Material Performance Evaluation

Through the use of its ISO / IEC 17025 accredited Laboratory, K&SE can determine the acoustical properties of various materials suitable for noise control applications. Once the acoustic behavior of the material is known, K&SE can help to optimize the material’s performance for a particular application or requirement. Based on the need materials are tested according to standardized test methods, OEM specifications, or customized methods. Such studies can involve the measurement of:

• Sound Transmission Loss
• Sound Absorption Coefficients
• Vibration Damping Performance
• Vibration Isolation Performance

To help insure quality testing we follow standardized test methods such as:

• ASTM C423 – Random Incidence Sound Absorption (Full-size Reverberation Room)
• SAE Standard (Pending)- Small Sample Random Incidence Sound Absorption
• ASTM E1050 – Normal Incidence Sound Absorption
• SAE J1400 – Small Sample Sound Transmission Loss
• SAE J1637 – Vibration Damping
• ASTM E756 - Vibration Damping
• ISO 3471/ANSI S12.51 – Sound Power Level
• ASTM E2249 – Sound Intensity Based Transmission Loss
• ASTM C522 – Airflow Resistance of Acoustical Materials
