40 Years of RTE – From Noise and Vibration Testing to Connected Testing Technology

RTE began its journey in 1986 with a clearly defined objective: to replace subjective listening evaluations with objective, industrial-grade testing technology. At a time when quality was often still assessed manually “by ear,” RTE was an early adopter of digital signal processing, in-house hardware and software development, and the consistent use of computer-based measurement methods. 

This led to a technological evolution that systematically transferred acoustic testing technology into industrial applications:
from the first networked test benches and standardized test systems to integrated solutions for cross-site quality monitoring. The goal then—and now—is to capture and analyze acoustic signals in a reproducible way and to derive clear, unambiguous quality decisions from them. 

Today—40 years later—this has resulted in an end-to-end testing architecture for automation: connected, scalable, and data-driven. It enables consistent, objective, and reproducible quality assessments in demanding production environments.
