Subjective Experience of Speech Depending on the Acoustic Treatment in an Ordinary Room.

ABSTRACT: In environments such as classrooms and offices, complex tasks are performed. A satisfactory acoustic environment is critical for the performance of such tasks. To ensure a good acoustic environment, the right acoustic treatment must be used. The relation between different room acoustic treatments and how they affect speech perception in these types of rooms is not yet fully understood. In this study, speech perception was evaluated for three different configurations using absorbers and diffusers. Twenty-nine participants reported on their subjective experience of speech in respect of different configurations in different positions in a room. They judged sound quality and attributes related to speech perception. In addition, the jury members ranked the different acoustic environments. The subjective experience was related to the different room acoustic treatments and the room acoustic parameters of speech clarity, reverberation time and sound strength. It was found that people, on average, rated treatments with a high degree of absorption as best. This configuration had the highest speech clarity value and lowest values for reverberation time and sound strength. The perceived sound quality could be correlated to speech clarity, while attributes related to speech perception had the strongest association with reverberation time.

Project description:PurposeStressors due to the workload in the ambulance service are numerous and can be positively counteracted by work-related behaviors and experiences. We analyzed the subjective perceptions of workload and stress as a function of work-related behavior and experience patterns among emergency service personnel (EMP).MethodsA total of 276 EMP (94.6% men) participated (average age: 39.3 ± 8.04 years). Data on the stress situations of ambulance service staff according to the Slesina questionnaire, the Recovery-Stress Questionnaire (EBF), and the Questionnaire for Physical, Psychological and Social Symptoms (KOEPS) were obtained. Participants were classified into four patterns (A, B, G, and S) based on the Work-Related Behavior and Experience Patterns (AVEM) questionnaire.ResultsOverall, 32% of EMP were classified into AVEM risk patterns A and B. For half of the stress factors examined (23/46), the data were significantly different among the AVEM groups. Individuals with AVEM risk patterns have higher stress and lower recovery scores on the EBF and more physical, psychological, and social-communicative impairments shown using the KOEPS (all variables p < 0.001). Analyses showed moderate correlations among the AVEM dimensions (exceptions included striving for perfection, subjective importance of work, and work-related ambition), and the main scales of the EBF and KOEPS.ConclusionWork-related patterns of behavior and experience are used to determine how stress is handled, and it is possible to distinguish between patterns that promote health and those that hazardous to it. Individuals with AVEM patterns that are a risk to their health experience high stress, low recovery, and increased physical, psychological, and social-communicative impairments. Health-promoting work-related behaviors can be used to counteract stress. Companies developing preventive health promotion measures should focus on individuals with AVEM patterns that are a risk to their health.Supplementary informationThe online version of this article (10.1007/s10049-022-01076-y) contains further tables and figures.
