Webinar Recording: MetaWrx Isolator Introduction

Join Tonya Levine, Kinetics Director of Sales for the Noise Control Building Materials (NCBM) Market, and Chris Williams, NCBM Territory Development Manager, to learn more about the new MetaWrx isolator! MetaWrx is a new class of isolator technology that exploits an integrative structural-material design based on foundational principles of structural dynamics to maximize damping when shock and vibration loads are transversely applied across the elaborate network of beams on the topside and underside of the isolator.

This is very interesting. Could you please explain why you decided to show the IIC and HIIC results but not those for low frequency impacts? Wouldn't the dropping of weights be better represented by the LIIC rating?

Hi Henning. That will be the focus of our next round of testing. We did execute 100lb weight drops from a specified height in the lab of an unisolated versus isolated floor system and measured the difference in sound pressure levels, about a 6dB difference at 63Hz and from about 125Hz to 8KHz ranges from about 14-18dB SPL. We conducted addditional testing with a variety of weights and can share that with you. While we're on the topic, yes, there is the LIIC. What is your opinion of capturing 20Hz - 80Hz with a tapping machine versus a standardized medicine ball weight drop test. We're inclined to head the route of the medicine ball, as the physics of a small tapping machine hammer to generate the lows we aim to accurately capture seem, versus ball drops to simulate the low thudding of footsteps, we're debating but intend to pull the trigger on low frequency testing sooner than later. Interested in your thoughts. Shoot me an email and we can dialogue.
