“…The primary aim is to identify the characteristics and influencing factors of sound fields in both the indoor and outdoor spaces of religious historical buildings. The simulated spaces include various structural forms, such as towering churches [19,24,60,70,91,92], domed mosques [40][41][42]93], and traditional Chinese Buddhist temples [18,50]. The most commonly used parameters in sound field simulation are reverberation time (RT) and early decay time (EDT), followed by the sound pressure level (SPL), sound clarity, and loudness.…”

Over the past decade, a substantial body of research exploring soundscapes in religious historical buildings has emerged, yet a comprehensive summary of this work is lacking. This paper selects 74 typical studies of soundscapes in religious historical buildings published between 2011 and 2022 to conduct quantitative statistics and visualization analysis from a bibliometric perspective. The selected literature is categorized based on the type of religious building, Christian, Islamic, or Buddhist. The literature is further segmented according to the research subject, including sound field studies, sound analyses, and evaluations of the acoustic environment. The research methods employed are also differentiated and include sound field measurements, acoustic simulations, questionnaires and auralization procedures. The analysis reveals pronounced disparities in research foci depending on the type of religious historical building. For instance, studies on the soundscape in Christian churches tend to focus on objective sound field attributes and frequently employ sound field simulations to analyse the acoustic parameters of diverse church spaces and materials. Conversely, research on the soundscape in Islamic mosques prioritizes speech intelligibility and acoustic comfort, while studies of the soundscape of Buddhist temples gravitate towards the impact of natural and religious sounds on individuals. This paper anticipates the future direction of soundscape research on religious historical buildings. Graphical Abstract

“…Previous studies have focused on the sound field analysis of churches (Pedrero et al, 2014;Luigi and Martellotta 2015;Giron et al, 2017), basilicas (Martellotta, 2009;Martellotta, 2016), cathedrals (Su arez et al, 2015;Alvarez-Morales et al, 2016;Martellotta et al, 2018;Anderson and Anderson, 2000), and mosques (Abdelazeez et al, 1991;Abdou, 2003;Su arez et al, 2018;S€ u and Yılmazer, 2008;S€ u G€ ul and C ¸alıs ¸kan, 2013a,b;S€ u G€ ul et al, 2014).

Exploration of room acoustics coupling in Hagia Sophia of İstanbul for its different states

_ Istanbul's Hagia Sophia is a monumental structure with multiple sub-spaces coupled to one another through arches. Its architectural elements have undergone alterations as its function has changed from that of a church to a mosque, a mosque to a museum, and back to a mosque. This study makes use of Hagia Sophia's rich formal and material characteristics to conduct a comprehensive investigation of room acoustics coupling. The methodology involves the application of the diffusion equation model (DEM) for sound energy flow analysis. Energy flow decays and energy flow dips are examined for almost 1000 receiver positions distributed throughout the various sub-spaces of the building. Ray-tracing (Ray-t) simulations are used to support the energy flow decay analysis conducted using DEM. The Ray-t data are subjected to Bayesian analysis to identify the decay parameters and the degree of acoustical coupling. Among the many variables, the source-receiver distance and positioning within different sub-spaces appear to be the underlying determinant of multi-slope sound decay pattern. On the other hand, the cases of multi-slope decays identified within the structure tend to weaken and single-slope cases increase when the overall absorption area increases in the mosque state due to the carpeted floor.

“…The aim of this paper is to present a more general method that allows for post-processing a pre-computed room impulse response (RIR) with a complete air attenuation profile (i.e., classical power-law absorption plus two relaxation effects [2], [15], [16]) that can be used for all air conditions (temperature and humidity). This is particularly important when simulating partly-outdoor spaces, such as, e.g., medieval cathedrals [17] or other heritage/historic sites [18]- [21]. The general aim of the proposed method is to use an input signal to drive a set of exponentially-damped plane waves, which travel a given distance such that the resulting output can be seen as frequency-and distance-based air attenuation having been applied to the input signal.…”

Adding air attenuation to simulated room impulse responses: A modal approach

Preprint

View full text Add to dashboard Cite

Air absorption is an important effect to consider when simulating room acoustics as it leads to significant attenuation in high frequencies. In this study, an offline method for adding air absorption to simulated room impulse responses is devised. The proposed method is based on a modal scheme for a system of one-dimensional dissipative wave equations, which can be used to post-process a room impulse response simulated without air absorption, thereby incorporating missing frequencydependent distance-based air attenuation. Numerical examples are presented to evaluate the proposed method, along with comparisons to existing filter-based methods.
