The superficial layer of the lamina propria loses density as it becomes more edematous. The intermediate layer of the lamina propria tends to atrophy only in men. The deep layer of the lamina propria of the male vocal fold thickens because of increased collagen deposits. The vocalis muscle atrophies in both men and women.
In native speakers of American English, young women use vocal fry more frequently than men. When asked to read a passage, female speakers used vocal fry at a rate four times higher than male speakers. [12] Creaky voice is frequent in a number of languages, including Finnish, where it serves as a cue for phrase-boundaries and turn-taking. [13]
Adult men and women typically have different sizes of vocal fold; reflecting the male–female differences in larynx size. Adult male voices are usually lower-pitched and have larger folds. The male vocal folds (which would be measured vertically in the opposite diagram), are between 17 mm and 25 mm in length. [ 10 ]
But the inertia inherent in its mass resists acceleration—and all changes in cone position. Additionally, speaker cones will eventually suffer tensile fatigue from the repeated shaking of sonic vibration. [6] Thus conventional speaker output, or the fidelity of the device, is distorted by physical limitations inherent in its design. These ...
For example, a typical electrodynamic speaker driver can have a moving mass of tens or hundreds of grams, whereas an electrostatic membrane only has a mass of a few milligrams, several times less than the very lightest of electrodynamic tweeters. The concomitant air load, often insignificant in dynamic speakers, is usually tens of grams because ...
Nearly a dozen men have entered the race for speaker since Kevin McCarthy was ousted, not a single woman has joined them. 'Too smart to want the job': Why no women are running for speaker of the House
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
For example, while sound travels at 343 m/s in air, it travels at 1481 m/s in water (almost 4.3 times as fast) and at 5120 m/s in iron (almost 15 times as fast). In an exceptionally stiff material such as diamond , sound travels at 12,000 m/s (39,370 ft/s), [ 2 ] – about 35 times its speed in air and about the fastest it can travel under ...
