The concept of horizon brightened acceleration radiation (HBAR) has broughtto us a distinct mechanism of particle production in curved spacetime. In thismanuscript we examine the HBAR phenomena for a braneworld black hole (BBH)which emerges as an effective theory in our $(3+1)$ dimensional universe due tothe higher dimensional gravitational effects. Despite being somewhat similar tothe Reissner-Nordstr$\ddot{\rm o}$m solution in general relativity, the BBH isunique with respect to its charge term which is rather the tidal charge. Inthis background, we study the transition probability of the atom due to theatom-field interaction and the associated HBAR entropy. Both the quantitiesacquire modifications over the standard Schwarzschild results and turn out tobe the function of the tidal charge. This modifications appear solely due tothe bulk gravitational effects as induced on the 3-brane. Studying the Wien'sdisplacement, we observe an important feature that the wavelengths of HBARcorresponding to the Schwarzschild and the BBH, deviate from each otherdepending on their masses. This deviation is found to be more pronounced forthe mass values slightly greater or comparable to the Planck mass.
