Evaluate five potential drivetrain modifications to reduce system noise and begin implementation if deemed feasible.

Mechanical Engineering Co-Op
Must consider short & long term solutions
Must reduce noise by reducing decibels and improving sound quality
Drivetrain must not slip when a high impulse is applied
I used online resources such as drivetrain design manuals to determine possible drivetrain modifications that would reduce audible noise during a stoke of the Hydrow. I also coordinated with belt suppliers and our manufacturing partners to determine the best path forward in the short & long term. Potential solutions included tighter manufacturing quality control criteria and changes in belt supplier, belt coating, and belt type.
Testing was performed on all changes prior to implementation determine their overall effect on system noise including decibels produced and sound quality.
Belt 1 - Decibels
Belt 2 - Decibels
Two drivetrain changes were implemented during my co-op, while two longer-term changes have shown promise. After further validation, these two additional changes may replace the current drivetrain to further reduce system noise.
