The most soaring vocal melody is in Johann Sebastian Bach's Mass in B Minor. In one section, the basses, tenors, altos, and sopranos carry the melody from a low D to a high A. In concert pitch, these notes are now assigned frequencies of 146.6 Hz and 880.0 Hz. FInd the wavelengths of a) the initial note and b) the final note. Assume the chorus sings the melody with a uniform sound level of 75 dB. Find the pressure amplitudes of c) the initial note and d) the final note. Find the displacement amplitudes of the a) initial note and b) the final note. part c and d should be in pascals.
