“…During the Ottoman era, Sinan the architect placed ceramic pots within the domes to increase the sound absorption of the dome and to control the acoustical comfort of the congregation (3)(4)(5). There are various research concerned with the acoustical properties of both historic (3)(4)(5)(6)(7)(8) and contemporary mosques (6,9,10). However, there is a lack of research on individuals' subjective perception of the religious places.…”

This study presents a research that is concerned with the indoor soundscape in historical mosque. Hacı Bayram Mosque and its surroundings area of Hamamönü has been selected as the research site due to being the historical center of Ankara. Although there are studies concerned with the acoustical characteristics of mosques, there isn't enough research focusing on user's expectation and interpretation of the indoor soundscape within a historical space. This study adopts the user focused on Grounded Theory (GT) to capture individuals' auditory sensation and interpretation of the indoor soundscape within a historical mosque. In depth interviews are held with congregation of the mosque and with the individuals sitting around the surrounding area. Based on the their subjective responses, a theoretical framework is generated to gain an insight on the factors that affect individuals understanding and expectation from mosques. The conceptual framework generated through Grounded Theory (GT) shows how indoor soundscape may influence their individuals' response to the physical environment of the mosque showing the association between the soundscape elements, spatial function and sense of place.

“…From the descriptions of the mosque, a large prayer hall where the worshippers follow the leader, the acoustics should be the most significant determinant of the architectural design strategy (Hammad, 1990). The acoustical environment in the mosque is expressed concerning its reverberation time (RT) value (Eldien and Qahtani, 2012;Ismail, 2013). Other requirements to be fulfilled are sufficient loudness, widespread sound distribution, low background noise, and high speech intelligibility (Prawirasasra and Mubarok, 2017).…”

: Acoustical design as part of the audio comfort influences the architectural design strategy of a mosque significantly. As belonging to the speech room criteria, a mosque should meet some acoustic room requirements to deliver the solemnness to the worshipper during the prayer. Concerning this, the study aims to assess the indoor acoustics performance of Baiturrahman Grand Mosque, Banda Aceh. Baiturrahman grand mosque is an important place of worship for Acehnese and becoming a landmark of Banda Aceh City. The mosque which contains a lot of history of Aceh was built in heavy construction, i.e. concrete wall, marble coated floor, and concrete dome ceiling. Due to its significance, the room acoustics of the mosque as the primary design considerations in a speech room type is evaluated. The acoustics parameters estimated are Noise Criteria (NC), Sound Pressure Level (SPL), Reverberation Time (RT), and Rapid Speech Transmission Index (RASTI). The background noise was recorded for delivering the noise criteria and being the primary data carried out in the acoustic simulation. The study utilised CATT-Acoustic v7.2 software for simulating predicting SPL, RT, and RASTI.Abstrak : Desain akustik merupakan bagian dari parameter audio yang mempengaruhi desain arsitektur masjid secara signifikan. Masjid termasuk dalam kategori speech room yang harus memenuhi beberapa persyaratan akustik ruang untuk dapat menghadirkan kekhusyukan kepada jamaah selama sholat. Penelitian ini bertujuan untuk menilai kinerja akustik dalam ruangan Masjid Raya Baiturrahman, Banda Aceh. Masjid Raya Baiturrahman adalah tempat ibadah yang penting bagi orang Aceh dan menjadi simbol Kota Banda Aceh. Masjid yang memuat banyak sejarah Aceh ini terbuat dari dinding beton, lantai berlapis marmer, dan langit-langit kubah beton. Pada studi ini, parameter akustik ruang yang dievaluasi adalah Kriteria Kebisingan (NC), Tingkat Tekanan Suara (SPL), Waktu Gema (RT), dan Indeks Transmisi kecepatan Bicara (RASTI). Kebisingan latar belakang direkam untuk memberikan kriteria kebisingan dan menjadi data primer yang dilakukan dalam simulasi akustik. Studi ini menggunakan perangkat lunak CATT-Acoustic v7.2 untuk mensimulasikan prediksi SPL, RT, dan RASTI.

“…Ismail [21] highlighted that designers do not pay enough attention to the acoustic performance in prayer halls due to projects' time limitation and insufficient basic guidelines for better acoustic performance during the early design stage. He investigated the acoustic performance of contemporary mosques by using computer model based on ray tracing theory.…”

This chapter presents a detailed analysis to identify the best Mihrab (prayer niche of Imam) geometry with respect to acoustic performance of mosques. Mihrab geometry has an impact on daily prayer recitation and orders, as the Imam (prayer leader) faces this semicircular shape. Sound pressure level (SPL) has been simulated to compare different well-known designs and geometries of Mihrab by ODEON. A typical mosque in an educational campus was considered for the study, and it is found that Safavid Mihrab geometry has the best performance followed by Chinese, Mughal, and Tulunid Mihrab geometries, while the worst performance is found in Almoravid Mihrab geometry. This study obviously guides the mosque designers to choose the appropriate Mihrab geometry with regard to the acoustic performance.
