The human voice is produced by the vocal cords. When air is blown from the lungs through the larynx, the vocal cords vibrate at a frequency and produce sound. When these sound waves pass through our mouth and tongue, its pitch and quality are changed and the sound waves are converted into understandable speaking. The audible range of sound for human beings extends from about 20 Hz to 20000 Hz. Any sound outside this hearing range is undetected by human ears regardless of its amplitude. • Let us learn more about it in this video. • #howhumansproducesounds #sounds #physics • Subscribe to our channel to watch free online lectures • For more videos, online classes, 24X7 Doubts solving and Mock tests, Visit Toppr - The better learning app. • #BetterLearning on the Toppr app, download now • Google Play: http://bit.ly/2vRBqcb • App Store: http://apple.co/2vpRAr9 • Website: https://www.toppr.com/ • Download Doubts on Chat App: • Android Play Store: http://bit.ly/2B6w7oy • iOS App Store: http://apple.co/2ziAA75 • Facebook: / beingtoppr • Twitter: / mytoppr • Instagram: / mytoppr • LinkedIn: / toppr-com
