Methods and solutions offered
Our acoustic testing approach combines precision measurement with practical application. We measure sound absorption by determining decay rates in reverberation chambers, while transmission loss is evaluated through carefully calibrated test chambers. These controlled environments allow us to isolate and accurately quantify the acoustic properties that matter most for your application.

• Reverberation chamber testing for sound absorption
• Laboratory measurement of airborne sound transmission loss
• On-site analysis of wall, ceiling, and floor assemblies
• Evaluation of sound insulating properties
• Impact sound isolation measurement between rooms

We offer the following methods and solutions as part of our acoustic testing services:

Sound Absorption Testing
Sound absorption testing evaluates how well building materials reduce reflected sound and lower noise levels. Our tests follow ASTM C423, E795, and ISO 354 standards. At our A2LA-accredited facility, our architectural acoustics experts use advanced reverberation chambers to assess the performance of various absorption materials. We measure sound absorption by analyzing the decay rate in a reverberation room. Each material receives two ratings:

• Noise Reduction Coefficient (NRC): An average of sound absorption coefficients at 250, 500, 1000, and 2000 Hz, rounded to the nearest multiple of 0.05.
• Sound Absorption Average (SAA): A single-number rating that considers absorption coefficients from 200 to 2500 Hz, providing a more detailed measure of a material’s sound absorption capabilities.

Sound Transmission Loss Testing
Sound transmission loss testing measures how well building materials block sound. Our testing follows ASTM E90, E423, E1332, AAMA 1801, and ISO 10140 standards. We assess the airborne sound transmission loss of building elements and partitions and use two key ratings to evaluate sound transmission loss:

• Sound Transmission Class (STC): A single-number rating based on transmission loss (TL) values, estimating how effectively a partition blocks sound.
• Outdoor/Indoor Transmission Class (OITC): A rating that measures how well a material reduces noise from planes, trains, and cars, particularly for building facades and facade elements like windows and doors.

Field Testing
Beyond laboratory testing, we offer on-site analysis of wall, ceiling, and floor assemblies to evaluate real-world acoustical performance. These tests adhere to ASTM E336 and E1007 standards. Our field testing measures:

• Airborne sound insulation of walls, ceilings, and floors
• Impact sound isolation between rooms
• These services help architects, building officials, and contractors ensure compliance with building code requirements.

Extended acoustic testing capabilities
Beyond ¹ú²ú͵ÅÄ×ÔÅÄ's acoustic testing services, we are able to offer additional specialized testing through our sister company, Warringtonfire. Their laboratory provides sound insulation performance testing up to 58dB (Rw) or 73dB (Rw) according to BS EN ISO 10140 series standards for a wide range of building elements including door sets, windows, glazing systems, and partition systems. This extended capability ensures you can access comprehensive acoustic performance evaluation for virtually any building component through the ¹ú²ú͵ÅÄ×ÔÅÄ family of companies.

Acoustic Design Review Services
Via Al Futtaim ¹ú²ú͵ÅÄ×ÔÅÄ, our team offers Acoustic Design Review services to ensure optimal sound quality, regulatory compliance, and user comfort across all building types. We provide expert-led design and material reviews that prevent costly issues and enhance acoustic performance. Our team supports every stage of the project lifecycle, from concept to construction, while ensuring alignment with the UAE Federal Building Code, Al Sa’fat Green Building System, and international standards. Whether for commercial, residential, or mixed-use projects, we create environments where sound is a benefit, not a barrier.
