In the case of the Sri Vidya Temple in Rush, NY, a recent change from carpeted to tiled flooring significantly increased the reverberation time within the main hall\u2014a medium-sized space primarily used for religious ceremonies. These events involve a central fire pit and require continuous ventilation, both of which contribute additional acoustic challenges. This project aimed to reduce sound reflections and enhance clarity, with specific targets for reverberation time and clarity (C50 and C80) to support both speech and music. A custom solution was developed and implemented using several sets of DIY acoustic panels, designed with fire safety, portability, cost, and visual integration with the temple interior in mind. A prototype was constructed and evaluated in the space to assess its real-world performance.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-barlow-condensed-font-family has-custom-font\" style=\"font-family: Barlow Condensed; font-size: 30px;\"><strong>Design Objectives<\/strong><\/p>\r\n\r\n\r\n\r\n<p class=\"has-helvetica-font-family has-custom-font\" style=\"font-family: Helvetica;\">The primary goal was to design, implement, and verify an acoustic treatment considering the constraints of the space:<\/p>\r\n\r\n\r\n\r\n<ol class=\"wp-block-list has-helvetica-font-family has-custom-font\" style=\"font-family: Helvetica;\">\r\n<li>The treatment must not interfere with any religious visuals in the space\u00a0<\/li>\r\n\r\n\r\n\r\n<li>The treatment must be fire resistant and\/or fire proof due to daily indoor fire-related activities\u00a0<\/li>\r\n\r\n\r\n\r\n<li>The treatment must be easy to clean significant smoke damage\u00a0<\/li>\r\n\r\n\r\n\r\n<li>The treatment must be compatible with the in-house PA system\u00a0<\/li>\r\n\r\n\r\n\r\n<li>The cost of the treatment must be within the prescribed budget\u00a0<\/li>\r\n\r\n\r\n\r\n<li>The space is used for both speech and music, so the acoustics must accommodate both use cases<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<p class=\"has-barlow-condensed-font-family has-custom-font\" style=\"font-family: Barlow Condensed; font-size: 30px;\"><strong>Method<\/strong><\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-align-center has-barlow-condensed-font-family has-custom-font\" style=\"font-family: 'Barlow Condensed'; font-size: 26px; text-align: center;\"><em>1 Measurement<\/em><\/p>\r\n\r\n\r\n\r\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\r\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\r\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\r\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-194232\" src=\"https:\/\/www.hajim.rochester.edu\/senior-design-day\/wp-content\/uploads\/2025\/04\/Screenshot-2025-04-30-at-4.20.03\u202fPM-1-1024x885-1.png\" alt=\"\" width=\"606\" height=\"524\" srcset=\"https:\/\/www.hajim.rochester.edu\/senior-design-day\/wp-content\/uploads\/2025\/04\/Screenshot-2025-04-30-at-4.20.03\u202fPM-1-1024x885-1.png 1024w, https:\/\/www.hajim.rochester.edu\/senior-design-day\/wp-content\/uploads\/2025\/04\/Screenshot-2025-04-30-at-4.20.03\u202fPM-1-1024x885-1-300x259.png 300w, https:\/\/www.hajim.rochester.edu\/senior-design-day\/wp-content\/uploads\/2025\/04\/Screenshot-2025-04-30-at-4.20.03\u202fPM-1-1024x885-1-768x664.png 768w\" sizes=\"auto, (max-width: 606px) 100vw, 606px\" \/><\/figure>\r\n<\/div>\r\n\r\n\r\n\r\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\r\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-194242\" src=\"https:\/\/www.hajim.rochester.edu\/senior-design-day\/wp-content\/uploads\/2025\/04\/Screenshot-2025-04-30-at-4.21.59\u202fPM-2-1024x985-1.png\" alt=\"\" width=\"591\" height=\"569\" srcset=\"https:\/\/www.hajim.rochester.edu\/senior-design-day\/wp-content\/uploads\/2025\/04\/Screenshot-2025-04-30-at-4.21.59\u202fPM-2-1024x985-1.png 1024w, https:\/\/www.hajim.rochester.edu\/senior-design-day\/wp-content\/uploads\/2025\/04\/Screenshot-2025-04-30-at-4.21.59\u202fPM-2-1024x985-1-300x289.png 300w, https:\/\/www.hajim.rochester.edu\/senior-design-day\/wp-content\/uploads\/2025\/04\/Screenshot-2025-04-30-at-4.21.59\u202fPM-2-1024x985-1-768x739.png 768w\" sizes=\"auto, (max-width: 591px) 100vw, 591px\" \/><\/figure>\r\n<\/div>\r\n<\/div>\r\n<\/div><\/div>\r\n\r\n\r\n\r\n<p class=\"has-helvetica-font-family has-custom-font\" style=\"font-family: Helvetica;\">Architectural measurements were taken to develop an accurate floor plan of the main hall.

The initial panels experienced significant drooping at the joining points, which was corrected by shortening their length and using additional carabiner rings for a tighter suspension.

Existing ceiling hooks in the temple were used, and the panels can be easily attached using carabiners.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-helvetica-font-family has-custom-font\" style=\"font-family: Helvetica;\"><strong>Manual<\/strong>: To support future expansion, we created a step-by-step DIY manual for constructing the panels.

Our simulations were based on a full 22-panel configuration, and the temple has the option to construct the remaining 10 panels using our guide. Additionally, the outer fabric can be customized with velcro, allowing the temple to change colors or patterns to match the space. This outer layer can also be removed for cleaning, extending the longevity of the panels and maintaining their performance in a smoke-prone environment.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-text-align-center has-helvetica-font-family has-custom-font\" style=\"font-family: Helvetica;\"><em>(Finalized manual will be uploaded soon)<\/em><\/p>\r\n","protected":false},"excerpt":{"rendered":"<p>Team Members Yunji Kim &#8211; B.S.
