Links between spatial impulse response and binaural dynamic responsiveness in concert halls

Recent research at Aalto University suggests that binaural dynamic responsiveness (BDR) in concert halls is (a) desirable and (b) a result of interaction between the emphasis of higher overtones at stronger dynamic levels and the early response of the room; also that tall, narrow, parallel sided “sh...

Description
Summary:Recent research at Aalto University suggests that binaural dynamic responsiveness (BDR) in concert halls is (a) desirable and (b) a result of interaction between the emphasis of higher overtones at stronger dynamic levels and the early response of the room; also that tall, narrow, parallel sided “shoebox” halls have a greater degree of BDR than wider non-shoebox geometries. We have been analyzing the time evolution of spatial impulse responses and their connection to room geometry. In a recent paper, we looked at how wall tilt affects the growth of lateral energy in the room. In this paper, we consider how the shape of forward integrated lateral energy in a spatial impulse response may affect perceived strength, spaciousness, and binaural dynamic responsiveness.
