Pickleball paddle noise characterization with CoCo-80X and Post Analyzer, Dec 2023

Pickleball noise is comprised of several interactions, one being the paddle impacting the ball and another being people cheering and shouting. The paddle impact noise is one of the issues the industry has faced, and some paddle manufacturers are claiming quiet noise characteristics of their paddles.

In this opportunity, we used the Crystal Instrument’s CoCo-80X to characterize the noise from several paddles for acoustic comparison. The equipment consisted of three (3) microphones mounted on an arch boom and seven specimens to be tested (including different paddles). The testing was done inside the MD Acoustics, LLC’s anechoic chamber at the facilities in Gilbert, AZ.

Dynamic Signal Analysis Basics

DSA is often referred to Dynamic Signal Analysis or Dynamic Signal Analyzer depending on the context. DSA uses various technologies for digital signal processing. Among them, the most fundamental and popular technology is based on the so-called Fast Fourier Transform (FFT). The FFT transforms the time domain signals into the frequency domain. To perform FFT-based measurements, it is important to understand the fundamental issues and computations involved.

Electric Vehicle Battery Show (Novi, MI, September 12-14, 2023)

The Electric Vehicle Battery Show brings together the top talent in the EV Battery industry, from design to manufacturing and testing. This year, the show saw hundreds of exhibitors and thousands of attendees come together to share the latest insights and developments in this exciting industry.

NASA/JPL High-Tech Conference 2023 and ADAS 2023

Crystal Instruments attended the High-Tech Conference co-hosted by NASA/JPL and the City of Pasadena. The High-Tech Conference is an excellent platform for small businesses to gather insights on potential opportunities through exhibitions, workshops, and networking sessions.

CoCo-80X and EDM Post Analyzer usage for measurement and analysis of acoustic properties

Acoustic Consultants are often tasked with analyzing the noise absorption in rooms, studio garages, and storage spaces. The primary challenge in this type of analysis is to find a dynamic signal analyzer with portability, high sampling rate functionality, and complex analysis.

I'm still overwhelmed by all this modal stuff Laplace, Fourier, FRFs, and all that! Can you put the big picture together for me?

Sure…sometimes it helps to stand back and look at everything from a complete picture. I have a figure that I have used for many years now to help people see things more clearly. I call it "The Big Picture". Let's just look at this picture and discuss all the pieces individually.
