these subjects.
Statistical analyses revealed significant differences between the subject groups on the LiSN-S test (low-cue SRT, high-cue SRT and overall), the ABR (wave III latency in the left ear and rate effects for wave V latency bilaterally), and the MLR (Pa amplitude on the right side). The peri-/post-menopausal group performed more poorly on the LiSN-S and had longer ABR wave V latencies with an increased rate of stimulation 23.3 clicks/sec versus 77.7 clicks/sec). The authors believed that the other statistically significant different electrophysiological measures between subject groups, which were unilateral, were due to the small number of subjects.
According to the authors, these data suggest that post-menopausal women with auditory complaints whose peripheral hearing is within normal limits should be evaluated for potential central auditory processing deficits.

If you have a dog or cat, you’ve probably seen their ears moving toward an interesting or startling sound. For professional equestrians, watching the ears of their horse allows them to gauge their shifting attention. Humans still have these same muscles, and even more interesting is their relationship to our brain and how we pay attention. …

Tai Chi is not just for increasing balance; it may also help improve cognitive performance. In a recent randomized controlled trial, study participants who practiced a form of Tai Chi twice a week for six months improved their scores on the Montreal Cognitive Assessment (MoCA) when compared to a control group (Fuzhong et al, 2023)….
Skyquakes—Did You Hear It?
The majority of people are familiar with earthquakes, but there is another phenomenon that is not nearly as predictable, and louder—skyquakes. Skyquakes are enigmatic sounds, typically described as a very loud boom or trumpet-sounding noise that has no apparent cause and seems to come from the sky. Their sound is like distant, but very loud, thunder with…
