Sound and Feedback effect Science Market Presented by: Lin & Jonathan

What is sound? “Sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air, and water.”

DEMO TIME TO PLAY SOME FLUTE!

Example of Feedback: the echo phaenomenom

an experiment with you! And now....

…. to start, a small challenge Read the text in the next slide!... No interruptions!

Acoustics is the interdisciplinary science that deals with the study of all mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound.

…. and now, read it again with the headphone.... No interruptions!

Now, a more challenging task Time to sing!

The effect of the Feedback on the acoustic source Acoustic source: you No feedback

The effect of the Feedback on the acoustic source Acoustic source: you Lagged voice feedback

Feedback can make the source ‘unstable’! Acoustic source: you Lagged voice feedback
