This study investigates how microphone choice and placement affect the perceptual quality of tom drum recordings. Six widely used microphonesAKG C414, AKG D40, Audix D2, Audix D6, Sennheiser MD421, and Shure SM57were evaluated across three tom sizes (10", 12", and 16") and two microphone positions (Centre and Rim). Recordings were captured under controlled studio conditions, utilising a robotic drum beater for consistent performance, and rated by 25 listeners with audio engineering backgrounds. Statistical testing was used to evaluate significant ratings of microphones, as well as if ratings differed between tom sizes and between microphone position. Friedman tests indicated significant differences in preference across microphones. Subsequent pairwise comparisons using the Wilcoxon signed-rank test revealed context-dependent perceptual differences between microphones, with several models showing strong performance only for specific tom sizes and positions. Results also showed that the same microphone could be rated significantly different depending on placement or drum size, highlighting the importance of context in microphone selection. These findings suggest that tailoring microphone choice and position for each tom can improve perceptual outcomes.
