Laboratory measurement of airborne sound insulation of door leaves and door assemblies

Laboratory measurement of sound transmission loss of door panels and door systems for the purpose of measuring and determining sound transmission loss for door panels and door systems; calculating and designing effective acoustic rooms…

Overview of the Laboratory measurement of sound transmission loss of door panels and door systems

Test name: Standard Test Method for Laboratory Measurement of the Sound Transmission Loss of Door Panels and Door Systems.

Test method: ASTM E1408-2000: Standard Test Method for Laboratory Measurement of the Sound Transmission Loss of Door Panels and Door Systems [1].

Performed at: Laboratory, Institute of Acoustics and Sound Materials (DASM).

1. Objectives and test subjects

– Test objectives

This test method describes the laboratory measurement of sound transmission loss for door panels and door systems. It also covers the measurement of forces required to close and latch, as well as unlatch the door being tested.  

– Test subjects

• Door panels
• Door systems

2. Experimental procedure

Steps to perform:

• Equip fully with devices, microphones, and test subjects.
• The laboratory ensures a volume of 200m³.
• Perform sample measurement.
• Process and report results.

Test sample description:

+ Description must include information on the door panel, frame, and hardware. Information on the door panel shall include model number, material, dimensions, weight, and other relevant physical properties. Average surface mass (of the door panel) may be reported if applicable to the design.

+ Information on the frame shall include material and installation procedures including whether the frame is hollow or packed.

+ Hardware information shall include a full description of all latching and unlatching hardware components. Whenever possible, the testing laboratory should observe and report the materials, dimensions, mass, and relevant physical properties of the main components and how they are assembled, including a description of fastening elements. Detailed drawings should be provided by the manufacturer.

+ A designation/description provided by the sponsor may be included in the report providing information attributed directly to the sponsor. Curing time, if any, and the final condition of the test specimen (shrinkage, cracking, etc.) shall be reported.

3. Notes on measurement samples

Remove the lockset and seal the lockset holes (both sides). Use minimum material sealing and do not fill the internal cavity of the lockset. Remove the door hinges and seal their corresponding mounting holes. The door panel should be reinstalled with the same peripheral clearance between it and the test frame structure as was used for feasible tests. Rigid spacers of appropriate thickness should be placed under the two lower door corners.

To minimize added mass, these spacers shall be no more than 6.35mm (0.25 inches) wide. 

Role – Importance of the Laboratory measurement of sound transmission loss of door panels and door systems

The Laboratory measurement of sound transmission loss of door panels and door systems performed by the Institute of Acoustics and Sound Materials helps provide useful information, meeting all practical needs of customers and businesses wishing to:

• Measure and determine: sound transmission loss of operable doors equipped with combined hardware and seals; sound transmission loss of sealed door panels in the laboratory; force or torque required to operate the door system.
• Evaluate the overall sound transmission loss reduction level of an operable door system, which may include various sealing parts and hardware.
• Determine the respective contribution of door components and seals to the sound transmission loss of the door system.
• Proactively control and minimize noise in rooms and buildings.
• Calculate and design effective acoustic rooms.
• Obtain certificates and test results to enhance competitiveness – sales, or bring products into large projects, promote, and sell to the market conveniently, transparently, and compliantly.

At the same time, DASM will conduct consulting and design work to create shape/structure/material solutions to fine-tune the sound insulation and noise reduction functions of the test sample in a streamlined, efficient, and cost-effective manner (in case standards are not yet met).

If previously you had some concerns, worries, and had to spend many fees for similar activities abroad, now you only need to contact DASM. The entire remaining process will be proactively executed by us as a full package in the fastest time to complete customer experience regarding us: DASM provides acoustic consulting services with truly superior quality, the most competitive prices in the industry along with thoughtful and dedicated customer care policies.
