Wine glasses, because of their hollow shape, are particularly resonant. Depending on our exposure to noise hearing sensitivity can start to decline in our twenties. The voice produces sound when air from the lungs vibrates the vocal chords in the throat. Science news, great photos, sky alerts. The researchers discovered that dogs like humans respond not only to the words we say to them, but also to the emotional tone of our voices. Some dogs are not so reactive to sounds. Sound Inaudible to Humans Can Be Recorded by Microphones Scientists have discovered the fastest possible speed of sound, a zippy 22 miles (36 kilometers) per second. And the singer also needs to hold that note for at least two to three seconds for the vibration to build up enough to cause the glass to shatter. Most dogs adapt well when their ears fail, and you can continue to communicate using body language and hand signals. WebHuman Speech Frequency The human voice typically falls between 300Hz and 3,000Hz, although some baritone voices can fall as low as 50Hz.
