Technical and design capabilites

DASM is the leading of development in the acoustic materials industry. We are committed to pioneering research and development in the field of acoustics and acoustics materials. Futhermore, we also have employed significant time, energy and resources into ongoing development of our in-house tools and specialized equipment imported from abroad. As a result, DASM can satisfy all needs and wants of customers – serving across a range of sectors including concert halls, theatre design, building acoustics, environmental noise modelling, intelligent noise loggers, underwater acoustics and more. 

Our service is a unique combination of design skills, research knowledge and predictive techniques to provide effective solutions meeting customer needs. Our acoustic measurement tools including the facility to carry out computer modelling and also scale model testing on small-scale physical models.

What can we do?


DASM employs sophisticated measurement equipment, the most up-to-date acoustic collection of audio data, analysis software and complex visualization tools to identify and optimize existing acoutical systems with conditions in the time and frequency domain, including reverberation times (RT60), transmission attenuation (Transmission Loss), speech transmission index (Speech Intelligibility Assessments), sound pressure level (Sound Pressure Level – SPL), background noise levels (Background Noise Levels) and many other parameters.

Our engineering team specializes in collecting critical measurement data in-situ or in laboratories to establish, finalize/provide documentation to customers. This work applies to both technical design, legal purposes and presents useful interpretations of measurement results and their consequences. All work coplies to the latest international, industry standards and professional compliance values.


DASM uses sophisticated prediction and analysis software to model and study the behavior of sound in three-dimensional virtual space.

Be a pioneer in using acoustical modeling tools and auralization by using the industry’s most advanced acoustic modeling and prediction software. We model environment using an iterative process.

These software tools facilitate “auralization” – a complex calculated algorithm that allows for input of an original, nonprocessed audio file data (such as speech announcements or acoustical instrumental recordings). An then renders an audible reproduction of the future acoustical situation in the virtual building environment. This allows all stakeholders to listen to music,speech or ant audio content in the virtual design reality. The obtained results provide invaluable tools for design and planning, as well as more realistic sound reproduction based on changing source environments.


Room Acoustics is the science of controlling a room’s internal acoustic properties by creating geometries in combination with creative surfaces materialization using reflection, absorption and/or diffusion. Excessive reverberation time can lead to poor speech intelligibility, high ambient noise levels, poor ability to concentrate and limited comfort, especially in workplaces and security/privacy applications. Interior acoustic floor, wall, and ceiling surfaces can be created sing a qide variety of materials and finishes, including perforated, slotted, fabric coverd, foam based, plastic, wood, glass, metal or gymsum materialization.

DASM carefully studies and specifies appropriate materials and applications, always with a keen eye and respect for a project’s underlying architecture.


Architectural acoustics analyzes the transmission of noise from building exterior envelope to interior and vice versa, as well as noise transmission from one room to another within the building environment.

Inadequate sound insulation can lead to elevated sound levels within the space with the following consequences: reduce privacy, comfort and concentration ability; severely limit speech intelligibility and has an impact/affect on health.
The main noise path usually includes roofs, ceilings, eaves, walls, windows, doors, room partitions, as well as flanking, ducting and other penetration lines.
Sufficient noise containment control will ensure optimum functionality of the space and is often required by local municipal codes. Specifications from DASM include construction details for wall and slab assemblies and special acoustical isolation conditions.


DASM is a trusted partner for Peer Review, Expert Reports, Researches and Surveys in the field of architectural acoustics consultation.

Peer review is the evaluation of work and researches done by other parties. This work is often required to maintain quality standards:

Assess solutions and designs

Providing a second opinion or variations to a concept

Create alternative solutions to improve performance and efficiency

Provide reliability

Verify costing and timetable analysis

All DASM’s researches and surveys are often based on in-situ or laboratory measurements, assessments utilizing a variety of international benchmarks and standards.
