Abstract | A critical requirement for popular music in live-sound applications is the achievement of a robust kick-drum sound presented to the audience and the drummer while simultaneously achieving a workable degree of acoustic isolation for other on-stage musicians. Routinely a transparent wall is placed in parallel to the kick-drum heads to attenuate sound from the drummer’s monitor loudspeakers, although this can cause sound quality impairment from comb filter interference. Practical optimization techniques are explored, embracing microphone selection and placement (including multiple microphones in combination), isolation-wall location, drum-monitor electronic delay and echo cancellation. A system analysis is presented augmented by real-world measurements and relevant simulations using a bespoke Finite-Difference Time-Domain (FDTD) algorithm. |
