Choosing the Institute for Development & Application of Sound Materials (DASM) for acoustic consulting services means collaborating with a team of elite, professional experts in sound performance and noise control design for architecture and construction. We provide leading technical solutions and products aimed at achieving optimal and distinctive results.
Acoustics – The key to success for many buildings & construction spaces
Acoustics are a key to success for many buildings, constructions, and spaces. Most of us have dined in a noisy restaurant unable to hear the words of a friend sitting across from us, or tried to study in a library filled with distracting noises. Today’s workplace often features open-space designs, but did you know this can actually contribute to noise and potentially affect employees’ ability to concentrate and their productivity?
The Institute for Development & Application of Sound Materials (DASM) collaborates with architects and engineers across many projects for acoustic consulting and noise control, from the simplest soundproofing tasks to the most complex challenges of noise reduction in buildings. We help create effective operating environments where users feel enjoyable and comfortable. Our team of sound engineering consultants at DASM designs spaces to optimize listening conditions, noise control, and privacy. When needed, we use sound simulation technology to allow clients to “hear” their spaces before they are built. Our equipment laboratory is equipped with state-of-the-art tools for measuring, monitoring, and analyzing sound.
DASM is ready to provide acoustic consulting services wherever clients need, both indoors and outdoors. In crowded urban environments where noise-sensitive neighbors may be close by; in rural areas where the surrounding sounds are the wind or the ocean waves. Our consulting experts advise on both new construction and renovation projects. DASM’s scope includes world-class performance spaces, workplaces requiring sound privacy, laboratories with complex noise control requirements, and classrooms that require quiet for clear communication.
ACOUSTIC CONSULTING AND DESIGN
Room Acoustics Design, Analysis & Surface Treatment
Room Acoustics is the science of controlling a room’s internal sound characteristics through creative geometry and surface material combinations using reflection, absorption, and/or diffusion. Excessive reverberation can lead to poor speech intelligibility – reduced focus, high ambient noise levels, and limited comfort, especially in workplaces and private/security applications.
Interior floor, wall, and ceiling surfaces can be created using various materials and finishes including perforated, grooved, fabric-covered, foam, plastic, wood, glass, metal, or gypsum.
DASM meticulously researches and specifies materials and applications with keen insight and respect for the basic architecture of the project.
Achieving satisfying sound results is both a complex and subtle process, in which elements like shape, size, building materials, or furniture of the space play an extremely important role. In spaces for music reproduction, auditoriums, performing arts, recording, and post-production, the results are even more noteworthy.
How high should ceilings be? What sound-absorbing materials are needed? How to accurately and reasonably combine different materials for thorough soundproofing? Should soundproofing and sound barriers be achieved by building high walls to the ceiling instead of to an acoustically treated ceiling?… etc. DASM uses the most advanced software for simulating site sound and sound, as well as other specialized tools to design and calculate acoustic parameters… – the most convincing answers to the above questions.
Architectural Acoustics: Soundproofing, Analysis, and Design
Architectural acoustics involves analyzing noise transmission from the exterior building envelope to interior spaces and vice versa, as well as noise transmission between rooms within a building environment. Insufficient soundproofing can result in high noise levels, leading to reduced privacy, comfort, and focus, impaired speech intelligibility, and potential health impacts.
Key noise pathways typically include roofs, ceilings, eaves, walls, windows, doors, partitions, as well as building frameworks, ducts, and other penetrations. Walls, floors/ceilings, windows, doors, and other building components regulate sound transmission between internal spaces and from inside to outside. DASM works closely with design teams to detail building assemblies that ensure appropriate acoustic separation. This includes tailoring soundproofing solutions to meet specific needs, along with controlling noise and vibrations from mechanical installations like HVAC systems or lighting.
Our team designs custom acoustic solutions for each project, addressing both building system levels and interior sound treatment.
Comprehensive noise control measures not only optimize space functionality but are often mandated by local laws and regulations. DASM provides technical guidance, including detailed system specifications for wall and floor assemblies and specialized soundproofing conditions.
Mechanical Noise and Vibration Control
Achieving the appropriate background noise levels tailored to the intended purpose of a space requires effective noise and vibration control from a building’s mechanical, electrical, and plumbing systems.
- Want to hear every note from musicians and performers?
- Need to understand every word from guest speakers or lecturers?
Simply put, mechanical noise control is critical to ensuring optimal performance in these settings.
DASM’s Acoustic Design Process
We leverage scientific and technical expertise to demystify acoustics. Each project begins with identifying client-specific needs, followed by a scientific, reliable design process.
Phase 1:
✓ On-site or remote measurements and 3D room modeling
✓ Acoustic testing to capture RT60, frequency response, waterfall charts, etc.
✓ Data measurement and testing analysis
Phase 2:
✓ Initial design development
✓ Client review and revisions
✓ Installation of acoustic treatments
Phase 3:
✓ Additional acoustic testing to obtain RT60, frequency response, waterfall charts, etc.
✓ Analyzing measurements and test data to identify further needs
✓ Design modifications and enhancements (if required).
At DASM, we don’t just research, innovate, and enhance materials/products. We also design and deliver tailored acoustic solutions for each project.
DASM exists to provide reliable, insightful, and accessible acoustic designs for all. This commitment has made us a leading consultant in Vietnam, delivering innovative architectural and acoustic solutions.
