DASM Institute – a leading unit in Vietnam in the field of measurement, testing and acoustic consulting – performed sound insulation coefficient (STC) measurements for the movable partition system at the Vin Co Loa Convention and Event Center (VinPalace). DASM applies ISO 16283 & ISO 717 standards, ensuring high accuracy, transparency, and technical value.

The role of sound insulation measurement in large-scale projects
In the context of high-end convention, exhibition, and event center projects receiving substantial investment in technical aspects and spatial experience, sound insulation performance becomes one of the most critical factors for evaluating construction quality.
A partition system, especially a movable partition constructed from sound insulation materials and sound absorption materials, not only needs to ensure flexibility in use but also must achieve optimal sound insulation performance, helping to prevent noise transmission between areas, ensuring privacy and sound quality within each space.
Therefore, measuring the sound insulation coefficient (STC) is an indispensable step in the handover and evaluation of construction quality for large-scale projects.
DASM – A pioneer in the field of acoustic measurement and testing in Vietnam
The DASM Institute for Development & Application of Acoustic Materials is the first unit in Vietnam to be granted VILAS laboratory accreditation by the Bureau of Accreditation (BoA), in accordance with international standards on technical competence and quality management systems.dat chuan VILAS, theo cac tieu chuan quoc te ve nang luc ky thuat va he thong quan ly chat luong.
This means that all acoustic measurements, tests, services conducted by DASM meet international standards, recognized for their accuracy and reliability.
Furthermore, DASM is a regular partner of many general contractors, design consultants, and major investors nationwide, carrying out hundreds of projects measuring and testing sound insulation, sound absorption, and noise-vibration for facilities such as convention centers, theaters, 5-star hotels, commercial areas, industrial plants, and specialized studios.

STC sound insulation coefficient measurement project for the movable partition system at the Vin Co Loa Convention and Event Center (VinPalace)
Recently, DASM was selected to perform sound insulation coefficient (STC) measurements for the movable partition system at the Vin Co Loa Convention and Event Center (VinPalace), one of the largest and most modern convention and exhibition complexes in Vietnam today.
This is a project with high technical requirements, where movable partitions are used to flexibly divide space between event, convention, and exhibition areas.
The STC measurement was conducted directly on-site by DASM using modern acoustic equipment, periodically calibrated according to international standards, ensuring the accuracy and transparency of the entire process.
Furthermore, the measurements were conducted in strict compliance with international technical procedures ISO 16283 (Field Measurement of Sound Insulation in Buildings and of Building Elements) and ISO 717 (Rating of Sound Insulation in Buildings and of Building Elements).
As a result, DASM's measurement results not only accurately reflect the actual sound insulation performance of the project but also serve as a reliable technical basis for stakeholders – from contractors and consultants to investors – to use in handover, evaluation, and construction quality improvement.

ISO 16283 and ISO 717 standards – International endorsement for measurement quality
In the field of building acoustics, the two sets of standards ISO 16283 and ISO 717 are considered the most important technical foundations for evaluating the sound insulation performance of structures such as walls, partitions, doors, floors, and ceilings.
ISO 16283 specifies field testing methods – simulating actual operating conditions, accurately reflecting sound transmission loss between two spaces.
ISO 717 provides evaluation and expression methods for results, converting measurement data into standardized indices such as STC (Sound Transmission Class), facilitating easy comparison and alignment with design requirements.
The fact that DASM applies both of these standards simultaneously during the measurement process demonstrates professionalism, standardization, and international-level technical capacity, contributing to enhancing the reputation of Vietnam's acoustics industry.
Professional measurement process – Precision in every detail
To ensure high reliability of measurement results, DASM adheres to a strict and consistent workflow:
+ Conduct on-site surveys to determine the wall configuration, spatial conditions, and appropriate sound sources.
+ Installation of specialized measuring equipment, including standard sound sources, sound pressure level measuring microphones, signal analyzers, and calibration systems.
+ Conducting measurements at various frequencies, simulating actual sound ranges during use.
+ Analyzing results using specialized software, calculating STC values, and comparing them with design standards.
+ Preparing detailed technical reports, including data, charts, measurement images, and professional comments.
In addition, DASM's team of acoustic experts all have years of practical experience in on-site measurements, ensuring safe, accurate, and on-schedule implementation.

Benefits of measuring the sound insulation coefficient (STC) in construction projects
Performing STC measurements brings clear benefits to investors and contractors, including:
Noise survey and assessment, accurately evaluating actual sound insulation performance rather than relying solely on theoretical calculations.
Identifying technical errors or sound leakage points, helping to improve construction quality.
Ensure that the project meets international acoustic standards, enhancing brand value and reliability.
Provide transparent technical certification to serve acceptance testing, handover, or independent inspection.
As a result, conducting sound insulation testing by DASM is not only a technical service, but also a comprehensive quality assurance solution for modern construction.
DASM – A reliable partner of leading contractors and investors in Vietnam
With extensive experience, modern equipment systems, international measurement standards, and a team of highly qualified acoustic engineers, DASM has become a strategic partner for many major domestic and international general contractors.
From convention centers, theaters, high-end hotels to industrial plants, recording studios, and commercial centers, DASM is always highly evaluated for accuracy, response speed, and professionalism in every project.
Not only performing measurements, DASM also provides consulting and acoustic design services for buildings, noise and vibration control, acoustic simulation design, etc., helping clients optimize sound insulation, sound absorption, and noise control right from the initial design stage.
The event where DASM performed sound transmission class (STC) testing for movable partition walls at the Vin Co Loa Convention & Event Center (VinPalace) is not only proof of DASM's professional capacity and reputation, but also demonstrates a step forward for Vietnam's acoustics industry in approaching international standards.
