43AH consists of the ITU-T Rec. P57 Type 2 Ear Simulator and Type 3.2 Simplified Low-leak Pinna Simulator and is designed for making ITU-T standardized tests of telephone handsets, receivers and receiver/loudspeaker modules on the production line.
Besides the ear and pinna simulators, G.R.A.S. 43AH includes a detachable front-plate that can be machined to make well-defined testing on various receiver related items. A calibration adapter to be used with G.R.A.S. 42AA Pistonphone/G.R.A.S. 42AP Pistonphone is included.
43AH can also be delivered with customized front plates that will enable leakage-controlled testing according to your specific needs.
