Wirkung von Nachhall in Bildungsräumen

Individuals with an increased need for good hearing (e.g. due to hearing impairments or limited language skills) should be supported by the spatial situation to deal with their disadvantage. Therefore, in DIN 18041: 2016 requirements for the reverberation time are defined which should support audibility depending on the user group and context of use of a room. The requirements defined in DIN 18041: 2016 are based on the assumption that a reduction of the reverberation time leads to improved audibility when considering inclusion. The project ”Effects of Reverberation time in Educational Spaces“ deals with the question of whether it can be empirically proven that the application of DIN 18041: 2016 meets this requirement in practice, that is, whether the defined requirements are sufficient to meet the topic of inclusion from a room acoustical point of view. The research question was addressed by a literature review and a listening test. In this article the results of the literature review are reported
