Megahertz sound waves
An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. The generally accepted standard hearing range for humans is 20 to 20,000 Hz. In air at atmospheric pressure, these represent sound waves with wavelengths of 17 metres (56 ft) to 1.… WebThe lower the amplitude the softer the sound. HOW YOU MAKE SOUNDS We use our vocal cords to make sounds in our throat. When we speak, our vocal cords vibrate. Place your hand on your throat when you talk, and you can feel the vocal cords vibrate. How does the ear work? Sound Waves Sound waves are sent. The outer ear “catches the sound …
