Dataset of sauna impulse responses

PLEASE NOTE that the dataset was updated in February 2025!

A dataset of impulse responses collected in the sauna at TUAS building of Aalto University, Espoo, Finland.

The measurement setup included:

Genelec 1030A loudspeaker with ampliefier removed

external Quad 240 power amplifier (outside of the sauna)

two Behringer ECM800 microphones

seven custom-made temperature and humidity loggers, controlled with Arduino

First 998 IRs were collected using 1-s sweeps, for the remaining 4201 IRs 2-s sweeps were used.

For more information IR analysis please see the paper "Exploring Sauna Impulse Responses" by Karolina Prawda, Nils Meyer-Kahlen, and Sebastian J. Schlech in proceedings of Internoise 2024.

How to read the files in the dataset:

The general style of file naming is:IR_Sauna_test_meas_2023_03_30Thh_mm_ss_0300.wav, where hh is hours, mm is minutes, ss is seconds.

For example, for IR measured at 12:55:01 the filename is:IR_Sauna_test_meas_2023_03_30T12_55_01_0300

The dataset is divided into two files, with IRs collected with 1-s and 2-s sweeps kept separately.

Temperature_humidity_sauna_30_03_2023_upload.xslx contains the temperature and humidity data for the 7 sensors

The dimensions along the Z-axis are: total height of the sauna 2.50m, loudspeaker 1.72m, near-field microphone: 1.67m, far-field microphone 1.95m, sensor 1: 0.69m, sensor 2: 1.52m, sensor 3: 1.02m, sensor 4: 0.68m, sensor 5: 1.35m,  sensor 6: 1.59m, sensor 7: 1.01m.
