Audio devices

As the market demands the latest audio technology — for home theaters, streaming audio and smart speakers — users also demand higher sound quality.

Eastman offers durable and sustainable plastics that help preserve sound quality by improving audio performance. Our products reduce echo, improve noise cancellation and mitigate feedback while enduring whatever users put them through.

A sound choice

Eastman Tritan™ copolyester and Tritan™ Renew deliver a noticeably better listening experience by:

  • Reducing resonance of cabinets and enclosures that can degrade the listening experience
  • Improving active noise cancellation
  • Preventing feedback and feed-forward systems from going unstable by reducing housing resonance and interference

In short, consumers won’t want to put products made with Tritan down.

Reduce signal load

Our materials help simplify digital signal processing, which converts audio and video signals so they can be properly seen and/or heard on various devices. Our plastics:

  • Reduce computational load by removing resonance, leading to longer battery life 
  • Reduce printed circuit board computing power to mitigate cost 
  • Increase speaker/microphone system efficiency by reducing echo 
  • Allow higher speaker system sound pressure levels that incorporate microphones by reducing echo and reverberation

Enhance your design

Our plastics provide great aesthetics, durability and other advantages to enhance the user experience. 

Tritan and Tritan Renew

  • Proven in wearable, portable and stationary devices
  • Excellent impact strength and flex fatigue resistance
  • Excellent chemical resistance (including resistance to body oils, hygienic cleaners and cosmetics) 
  • Design flexibility, offering excellent secondary operations characteristics
  • Compliant with environmental regulations

How to compare plastics

We are a recognized leader in testing for vibration damping in appliances and other industries. We have applied this expertise to evaluate the impact of device housing materials on audio performance in four areas:

  1. Vibration damping and frequency response function
  2. Cumulative spectral decay in fully molded devices
  3. Total harmonic distortion in these devices
  4. Subjective responses from a panel of expert listeners

You can review the results of this testing in a white paper and webinar.
