Abstract

According to some embodiments, a method includes placing a device under test (DUT) in a test chamber and applying a pulse-modulated RF wireless test signal to the DUT in the test chamber. The method further includes detecting an acoustic output of the DUT. In addition or as an alternative to applying the pulse-modulated test signal, the test signal strength may be at a level of 30 V/m or 90 V/m. If the DUT is a telephone, it may be coupled via a voice signal path to another telephone, and an output of the other telephone may also be detected.
