Students work scientifically to explore sound energy, and how it is sensed and produced. They investigate products that utilise sound energy (e.g. musical instruments) as well as how sound energy is recorded and represented by digital systems. They engage in a design and production task to develop a solution that uses forces and sound energy.

Sound energy. When you turn on a CD player you can dance to the music. The music travels as sound energy through the air from the speaker to your ears. Sound energy is produced by vibrating objects. If you gently touch the loud speaker, you can feel it vibrating with the music.

What is Sound Energy? (with pictures) - Info Bloom
SOUND. What is Sound? Sound is a form of energy, produced by rapidly vibrating objects, that can be heard by the human ear. Sound is a longitudinal wave. Most young people respond to sound frequencies of between 20 Hz and 20 000 Hz. Infrasonic- any sound with a frequency lower than 20Hz. Ultrasonic - any sound with a frequency above 20 000 Hz

What Is Energy
10.Sound Energy . is the type of energy produced when a force causes an object or substance to vibrate. The energy is transferred through the substance in a longitudinal wave. Stored Mechanical Energy. is energy stored in objects by the application of a force. Compressed springs and stretched rubber bands are examples of this type of energy.

Movement, sound, heat, and light provide evidence that energy is present and being used. Sound is produced when we strike something. But does sound do work? Yes, sound can move things. Sound waves move the tiny bones in your ears and shake windows when a loud truck passes by. Sound waves are also evident in the vibrations from playing a radio.

SOUND. A. Sound. 1. Is a form of energy produced and transmitted by vibrating matter. 2. Travels in longitudinal waves. 3. Travels more quickly through solids than liquids or gases – A medium (media pl.) is the matter though which waves travel.
