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

2 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.”

3 DEMO TIME TO PLAY SOME FLUTE!

4 Example of Feedback: the echo phaenomenom

5 an experiment with you! And now....

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

7 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.

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

9 Now, a more challenging task Time to sing!

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

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

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