Show curser on graph provides information about each
specific measured point in the curve. The curser is "locked" to
the curve and a frequency and intensity label will be displayed
at the curser's position, as illustrated below:
Stimulus Selection allows for selecting a test stimulus. The
dropdown is only present for custom made test protocols. The
standards (e.g. ANSI and IEC) have fixed stimuli.
Monitor: If you wish to listen to the amplified stimulus through a
monitor.
1. Connect a monitor speaker the monitor output on the
hardware.
2. Tick the Monitor check box.
3. Use the slider to turn the sound level up and down.
Note that the sound from the monitor may be very soft (compared
to the audiometry monitoring). It is louder for audiometry because
the audiometric equipment is producing the signal that is
monitored. In HIT440 the hearing instrument produces the
monitored signal meaning that it cannot be controlled by the
equipment. However, if you have an active speaker it will be
louder.
External sound: You can present an external sound through for
example a CD player if you have a piece of music/speech you
wish to use. This may have a strong effect for counselling
purposes.
1. Connect the CD player to the CD1 input on the hardware.
2. Press START in the software and then tick the External
sound check box. The external sound will then play
together with the signal.
3. Use the slider to turn the sound level up and down.
