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 in 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.
The single-handed controls on the PA5 give full control over frequency and intensity and make the test process quick, flexible and comfortable.
The PA5 audiometer is powered by three standard AA batteries. To save battery life it will turn off automatically after a period of inactivity and reactivate when a stimulation switch is touched again.
