Recorded December 13 – Presented by Eastman Chemical
Audio products have become integrated into our lives in ways that were unimaginable just a decade ago—in home theatres, audio streaming, and smart speakers, to name a few.
While technology advances and innovative applications continue to increase user convenience and enjoyment, material selection has often not kept pace.
Join this webinar to learn how vibration damping performance of polymers can impact audio devices, how to best evaluate this performance and to review data related to damping performance of common engineering polymers. Specific topics will include:
- Understand how vibration creates unwanted resonance in audio enclosures
- Review Center point Impedance test and evaluate inherent ability of common engineering polymers to dampen vibration and reduce distortion
- Present a case study a case study involving in-ear monitors (ear buds) that are fully molded from candidate polymers. The audio performance of each device is analyzed for both cumulative spectral decay (CSD) and total harmonic distortion (THD) to determine the role of the housing material on resonance, distortion, and listener experience.
Two Eastman polymers, Tritan™ copolyester and Eastman Trēva™ engineering bioplastic, are compared to common engineering polymers like PC and ABS. Tritan is well established in many consumer and medical electronic devices and Treva provides additional sustainability benefits. Both polymers have superior damping characteristics.
Learn which audio enclosure materials can help you keep pace with advancing technology and increasing demands for higher audio quality.
