Auditory environment in the museums: the case of Erimtan archaeology and arts museum
(Institute of Noise Control Engineering(INCE), 2019-06) Yılmazer, Semiha; Orhan, Cemre
The aim of this paper is to conduct a qualitative research to clarify the auditory environment in the museums. Research has taken place in the Erimtan Archaeology and Arts Museum which exhibits more than 2000 objects from Yüksel Erimtan’s collection of Anatolian archaeological artifacts. It is located near the main gate of Ankara Castle. While the scale and the façade of the building are connected contextually to its historic environment, the interior provides the contemporary experience to its visitors. Grounded Theory (GT) is used in this paper to create a conceptual framework, and clarify visitors’ perception of the soundscape in the museums. Semi-structured interviews are held with participants who are chosen among the visitors after they tour the museum on their own, until the data reaches theoretical saturation. Constant comparison method is used for analyzing the data and creating a conceptual framework which is compared with previous studies and the ISO 12913-1: 2014. According to the findings, context is determined as one of the core categories similarly to other studies. And some categories differ because of the various function of indoor space.

A comparative study on indoor soundscape in museum environments
(2019-07) Orhan, Cemre
The aim of this study is to understand how visitors perceive and compare the soundscapes of different museum environments. To reach this goal, physical parameters as acoustic measurements, and perceptual data as questionnaires and interviews were explored in Rahmi M. Koç Museum, and Erimtan Archaeology and Arts Museum. Both museums are located near the main gate of Ankara Castle, which is one of the most historic and cultural part of the city. To find out the acoustical parameters of the case study settings, Equivalent Continuous A-weighted Sound Level (LAeq) was measured in-situ with Bruel & Kjaer 2230 sound level meter, and Speech Transmission Index (STI) and Reverberation Time (T30) were measured with the Odeon Room Acoustics Software 13.01. For the perceptual data, the questionnaires were analyzed by using SPSS program. Interviews were analyzed with the Grounded Theory (GT) method to explore the visitors’ perception towards the indoor soundscapes of museum environments. After analyzing the data of interviews, the conceptual framework was created. This process was completed with the ATLAS.ti Software. Results showed that the soundscapes of the indoor environment cannot be explored only with physical parameters. Results showed that visitors’ perception of soundscape changes according to the theme of the museums, and visitors’ preference of sound environment changes according to the building types.

Harmony of context and the built environment: soundscapes in museum environments via GT
(Elsevier Ltd, 2021-02) Orhan, Cemre; Yılmazer, Semiha
This paper presents an approach to analyze visitors' expectations and perceptions of museums' built and auditory environments. It aims to explore visitors' perception of acoustic and built environments in museums, generate a systematic categorization, and create a conceptual framework using the Grounded Theory (GT) approach. We measured the Equivalent Continuous A-weighted Sound Level (LAeq) and, following the ISO/TS 12913-2/3, conducted semi-structured interviews and questionnaire surveys were conducted to discover the sound environments and capture the subjective responses of visitors in two museums: the Rahmi M. Koç Museum (RMK) and the Erimtan Archaeology and Arts Museum (EAA) (both located in the most historical part of Ankara, Turkey). Although the selected museums offer two different experiences based on themes, exhibitions, and interior designs, we examined whether the museums’ soundscapes, connected contextually to the historical environment, could be perceived different from one another. Results show that Museum RMK, which has historical exhibitions and an historical building type, is more appealing to people's preferences and expectations than Museum EAA, which has historical exhibitions and a modern building type. The findings of the study reveal that peoples' perceptions are mostly dependent on the context in which sound is heard, rather than on sound levels in museums. In some areas, where sound was used as a design element, visitors had a better museum experience because they were able to interact with the exhibited objects on exhibit and feel as if they were living in a specific period.

The neonatal intensive care unit (NICU) context and the perceived soundscape: a grounded theory approach
(Sage Publications, Inc., 2024-07) Orhan, Cemre; Yılmazer, Semiha
Background:Studies address excessive sound levels and their adverse effects on infants in neonatal intensive care units (NICUs). However, objective measurements represent merely one aspect of the acoustic environment, and investigations into staff’s perceptions of the acoustic environment remain scarce in the NICU context. A holistic approach, soundscape, is needed to explore the acoustic environment in-depth. Aim:This study aims to (1) contribute to indoor soundscape literature and inform decision-makers of future NICU design and research by focusing on staff members’ perceptions of the soundscape and (2) explore whether there is a relationship between staff members’ perceptions of soundscapes and the built and acoustic environments of one NICU. Methods:Following the ISO/TS 12913-2/3 protocols, semi-structured interviews were conducted with 10 NICU staff members and analyzed using the grounded theory to generate a conceptual framework for NICU soundscapes. Results:The results indicated that the task-related sounds, including false alarms, were neutrally responded to as they evoked acceptance and adaptation behaviors. The sound sources perceived as irrelevant were responded to negatively. NICU staff indicated that although they expect to hear alarms clearly, specific features of alarms caused several physiological and psychological problems. Conclusions:The findings of the study revealed the importance of conducting a soundscape approach to investigate NICU acoustic environment in detail. The study showed that staff members’ perceptions and responses primarily depend on the context rather than on sound levels.

Understanding the effect of restorativeness in indoor soundscapes through a conceptual model
(Institute of Noise Control Engineering, 2021-08-01) Orhan, Cemre; Yılmazer, Semiha
The soundscape is defined as the acoustic environment perceived or experienced by a person or people. Soundscape research, where human perception is at the center, has generally been conducted on unwanted sound sources to identify sounds' negative health effects. Therefore, wanted sound sources and their impact on being exposed to soundscapes that may induce positive outputs on health has been neglected. People tend to be in places that reduce stress and increase restoration. However, many indoor places cause stress in our daily lives and decrease the quality of living. This study aims to generate the conceptual model that would be used to identify what causes stress indoors and what can be done to transfer these spaces into restorative ones from the soundscape perspective. To generate a comprehensive model, by centering the soundscape framework of ISO, its constructs were combined with Attention Restorative Theory (ART), Stress Recovery Theory (SRT), and Biophilic Design approach into positive and negative relations based on their effects on health.
