MATERIALS ACOUSTIC TEST

The Institute of development and application for sound materials (DASM) has just registered testing activities in the field of physical mechanics with the Directorate for Standards, Metrology and Quality (Ministry of Science & Technology).

With a team of highly experienced acoustic specialists, DASM offers professional acoustic testing services that strictly adhere to international standards. Our services provide clients with accurate and efficient solutions for acoustic testing, measurement, surveys, evaluations, and consultancy.

DASM leverages state-of-the-art measurement equipment, the latest acoustic data collection systems, advanced analysis software, and complex visualization tools to identify and optimize sound systems across time and frequency domains. Our expertise covers key acoustic parameters, including: Reverberation Time (RT60), Transmission Loss (TL), Speech Intelligibility Index (STI), Sound Pressure Level (SPL), Background Noise Level (BNL) and various other essential acoustic metrics.

Our team of engineers conducts critical field and laboratory measurements, providing clients with comprehensive documentation for technical design, legal purposes, or reporting. We deliver clear, insightful interpretations of measurement results and their implications, tailored to meet each client’s specific needs. All testing and evaluation processes are conducted in strict compliance with international standards, industry regulations, and the latest professional guidelines to ensure reliability, accuracy, and transparency.
