Acoustic study and comparison of the behavior of different models of sound-absorbing plates in noise reduction in the new passenger terminal of Ahwaz International Airport
Abstract: The interior of airport lounges is often exposed to a lot of noise, which can increase the risk to human health. Due to the dangers of high noise pollution for airport users, the present study was conducted to reduce noise pollution in the transit lounges of Ahvaz International Airport. Ba...

| description | Abstract: The interior of airport lounges is often exposed to a lot of noise, which can increase the risk to human health. Due to the dangers of high noise pollution for airport users, the present study was conducted to reduce noise pollution in the transit lounges of Ahvaz International Airport. Background and Aim: This study is considered interdisciplinary and applied research and its method is a combination of experimental, simulation and case study methods. firstly, the acoustic status of Ahwaz International Airport was obtained experimentally by measuring the amount of noise pollution during the test period (8 AM to 2 PM) by the Brüel & Kjær sound level meter model 2260 B&K in twelve places. Then the sound absorbing plates were tested with different geometric models. After proving the validity and reliability of the research, the experiments were performed by simulation using EASE 4.4 software. Materials and methods: In this study, the noise level of the airport lounge is considered as a dependent variable and four sound indices including, reverberation time (RT) (main index), indirect sound index (STI), total sound pressure level (SPL) and auditory error coefficient (〖AL〗_CONSE ) were evaluated according to the international standards ISO3382 and ISO 3382-1. Results: After the simulation, it was found that the use of raster pattern sound-absorbing plates (Model A in research) in walls and ceilings with different frequencies has the lowest sound pressure and the above-studied indices are at a desirable level. As a result, Model A has the greatest effect on reducing noise in the tested space. |
