Abstract:
Mixed Reality applications aim to create plausible virtual sound sources in a real environment. This work presents a Spatial Room Impulse Responses dataset with high spatial resolution to enable comparison of virtual renderings with measured room acoustics.The measurements were conducted in a hallway and staircase of a reverberant university building using a robot equipped with a microphone array. Multiple sound sources were placed in the hallway and the two adjacent staircases. The dataset features sources on the same floor as the microphone and on the floor below. In one subset of the dataset, microphone positions are evenly distributed with a coarser spatial resolution across the entire length of the hallway. In the other set, measurements with higher spatial resolution were taken for the transition between the hallway and the staircases.This dataset can be used, for example, for validating room acoustic simulations and impulse response interpolation or extrapolation algorithms. The arrangement of the sources enables thorough investigations of room coupling and occluded sound sources in the measured environment.
