This is part of a dataset of organ recordings and room acoustic measurements of St. Jakobus Church, Ilmenau. For an overview of the complete dataset, please refer to Room and Organ Acoustic Measurements of St. Jakobus Church Ilmenau.
\nThis dataset is an collection of Spatial Room Impulse Responses (SRIRs) for multiple source receiver combinations in the church. The zip files contain SOFA files that contain all the data like the SRIRs themselfs, source and receiver positions, and other metadata. The files follow SOFA (v. 2.1) convention SingleRoomSRIR 1.1 in accordance with AES69-2022.
\nMicrophone arrays based on Erathworks M30 microphones in the center with 6 electret capsules spherically distributed around that were used as receivers. The design of the arrays follows the recommendation of Optimizations of the Spatial Decomposition Method for Binaural Reproduction, for the measured RIRs to be used with the Spatial Decomposition Method for binaural rendering.
With a binaural reproduction in AR/VR with a free moving user in mind, a grid of positions on the ground floor was measured.
For that, a robotic platform equipped with the microphone array and approached 37 positions in the nave.
This includes positions between the pews, underneath the galleries and the organ and behind columns.
The rear section of the church, beneath the gallery where the organ is located, can be separated by a movable glass wall.
The RIR measurement swith the robot were performed once without and once with this glass wall installed.
When churches are converted for other uses, parts of the building may be structurally separated from one another.
In this case, the glass wall is intended to simulate such a change, or at least provide an indication of how something like this would affect the acoustics. ROAM-JIL-Open.zip containes the measurments without the glass wall, ROAM-JIL-Closed.zip the ones with the glass wall installed.
Additionally, three measurements on each of the two levels of galleries where conducted by hand above the middle of the nave. These measurements are in ROAM-JIL-Gallery.zip.
\nA subwoofer and two loudspeakers were positioned as close as possible at the mouths of the facade pipes without risking damage to the organ. To mimic the pipes radiation pattern, directional studio monitors (Genelec 7360A and 8341A ) where chosen. On the opposite side of the church, in front of the altar, an omnidirectional source (Outline GSR Speaker and Subwoofer) was placed in order to have a significantly different place of excitation and to be able to perform room acoustic analyses in the classical sense.
\nExponetial Sine Sweeps with a length of 15 s and 4 s of decay time were used as excitation signal. For the Genelec Subwoofer, the signal ranged from 18 Hz - 1 kHz, for all other loudspeakers from 20 Hz - 22 kHz.

The EU Open Research Repository serves as a repository for research outputs (data, software, posters, presentations, publications, etc) which have been funded under an EU research funding programme such as Horizon Europe, Euratom or earlier Framework Programmes.
\nThe community is managed by CERN on behalf of the European Commission.
\nZenodo’s general policies and Terms of Use apply to all content.
\nThe EU Open Research Repository accepts all digital research objects which is a research output stemming from one of EU’s research and innovation funding programmes. The funding programmes currently include:
\nHorizon Europe (including ERC, MSCA), earlier Framework Programmes (eg Horizon 2020) as well as Euratom.
\nIn line with the principle as open as possible, as closed as necessary both public and restricted content is accepted. See note on how Zenodo handles restricted content.
\nEU programme beneficiaries are eligible to submit content to the community. The community supports three types of content submissions:
\nSubmission via an EU Project Community (through user interface or programmatic APIs).
\nSubmission directly to the EU Open Research Repository.
\nAutomated harvesting from existing Zenodo content.
\nA representative of an EU project may request an EU Project Community and invite other project participants as members of the community. The project community is linked to one or more European Commission grants. All records in the project community are automatically integrated into the EU Open Research Repository immediately upon acceptance into the project community.
\nAny user may submit a record directly to the EU Open Research Repository. The submission will be moderated by Zenodo staff for compliance with the minimal required metadata requirements and its correctness.
\nRecords found among Zenodo’s existing content will on a regular basis automatically be integrated if they are found to comply with the requirements. The submissions through this method are integrated into the EU Open Research Repository with delay in a fully automated way.
\nRecords in the EU Open Research Repository are required to comply with the following minimal metadata requirements:
\nVisibility: Both public and restricted (with or without embargo and/or access request)
\nResource types: All resource types.
\nLicenses: Public and embargoed records MUST specify a license. The chosen license SHOULD be compliant with the Horizon Europe open science requirements (see Open Science in Horizon Europe)
\nFunding information: Records MUST specify at least one grant from the European Commission.
\nCreators: Creators SHOULD be identified with a persistent identifier (e.g. ORCID, GND, …), and affiliations SHOULD be identified with a persistent identifier (e.g. ROR, ISNI, …)
\nSubjects: Records SHOULD specify one or more fields of science from the European Science Vocabulary.
\nThese metadata requirements comes from the related open science requirements in Horizon Europe which are detailed in each project's grant agreement.
\nAll submissions undergo automated curation checks for compliance with the policy. Submissions through project communities are in addition reviewed by the project community. Submission directly to the EU Open Research Repository is in addiotn reviewed by Zenodo staff.
\nCommunity curators may at any point edit metadata of the records in the community without notice through human or automated processing. The curators may at their sole discretion remove records from the community that are deemed not to comply with the content and curation policy or which are deemed of insufficient quality.
\nThe content and curation policy is subject to change by the community owner at any time and without notice, other than through updating this page.
