  The cosmic microwave background (CMB) radiation offers a unique avenue for
exploring the early Universe's dynamics and evolution. In this paper, we delve
into the fascinating realm of slow-roll inflation, contextualizing the
primordial acoustic perturbations as the resonant echoes akin to the iconic
sound of Chewbacca from the Star Wars universe. By extrapolating polynomial
potentials for these primordial sounds, we illuminate their role in shaping the
inflationary landscape. Leveraging this framework, we calculate the scalar
spectral index ($n_s$) and tensor-to-scalar ratio ($r$), providing insights
into the underlying physics governing the inflationary epoch. Employing a
rigorous chi-square ($\chi^2$) analysis, we meticulously scrutinize the Planck
data combined with that offered by the BICEP/Keck collaboration to identify the
Chewbacca sound profile that best aligns with observational constraints. Our
findings not only shed light on the intricate interplay between sound and
cosmology but also unveil intriguing parallels between the cosmic symphony of
the early universe and beloved cultural icons.
