3 Environment
3.1 Ambient Temperature
The CAM iV64 is capable of operating in ambient temperatures between 2°C to 50°C (35.6 °F to
122°F). Note that water can cause condensation, which can lead to damage in the device, theambient operating relative humidity is between 10-90% RH (non-condensing).

3.2 Protection
Warning
The AOP (Acoustic Overload Point) of the microphones is 132 dB and a user could potentially damage
the microphones if the microphones are subjected to sound sources higher than the AOP.
Warning
The USB-C connector port is not used for charging, and it is solely used for data communication.
Any water entering the MEMS microphones may cause the device to show incorrect measurement
output values. Water entering the holes of the microphones should always be avoided. In case water
was in contact with the microphones, place the sensor head such that any water can drip out fromthe microphone holes and let it dry in this position.

4.3 Terms to know
1. Sound Pressure Level
The sound is defined as pressure variations in the air which is generally quantified by thesound pressure. Sound Pressure Level (SPL) is a weighted sum of the frequency componentsof acoustic signals. SPL is expressed in decibels (dB SPL).
2. SLM (Sound Level Meter)
Sound Level Meter indicates the Sound Pressure Level (SPL) as measured by the Product.
3. Frequency Spectrum
Frequency Spectrum is the distribution of the amplitudes (dB SPL) of each frequency
component against frequency (Hz). In other words: Your signal recording consists of different
frequency components which all contribute to the sound.
4. Spectrogram
Spectrogram can show a sudden onset of a sound. Often it can be easier to see clicks andother glitches in this view rather than in a time or spectrum analysis.
5. Field of view (FOV)
Horizontal/Vertical observation angels of the webcam. The FOV depends on how many
features are opened (Spectrum, Spectrogram and dB SPL meter). When opening morefeatures on the Sorama CAM iV64 screen, the horizontal FOV will increase and the vertical
FOV will reduce slightly.
No features open: Horizontal FOV 23.8° and Vertical FOV 41°
All features open: Horizontal FOV 53° and Vertical FOV 38.2°.
6. Beamforming
A signal processing technique used to identify the location of sound by using an array of
microphones. The localization of sound is determined by the difference in time at whichsound reaches the microphones in the array.
7. Frequency and Time Weightings
When measuring sound pressure level variations, it is important that the sound level metercan give an accurate representation of what the human ear hears. Frequency weightings areused to correlate the SPL at each frequency component for different applications. Frequency
weightings that can be applied are Z, A, B and C.
The streaming SPL varies rapidly in time on display, time weightings act like a buffer fordesired time-engagement. The time weightings that can be applied are Impulse, Fast andSlow.
8. Frequency Band Selection
Frequency band selection acts like a window, focusing on the selected frequency range in the
spectrum, the frequency ranges of the sound, other than the selection are filtered out andnot visible on the display.
