The impulse response, when properly recorded, contains all the information about the acoustics of a steady-state room for a given set of source and receiver locations. Consider a single sound impulse emitted from a source in a room as shown in Figure 1. Figure 1. Direct and reflected sound paths in a room.

WebMar 17, 2024 · Direct to Reverberant Ratio (DRR) is measured for three non-idealised rooms of different sizes, using a variety of methods. Binaural room impulse response are compared to the DRR calculated from an omnidirectional room impulse response. Consistent differences were found in the absolute DRR values calculated from each type … WebReverberation(also known as reverb), in acoustics, is a persistence of soundafter it is produced.[1] Reverberation is created when a sound or signal is reflected. This causes numerous reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air.[2]
