This document is a song that summarizes key concepts about soundwaves, including compression, frequency, hertz, infrasonic and ultrasonic ranges, pitch, fundamentals, the sound frequency spectrum, octaves, bass, midrange, treble, equalization, amplitude, decibels, wavelength, velocity, harmonics, and phase. The song uses rhyming lyrics to explain these soundwave concepts in an entertaining and educational way.

2. SOUNDS LIKE YOU NEED
TO
FRESHEN UP

4. THIS IS A SONG ABOUT
SOUNDWAVES

5. AND IT GOES A LITTLE

6. SOMETHING

7. LIKE

8. THIS

9. IT’S THE SOUNDWAVE TEST
YOU COULD SAY IT’S THE BEST
IT AIN’T THAT HARD TO DO
COME ON I’LL WALK YOU THROUGH

10. SOUNDWAVES ARE
A VIBRATIONAL DISTURBANCE
THAT DEMANDS MECHANIC SERVANTS
MOVING MOLECULAR ENERGY
SCATTERING SOUNDS FOR YOU AND ME

11. COMPRESSION IS
BEGINNING WITH COMPRESSION
TO KICK OFF THIS RAPPING SESSION
SHORTENING THE RANGE OF SOUND
LET’S SEE WHAT ELSE WE FOUND

12. FREQUENCY
LET’S GET INTO FREQUENCY
COME ON AND SING WITH ME
THE NUMBER OF TIMES
PER SECOND SOUND VIBRATIONS RHYME

13. HERTZ ( Hz)
THEY’RE EXPRESSED IN HERTZ
A MEASUREMENT THAT WORKS
AN ANALYSIS OF FREQUENCY
FOR CPS NUMERICALLY
● CPS IS CYCLES PER SECOND

14. INFRASONIC
ONTO INFRASONIC
YOU KNOW IT HAS TO BE
THE RANGE BELOW THE FREQUENCIES
HEARD BY YOU AND ME

15. ULTRASONIC
ON THE OTHER HAND
ULTRASONIC BRINGING CHANGE
IT’S THE OPPOSITE OF INFRA
IT’S ABOVE OUR RANGE

16. PITCH
MOVIN’ ON TO PITCH
AND YOU KNOW IT’S PRETTY GREAT
IT’S THE HIGHNESS OR THE LOWNESS
OF THE SOUND THAT WE CREATE

17. FUNDAMENTAL
THE LOWEST FREQUENCY
OR THE FIRST HARMONIC
EITHER WAY YOU THINK OF IT
THE FUNDAMENTAL IS MELODIC

18. SOUND FREQUENCY SPECTRUM
SOUND FREQUENCY SPECTRUM
IS WHAT WE CAN HEAR
RANGING 20-20K Hz
NOW WE’RE SHIFTING INTO GEAR

19. OCTAVE
THE 2:1 RATIO IS CALLED AN OCTAVE
SIDE NOTE:
AN OCTAVE IS THE NOTE 1 AND 8 PUT TOGETHER TO
FORM A PERFECT TONAL PITCH

20. LET’S GET BACK ON
TRACK

21. BASS
BRINGING US TO BASS
THE LOW END OF WHAT OUR EARS PICK UP
RANGING 20-320Hz
THAT’S PRETTY DEEP-GET MY JOKE! AHEM

22. WASSUP

23. MIDRANGE
THE STUFF THAT WE CAN HEAR
THAT CAN MAKE US SHED A TEAR
320-2560
H-E-R-T-Z

24. CHORUS
IT’S THE SOUNDWAVE TEST
YOU COULD SAY IT’S THE BEST
IT AIN’T THAT HARD TO DO
COME ON I’LL WALK YOU THROUGH

25. TREBLE
NOW WHAT COMES NEXT
WE’RE LOOKING FOR TREBLE
THAT HIGH PITCH OCTAVE IS SUCH A REBEL

26. STILL TREBLE
5120-200KHz
THE HIGHEST OCTAVES AUDIBLE
TO YOU AND ME

27. EQUALIZATION
EQUALIZATION IS
A PROCESSING DEVICE
TO BOOST, FADE, OR SHELVE
FREQUENCIES TO MAKE THEM NICE

28. AMPLITUDE
AMPLITUDE
IT’S THE MAGNITUDE
IT’S A SOUNDWAVE OR AN ELECTRIC SIGNAL
MEASURED IN A DECIBEL

29. DECIBEL (dB)
IT’S A RELATIVE AND LIMITLESS UNIT
TO MEASURE RATIO OF TWO QUANTITES
IT’S EASY WHEN YOU THINK ABOUT IT
JUST A WAY TO MEASURE MULTIPLES CAN’T YOU SEE

30. WAVE LENGTH
THE LENGTH BETWEEN THE WAVE
IS WHAT COMES NEXT
IT’S EVEN IN THE NAME
WHAT MORE DID YOU EXPECT?

31. VELOCITY
SPEED IN A GIVEN DIRECTION
LIKE A FAST PACED RAPPING SECTION
VELOCITY IS AGILITY
COME ON, AND SING WITH ME

32. HARMONIC
THE FUNDAMENTAL FREQUENCY’S
MULTIPLE
IS WHAT HARMONIC’S ALL ABOUT
MAKE THE TONE SOUND FULL

33. PHASE
INTERACTION WITH
ONE WAVE OR ANOTHER
EITHER ACOUSTIC OR ELECTRIC
NOW WHAT DID WE DISCOVER?

34. IT’S THE SOUNDWAVE TEST
YOU COULD SAY IT’S THE BEST
IT AIN’T THAT HARD TO DO
COME ON I’LL WALK YOU THROUGH
