Summary
This study measured acoustic properties in 12 Mudejar-Gothic churches in Seville, revealing variations in sound quality despite similar architecture. Findings inform architectural acoustics and space suitability for music and speech.
Area of Science:
- Architectural Acoustics
- Building Physics
- Environmental Acoustics
Background:
- 12 Mudejar-Gothic churches in Seville, Spain, with varying volumes (3947–10,708 m³), were studied.
- Despite a common architectural style, individual characteristics influence acoustic performance.
Purpose of the Study:
- To measure and analyze key acoustic parameters within these unique historical spaces.
- To assess the suitability of these churches for musical performances and speech intelligibility.
- To compare experimental results with theoretical models in architectural acoustics.
Main Methods:
- Acoustic measurements were conducted in unoccupied churches following ISO-3382 standards.
- Impulse response analysis using a maximum length sequence system was employed.
- Parameters measured included reverberation times, sound strength, early-to-late sound energy metrics, and speech intelligibility (Rapid Speech Transmission Index).
- Background noise levels were measured to determine Noise Rating (NR) indices.
Main Results:
- Detailed acoustic fields were characterized for each church.
- Variations in reverberation, sound distribution, and speech intelligibility were observed.
- Analysis provided insights into the acoustic quality for music and speech based on established criteria.
Conclusions:
- The study provides a comprehensive acoustic assessment of Mudejar-Gothic churches in Seville.
- Results highlight the impact of architectural specifics on acoustic outcomes.
- Findings contribute to understanding the acoustic behavior of historical religious buildings for diverse uses.
