For many years, testing audio equipment with acoustic measurements was part of approval measurements for cell phones. Over the past few years, the field of application for these tests has expanded. Audio tests are now also required as part of the approval of voice or emergency call assistance systems.
We are accredited for testing audio equipment devices and their respective voice quality. Within the scope of our services, we specialize, among other things, in testing the acoustic quality assessment of mobile devices. Depending on the requirements, the acoustic tests are performed with test headphones or the so-called “HATS” (head and torso simulators) as well as professional microphones and audio sources. In addition, we test the operationality and quality of the speech functions of head units and emergency call assistance systems in vehicles for the automotive industry – with the help of specially designed measurement equipment.
cetecom advanced specializes in particular in performing electroacoustic tests on hearing aids. The recently completely modernized laboratories have fully and partially sound-absorbing chambers, audiological measurement rooms and an audiological measurement stand, each equipped with professional measurement analyzers, microphones and audio sources. The portfolio of acoustic measurements of cetecom advanced advanced includes the services mentioned below.
For some years now, the use of emergency call assistance systems in vehicles of various classes has been mandatory in many countries and regions of the world (including eCall, ERA-GLONASS).
We test the operationality and quality of the voice functions of head units and emergency call assistance systems in vehicles for the automotive industry. These tests are usually the basis for the market approval of the emergency call systems.
