The content discusses the fundamentals of acoustics, focusing on sound refraction, the anatomy of the ear, and how sound ...

Jan. 27, 2025 — Various diseases can be treated by stimulating the vagus nerve in the ear with electrical signals. However, this technique does not always work. A study has now shown ...

A new study in the journal Nature throws a new theory into the fray. Analyzing a wealth of DNA collected from fossilized human bones, the researchers found that the first Indo-European speakers ...

Yet, despite being functionally obsolete, the muscles around the human ear—the auricular muscles—still activate when we focus on specific sounds. Scientists at Saarland University in Germany ...

The authors reasoned that many similarities between the appearance of cartilage under the microscope for zebrafish gills and human ears cannot be just a coincidence. Knowing that both the gills ...

Tens of millions of years ago, our primate ancestors responded to noises in much the same way many other mammals do, pricking their ears and deftly turning them towards the sound's source. While a few ...

Summary: Humans have vestigial ear muscles that once helped our ancestors focus on sounds. New research shows these muscles still activate when we strain to hear in noisy environments. Scientists used ...

Yale researchers discovered new cochlear hearing modes that influence how the ear amplifies sound and processes frequencies. Yale physicists have uncovered a sophisticated and previously unknown set ...

Research links human outer ears to cartilage in fish gills. Gene-editing experiments confirm evolutionary connection. Findings date back to marine invertebrates 400 million years ago. New research has ...

Physicists have discovered a sophisticated, previously unknown set of 'modes' within the human ear that put important constraints on how the ear amplifies faint sounds, tolerates noisy blasts ...
