I've been having a headache weekend.
Sound waves do not really bend around corners or curves, am I correct?
Your Pink insulation sound shield in reality just bounces the sound waves back and forth since the surface is too smooth to distort the sound waves, possibly causing a vibration?
Using an Acoustical panel with multiple holes, nocks and crannies absorbs more of the sound waves?
How would the use of:
1---1/8" thick panelboard, the type with holes used for hanger hooks, painted with Boron for fire proofing on the engine side
2---1/2" to 1" acoustic foam board with a 1/8" to 1/4" thick or same as #1 with raised foam cut in different sizes and shapes to distort the sound waves, attached but with no holes lining up between # 1 & 2
3---1" thick outer panel.
Total thickness about 2 1/2" on the sides and ends. The top should be the least worry.
An opening for the installation of a heat exhaust fan and cooling fans would still be used.
OR use of Silent Panel which is fire proof but possibly expensive.
