DASM Sound Transmission Class (STC) Testing of Movable Partitions at the Vin Co Loa Conference & Event Center (VinPalace)

DASM Institute – Vietnam's leading organization in measurement, testing and acoustic consulting – has measured the sound transmission class (STC) of the movable partition system at the Vin Co Loa Conference & Event Center (VinPalace). DASM applies ISO 16283 & ISO 717 to ensure accuracy, transparency and high technical value.

The role of sound insulation testing in large-scale projects

As conference, exhibition and premium event center projects receive ever more systematic investment in engineering and spatial experience, sound insulation performance has become one of the most important factors in assessing construction quality.

A partition system, especially a movable partition made of sound insulation materials and sound absorption materials, must not only be flexible in use but also deliver optimal sound insulation, preventing noise transmission between areas and ensuring privacy and sound quality inside each space.

For this reason, measuring the sound transmission class (STC) is an indispensable step in the acceptance and construction quality assessment of large-scale projects.

DASM – A pioneer in acoustic measurement and testing in Vietnam

The Institute for Development and Application of Acoustic Materials (DASM) is the first organization in Vietnam to be certified by the Bureau of Accreditation (BoA) as a VILAS-accredited laboratory, in accordance with international standards on technical competence and quality management systems.

This means that all acoustic measurements, tests and services performed by DASM meet international standards, with recognized accuracy and reliability.

Furthermore, DASM is a regular partner of many general contractors, design consultants and major investors nationwide, having carried out hundreds of measurement and testing projects on sound insulation, sound absorption and noise and vibration for conference centers, theaters, 5-star hotels, commercial complexes, industrial plants and specialized studios.

STC measurement project for the movable partition system at the Vin Co Loa Conference & Event Center (VinPalace)

Recently, DASM was selected to measure the sound transmission class (STC) of the movable partition system at the Vin Co Loa Conference & Event Center (VinPalace), one of the largest and most modern conference and exhibition complexes in Vietnam today.

This is a project with high technical requirements, in which movable partitions are used to flexibly divide the space between event, conference and exhibition areas.

The STC measurement was carried out by DASM directly on site, using modern acoustic measuring equipment calibrated periodically to international standards, ensuring the accuracy and transparency of the entire process.

Furthermore, the measurements were carried out in strict accordance with the 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 faithfully reflect the actual sound insulation performance of the building, but also serve as a reliable technical basis for the parties involved – from contractors and consultants to investors – to use in acceptance, assessment and improvement of construction quality.

ISO 16283 and ISO 717 standards – International assurance of measurement quality

In building acoustics, the ISO 16283 and ISO 717 series are regarded as the most important technical foundations for evaluating the sound insulation performance of structures such as walls, partitions, doors, floors and ceilings.

ISO 16283 specifies the field measurement method (Field Testing) – accurately simulating real conditions of use and precisely reflecting the ability to block sound transmission between two spaces.

ISO 717, in turn, provides the method for rating and expressing results, converting measurement data into standardized indices such as STC (Sound Transmission Class), making it easy to compare against design requirements.

DASM's simultaneous application of both standards during measurement demonstrates professionalism, adherence to standards and technical capability at an international level, helping to raise the reputation of Vietnam's acoustics industry.

Professional measurement procedure – Accuracy in every detail

To ensure highly reliable measurement results, DASM follows a rigorous and consistent working procedure:

+ On-site survey to determine the partition configuration, spatial conditions and a suitable sound source.

+ Installing specialized measuring equipment, including a standard sound source loudspeaker, sound pressure microphones, a signal analyzer and a calibration system.

+ Measuring at multiple frequencies, simulating real sound bands during use.

+ Analyzing results with specialized software, calculating the STC value and comparing it with the design standard.

+ Preparing a detailed technical report, including data, graphs, measurement photos and professional comments.

In addition, DASM's team of acoustic experts has many years of practical experience in on-site measurement, ensuring that implementation is safe, accurate and on schedule.

Benefits of measuring the sound transmission class (STC) in construction projects

STC measurement brings many clear benefits to investors and contractors, including:

Noise survey and assessment, accurately evaluating the actual sound insulation performance rather than relying only on theoretical calculations.

Identifying technical defects or sound leakage points, helping to improve construction quality.

Ensuring the project meets international acoustic standards, enhancing brand value and credibility.

Providing transparent technical certification for acceptance, handover or independent inspection.

As a result, sound insulation measurement by DASM is not only a technical service but also a solution that ensures the overall quality of modern buildings.

DASM – A trusted partner of Vietnam's leading contractors and investors

With extensive experience, modern equipment, international measurement standards and a team of highly qualified acoustic engineers, DASM has become a strategic partner of many major domestic and international general contractors.

From conference centers, theaters and high-end hotels to industrial plants, recording rooms, studios and shopping centers, DASM is consistently highly regarded for its accuracy, responsiveness and professionalism in every project.

Beyond measurement, DASM also provides acoustic consulting and design for buildings, noise and vibration control, acoustic simulation design, etc., helping customers optimize sound insulation, sound absorption and noise control from the initial design stage.

DASM's STC measurement of the movable partition system at the Vin Co Loa Conference & Event Center (VinPalace) is not only proof of DASM's professional capability and reputation, but also shows the progress of Vietnam's acoustics industry in approaching international standards.
