Abstract: The changes in acoustic properties of a room due to the presence of an audience play a crucial role in the acoustic design of performance spaces. Among other parameters, reverberation time as well as spatial and directional properties of the sound field may be altered, ultimately affecting the auditory perception of a listener within the audience. This necessitates a good understanding of the audience’s acoustic effects in order to achieve desired acoustic properties of the room when in use for performances. This contribution presents the results of room acoustic measurements carried out at the Christuskirche church within the scope of DAGA 2024 in Hannover. Before the choir concert taking place in the church, measurements with multiple microphones, a dummy head and a spherical microphone array were taken with and without the audience present. In addition to evaluating common room acoustic metrics, we analyze sound field parameters obtained from binaural and Higher Order Ambisonics impulse responses, applying the methodology of parametric sound field analysis to this room acoustic case study.
