The PA5 is a free field audiometer designed for trained healthcare professionals involved in test-ing young children. It features one hand operation, silent buttons and a variety of light and sound stimuli.
Conditioned Orientation Response
Typically, two PA5s are used for the COR test, one in each hand. This allows the tester to use either unit to evoke head turn and provide visual reinforcement. The single-hand controls on the PA5 give full control over frequency and intensity and make the test process quick, flexible and comfortable.
Extended battery life
The PA5 is powered by three standard AA batteries. It will turn off automatically after a period of inactivity and reactivate when a stimulation switch is touched.
Silent presentation buttons
The two stimuli, light and sound, are controlled silent buttons. Both stimuli can be presented simultaneously by letting one finger touch both buttons. This gives full freedom operating COR, VRA and APR tests.
The PA5 includes white noise as well as warble and narrow band stimuli. White Noise has been shown to be especially useful for evoking responses in the early months.
With children old enough to cooperate, it is possible to connect a single TDH39 headphone to the PA5 and obtain audiometric thresholds. With a headphone attached, the PA5 automatically adjusts to the correct calibration for the TDH39.
