RTE is the worldwide leader in acoustic testing technology for serial production. Since its foundation, the company has been developing, manufacturing and supplying products and testing equipment based on acoustic evaluation methods. Its product range focuses on testing systems and facilities for noise and functional testing, in particular acoustic material testing and acoustic process monitoring.

Services include carrying out feasibility studies (product sampling) for acoustic product testing as well as courses and training for users.

RTE is collaborating with R&D companies and partners to continuously develop acoustic testing technology for specific applications and different fields of application. Each year we re-invest a portion of our turnover research and development projects.

In addition to its own sales division at the company site in Pfinztal, near Karlsruhe, RTE successfully collaborates with distribution partners in other European countries and overseas.

Since September 2017, RTE has been operating in India under its joint venture RTE Transweigh India Private ltd.
