Use your birthday in years (since the beginning of year 1) as the frequency of a pure tone.(Hint: what is the closest A note? How many semitones separate itĬalculate the difference geometrically, as a ratio, i.e. Multiply latter by frequency interval between A 7->C 8 The lowest note on an 88-key piano (A 0) and the highest (C 8)? What is the range between the fundamental frequency of.What is the frequency ratio of a half-octave?.
#Soundnote mathematica plus
What is a musical fourth (P4) plus a musical fifth (P5)?.
Confirm that a frequency ratio of 4/3 corresponds approximately to P4: a musical fourth (five semitones).Confirm that a frequency ratio of 3/2 corresponds approximately to P5: a musical fifth (seven semitones).There are 12 semitones in an octave (8 ve) on a piano, these are 5 black notes an 7 white notes.Don't forget that a pressure ratio needs to be squared. The human pain threshold is about 120 dB SPL.
(Hint: What is the inverse operation to Log?) Multiply by 10 to convert from bels to decibels.) Use the //N Mma suffix to get a numerical answer.
