<description descriptionType="Abstract">&lt;p&gt;&lt;strong&gt;DESCRIPTION&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;This dataset includes acoustic impulse response (AIR) measurements made using an Eigenmike em32 and the room impulse response measurements carried out at the same position using an Alctron M6 measurement microphone. The measurements were made in classroom S05 at the METU Graduate School of Informatics on 23 January 2018.&amp;nbsp;&lt;/p&gt;

&lt;p&gt;The dataset is released under the Creative Commons Attribution-NonCommercial-ShareAlike 4.0 license (https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode).&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;MEASUREMENTS&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;The classroom in which the measurements were made has a high reverberation time (T60 &amp;asymp; 1.12 s) when empty. The room is approximately rectangular and has the dimensions 6.5 &amp;times; 8.3 &amp;times; 2.9 m. AIR measurements were made at 240 points on a rectilinear grid of 0.5 m horizontal and 0.3 m vertical resolution surrounding the array. The array was positioned at a height of 1.5 m. The measurement planes were positioned at the heights of 0.9, 1.2, 1.5, 1.8 and 2.1 m from the floor level. These positions cover the whole azimuth range and an elevation range of approximately &amp;plusmn;50◦ above and below the horizontal plane.&lt;/p&gt;

&lt;p&gt;The sound source was a Genelec 6010A two-way loudspeaker whose acoustic axis pointed at the vertical axis of the array at all measurement positions. Logarithmic sine sweep method was used for the AIR measurements.&amp;nbsp;&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;FILE FORMAT&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;The AIRs and RIRs are provided as 16-bit signed integer WAVE files. The sampling rate is 48 kHz.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;NAMING CONVENTION&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;There are two folders: em32 and alctron. The former includes AIR measurements, and the latter includes the RIR measurements. Each of these folders include 244 subfolders where each subfolder is named as ABC, from 000 through to 664. See documentation.pdf for details.&lt;/p&gt;

&lt;p&gt;Note that the measurements right above and below the array are not ideal since the acoustic axis of the loudspeaker did not face the array. Therefore, these measurements are considered unfit and were not used in the publications given below.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;HOW TO CITE&lt;/strong&gt;&lt;/p&gt;
