Answer
lower; musical note $D$
Work Step by Step
Based on the given table, with a musical note of E, the pitch is $329.63$ $Hz.$
Using the given formula, $
h=\dfrac{a}{1-\dfrac{s}{770}}
,$ then
\begin{array}{l}\require{cancel}
329.63=\dfrac{a}{1-\dfrac{50}{770}}
\\\\
329.63=\dfrac{a}{\dfrac{770}{770}-\dfrac{50}{770}}
\\\\
329.63=\dfrac{a}{\dfrac{720}{770}}
\\\\
329.63=a\div\dfrac{720}{770}
\\\\
329.63=a\cdot\dfrac{770}{720}
\\\\
329.63=\dfrac{770}{720}a
\\\\
\dfrac{720}{770}(329.63)=\left(\dfrac{770}{720}a\right)\left(\dfrac{720}{770}\right)
\\\\
\dfrac{720(329.63)}{770}=a
\\\\
a=308.22545454545454545454545454545
.\end{array}
With $a\approx308,$ then the actual pitch the observer hears is lower than the real pitch. The actual pitch heard is closer to the musical note $D.$
