AUDIO: ADJUSTING THE VOLUME

Gain

Volume gain affects the way the detector amplifies target audio

responses in respect to the strength of the original signal.

Looking at figure 5.16, it is clear that with a setting of 1 the sound

produced will be proportional to the strength of the signal for the

whole range of signals. Based on this and the depth indication,

some information on the size of the target can be inferred. It

should be noted that in this case weak signals will produce an

accordingly faint audio signal.

With the preset value of 5, the audio response is being partially

amplified. Weak to medium strength signals will give proportional

responses, but strong signals will not sound much louder than

medium ones because the sound has reached its maximum limit

(Figure 5.17).

On the other hand, with a setting of 10, all but the weakest signals

will be amplified to a very strong audio response (Figure 5.16). No

indication of size or strength of target signal can be deduced in

this case, but even weak target signals will be easier to hear.
