The RIRs were measured in seven different rooms at UTS Tech Lab, including an anechoic environment (a hemi-anechoic chamber with 50 mm Martini Absorb XHD50 sound absorbing materials on the ground), a hemi-anechoic chamber, a small meeting room, a medium meeting room, a large meeting room, a shoe-box room, and an open-plan office. A circular array of 60 loudspeakers was installed in each room, with two microphone arrays placed sequentially in five different zones inside the loudspeaker array. <br/><br/> In the experiments, four Yamaha RIO1608-D2 and four Yamaha RIO8-D audio interfaces were daisy chained to form a 64-input-64-output audio system that communicates with a computer through a Dante virtual sound card. Both the loudspeaker (Genelec 8010A) and microphone (DPA 4060) arrays were connected to the audio interfaces for simultaneous sound generation and acquisition. During the measurements, a 3 s long logarithmic sine sweep signal from 20 Hz to 22 kHz was generated in MATLAB with a sampling rate of 48 kHz and reproduced through each loudspeaker, and the sound pressure in each zone was captured by either the square or double-layer circular microphone array. <br/><br/>The database consists of 260,400 RIRs, among which 134,400 were measured by a square microphone array and 126,000 were measured by a double-layer circular microphone array. Each impulse response is stored as a 24-bit single-channel WAV file at a sampling rate of 48 kHz, with the naming convention of “Room_Zone_MicrophoneArrayType_LoudspeakerIndex_MicrophoneIndex.wav”. For example, “AnechoicRoom_ZoneA_CircularMicrophoneArray_L1_M2.wav” is the impulse response from the first loudspeaker to the second microphone of the double-layer circular microphone array that is placed at Zone A in the anechoic room. <br/><br/>Detailed descriptions of the rooms, equipment, experimental setup, and measurement procedure are provided in the companion paper submitted in the Journal of the Acoustical Society of America, which is available at: <a href='https://asa.scitation.org/doi/abs/10.1121/10.0014958'>https://asa.scitation.org/doi/abs/10.1121/10.0014958</a>"
