3Environment
3.1 Ambient Temperature
The CAM iV64 is capable of operating in ambient temperatures between -10°C to 50°C (14°F to
122°F). Note that water can cause condensation, which can lead to damage in the device, the
ambient operating relative humidity is between 10-100% 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.
The CAM iV64 complies with the international protection standard IP54. Please be aware that the
Product is not watertight but splash-proof. The effectiveness against splashing under IP54 is possible,
only if the device is inspected periodically.
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 from
the 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 the
sound pressure. Sound Pressure Level (SPL) is a weighted sum of the frequency components
of 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 and
other 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 more
features 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 which
sound reaches the microphones in the array.
7. Frequency and Time Weightings
When measuring sound pressure level variations, it is important that the sound level meter
can give an accurate representation of what the human ear hears. Frequency weightings are
used 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 for
desired time-engagement. The time weightings that can be applied are Impulse, Fast and
Slow.
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 and
not visible on the display.

The microphone data obtained by the microphone array can be shown on the screen for a specific
frequency bandwidth. When the spectrum is visible in the display, the bandwidth can be selected by
touching the orange dot and drag this dot to the preferred frequency. Execute this for the lower and
higher frequency. You can also move the selected frequency band by touching it in the middle and
drag it to the preferred area of the spectrum.

Achtseweg Zuid 153H /Eindhoven /The Netherlands / T [phone] / E [e-mail] / W www.sorama.eu
4.6.4 SLM mode
Tap
to view the sound pressure level of the microphone data obtained by the
microphone array.
Tap
to add another weighting for the SPL measurement.
Frequency Weighting
Choose a weighting (Z, A, B or C), SLM target (‘Updating’ or ‘Measurement’) and choose the option
‘Full Spectrum’ or ‘Selected Frequency’.
SLM Target
Selecting ‘Updating’SLM target, will refresh the displayed dB value every second. Selecting
‘Measurement’SLM target, will start to collect dB levels when a measurement is started until the
measurement is stopped. After the measurement is stopped it will average these levels over the
measurement duration and show the corresponding value.

Page 20 of 41
Achtseweg Zuid 153H /Eindhoven /The Netherlands / T [phone] / E [e-mail] / W www.sorama.eu
‘Full spectrum’ will collect sound pressure level data for frequencies over the entire spectrum
available on the device. ‘Selected Frequency’ will only take the frequencies into account that are
currently selected (selectable in spectrum and spectrogram modules). By changing the selected
frequencies, the selection in this SLM entry will automatically change too.
Press ‘Add’ to add the new entry into the SLM module.
Adjusting SPL values
Tap
to adjust the settings in the screen.
Tap
to close the tab or
to remove the SPL mode.
