A Case Study Acoustic Design for a Hotel Bar
LE 313.00
This case study investigates the acoustic design of a bar in a hotel to minimize noise emission to neighboring areas and guest rooms. Noise level measurements were conducted on-site to assess the bar's noise emission and its impact on the surrounding environment. The main goals were to reduce noise emission, especially low-frequency emissions, minimize current complaints from nearby residences, and achieve good acoustic performance inside the bar in terms of reverberation time (RT) and noise criteria (NC). The design aimed to find a practical and visible solution using proper wall damping systems, considering the availability of materials in the Egyptian market. Challenges faced during the project included reducing noise escape from the night club at a low cost, optimizing speaker locations for even sound distribution and less structural vibration, and addressing sound escape through ducts. The design guidelines included reviewing the HVAC system, ensuring no penetration from the ceiling to the bar, and meeting sound transmission class (STC) requirements for walls. The relationship between STC and sound reduction index (R'w) was also discussed. The study highlights the importance of considering flanking sound transmission in addition to direct sound transmission through partition assemblies to achieve effective noise reduction in buildings.
