Connecting the headphones
It is recommended to connect the supplied headphones to the
SL800R at all times. Human hearing already perceives very subtle
signal changes with regard to its volume and intensity, so in
addition to the LED indication you are provided with a valuable
acoustic component for a yet more precise detection of ultrasound
sources.
Warning
Risk of hearing damage due to unknown, intense
ultrasound sources.
The sound spectrum perceptible by human ears lies in
the frequency range between 16 Hz and 20,000 Hz.
Hence, ultrasound is clearly outside of this range. As a
result potential, more or less intense ultrasound sources
in the immediate measuring environment go unnoticed
without technical aids. Nonetheless, they can
inadvertently lead to hearing damage if the auditory
system is suddenly faced with the high-intensity
ultrasound rendered audible by use of these aids.
For that reason always set the volume control at the
headphones to minimum before starting a measurement
(narrow end of the wedge at the volume control).
Increase the volume only slowly.
If necessary, reduce the volume when approaching a
potential ultrasound source.
