Tips on Operating Product
Sound Source Capturing
1) Observe whether there are prominent spectral signals or frequency spikes
in the spectrum graph. If there are, move the frequency selection box to
include the frequency range where the prominent spectral signals or
frequency spikes are located, and then see if a sound source appears in
the image.
2) Adjusting the dynamic range to a relatively large value can simultaneously
capture multiple sound sources with similar SPL in the image. When the
SPL of sound sources in the image is very different, relatively small dynamic
range may cause the large sound source to drown the small one.
Elimination of Reflection Interference
When users are not sure whether the sound source in the image is the actual
sound source or the reflected virtual image of the sound source, they can try to
capture it from different angles. If it can be captured from different angles, it is
generally the actual sound source. Because the reflected virtual image of the
sound source may have position offset or may even disappear at different
angles.
Elimination of Interference Noise
1) It is easily disturbed by ambient noise in low frequency band. According to
the actual situation of the sound source, it is recommended to use the
middle or high frequency band to locate the sound source.
2) Selecting a relatively narrow frequency band to locate the sound source
can eliminate the interference noise of other frequency bands.
Maintenance
1) Keep the acoustic sensor hole clean. When the acoustic sensor hole has
dust, please blow gently to clean, and do not use a wet cloth.
2) If the product is not used for a long time, put it in the protective case after
charging and store it in a dry environment at room temperature.
