Dr. Dung praised the students’ enthusiasm for research and their excellent performance throughout the program. Meanwhile, team leader Le Ngoc Bon excitedly shared:
“DASM offers a highly professional and modern working environment. The institute is equipped with state-of-the-art facilities and advanced machinery, making it the most well-equipped acoustic research institution in Vietnam today. We are truly fortunate and honored to have received such dedicated and thorough guidance from Dr. Vu Viet Dung. Although our internship was brief, it provided us with invaluable knowledge and experience in acoustics. We successfully built an acoustic camera, a product that will significantly benefit our field of study. We believe DASM is the ideal destination for students and researchers interested in acoustics. Personally, I am very satisfied with what I have learned and hope to continue collaborating with DASM in the future!”

An acoustic camera is a mobile system designed to visualize sound and its sources. It generates sound source maps resembling thermal images within seconds, allowing for rapid localization and analysis of noise sources based on various criteria. The primary goal of the acoustic camera is to enable real-time sound visualization, accurately determining the location of noise sources in space and measuring their intensity.
In Aeronautical Engineering, this technology is particularly useful for identifying noise sources in aircraft engines or measuring noise levels at airports. It aids in noise reduction and mitigation efforts, improving both efficiency and environmental impact.

Reflecting on the internship program and its outcomes, Dr. Dinh Cong Truong commented:
“I sincerely appreciate the leadership and senior experts at DASM for providing such an excellent opportunity for our students. I closely monitored their progress and am highly satisfied with the results. A scientific committee will soon evaluate their work and assign graduation grades accordingly. I also plan to discuss potential collaborations with other research groups at HUST to further strengthen ties between our university and DASM. In the near future, I will be leading multiple research projects and experimental studies related to noise control, and DASM will undoubtedly be my trusted partner in these endeavors.”
Since its establishment, DASM has become a premier destination for students, research groups, and leading technical universities in Vietnam to explore and study acoustics. The collaboration between universities, DASM, and enterprises plays a crucial role in advancing scientific research and technology development. It facilitates the transfer of research findings into practical applications, optimizing production processes and product quality, while also fostering professional training and elevating Vietnamese intellectual contributions on the global stage.
