notes light and water moove in transverse wave sound moves in a longitutal wave. rare fra tin is when sound molecules are being pulled together and pushed apart compression and rare fraction. yo sounds opposite will cancel out first component is relized aspitch to complete a wave is a cycle how many times repeated is frequency hienreich herzt is named after wavelengths called hertz the highr the wave the louder the sound. the closer together the peaks itmeans the pitch is higher f= 1 hz if you doulble a frequency u get an octave. One octave increase doubles the frequency 440hz foubled 880 20 to 20,000 hz or no khz loudness+ amplitude and volume.120 db is the threshold of pain for sound fundemental 2 ocatvive fith is third degrre of scale 4th then fith again iover tone and harmonic seriesigne wave most genral wave you can create. odd har,onics are triangular and drop off quicker. Soft wave consists off all harmonics

 white noise is used to test frequency to frequency's to create complex wave form.  sounds closer together make doppler effect. to alter wave forms. haveto tune out third pitch will make sound become quicker.

wav notes. the air we breath is a type of wave the molecules vibrate as they travel from the source to the ear. also when a musician srikes an instrument we usually here the sound emeditly though through speakers.... sound can be captured or converted through a microphone by flucuation in air pressure

the harmonic frequencys 200 and over200hz 300 hz 400hz and the fundementol being 440.

The overtone is the second harmonic second overtone is third harmonic so on and so fourth. Sine square triangle and sawtooth are all wave forms of harmonic spectra. The ratio 1/harmonic means that the harmonic has an amplitude of 1/1 THe ratio 1:third harmonic will have an amplitude of 1/9. One ninth the strength of the fundemental. the fith harmonic should have an amplitude 1/25 one twenty fith of the fundementals strength.

 In a square wave every other harmonic is absent. They are missing because of the waves duty of cycle. the duty of the square wave is always 1/2 Because the cycle is 1/2 the second harmonic isnt present. Bt if the cycle is over 50% it becomes a rectangular wave form. A pulse wa

wave shape project

1 the wave shape is is sine waves. When rising the pitch the graph becomes tighter. by amplifyinh it creates square waves. it goes from positive to negative negative to positive. it strechesout the wave

wave 2 1. these are rectangular waves. 2 this wave does sound diffrent it is higher pitched with a faster tempo.

wave 3 1.These are sawtooth waves. 2. THe sound qualatiy of this wave is high pitched with a moderate tempo. 3. These three waves all sound diffrent because of the fact they are all diffrent types of waves was tooth sine and rectangular.

Wave 4 it is jagged with a straight line through the middle because this is white noise. THe wave shape is altered into just a flat line making white noise. it is a very high pitch THat all sounds vary extremeley but are all very crucial in the music industry when creating a song. **1.** **Compression**  **2.** **Rarefaction**  **3.** **Motion of sound**  **4.** **Three components loudness quality and harmonics**  **5.** **Frequency**  **6.** **Hertz comes from hienriech hertz the closer together the wave engths the more hertz. lowest level hertz you can hear is 0 if you double the hertz you get an octave.** <span style="font-family: arial,helvetica,serif; font-size: small;"> **7.** **CPS** <span style="font-family: arial,helvetica,serif; font-size: small;"> **8.** **Positive and negative polarity** <span style="font-family: arial,helvetica,serif; font-size: small;"> **9.** **Period** <span style="font-family: arial,helvetica,serif; font-size: small;"> **10.** **Harmonic Series fundemental** <span style="font-family: arial,helvetica,serif; font-size: small;"> **11.** **Timbre** <span style="font-family: arial,helvetica,serif; font-size: small;"> **12.** **Saw tooth Wave, Triangle wave, Sine Wave, Square Wave in square waves harmonics are absent.** <span style="font-family: arial,helvetica,serif; font-size: small;"> **13.** **Complex Wave** <span style="font-family: arial,helvetica,serif; font-size: small;"> **14.** **Difference between white and pink noise** <span style="font-family: arial,helvetica,serif; font-size: small;"> **15.** **Volume** <span style="font-family: arial,helvetica,serif; font-size: small;"> **16.** **Decibels or db cannot here 0 db and becibls is the measure of volume** <span style="font-family: arial,helvetica,serif; font-size: small;"> **17.** **Amplitude** <span style="font-family: arial,helvetica,serif; font-size: small;"> **18.** **Threshold of Pain 120** <span style="font-family: arial,helvetica,serif; font-size: small;"> **19.** **Threshold of hearing 20** <span style="font-family: arial,helvetica,serif; font-size: small;"> **20.** **Perceived doubling of volume** <span style="font-family: arial,helvetica,serif; font-size: small;"> **21.** **Speed of sound 1100mps but depends on tempature** <span style="font-family: arial,helvetica,serif; font-size: small;"> 22. **Sonic Boom! when an air vehicle breaks the sound barrier** <span style="font-family: arial,helvetica,serif; font-size: small;"> 23. **Phase cancellation** <span style="font-family: arial,helvetica,serif; font-size: small;">//<span style="font-family: Arial,Helvetica,sans-serif; line-height: normal;">What properties of sound, when modified, have the greatest potential to alter human response and emotion and why?

ALso the amount of decibles and the aplitude and lower amount of hertz affects it. To add to that with the higher frequencie vocals and higher frequencie instruments they appear to us as smoother and more "meant to be" harmonics and harmonies. But when the
