9-17 Waveform is not a reliable way to determine if something is periodic Voicing is always a periodic event Resonator Each different size represents a different frequency sound A physical way of doing Fourier Analysis Can identify pure tones that are occuring in complex sounds Key factor: size of the air column Shape of the air column Materials that comprise the bottle Sound waves oscillate through air and mediums that are solid The bigger the resonator, the lower the frequency As the volume of air inside resonator changes, the actual wavelengths of sound that fit perfectly within that space are going to get longer Longer wavelengths mean lower frequencies Resonators as Filters - what you put in is different than what comes out! (spherical) Bandwidth/damping Regularly shaped acoustic resonator Narrowly tuned and lightly damped Way of describing how wide the mountain is At what width along the frequency have we dropped 3dB (3dB down

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
