Sound measurement with iSV1611
This presentation shows the flexibility of our iSV1611 USB measurement microphone. By selecting different microphone capsules we can use it for infrasound or ultrasound applications.
The standard frequency bandwidth is 4 Hz to 20 kHz.
With the MK 222 E infrasound microphone capsule, measurements from 1 Hz are possible.
With the 1/2″ to 1/4″ adapter and the MK 301 E capsule, measurements from 5 Hz to 80 kHz are possible.
Using the MK 342 E capsule with a sensitivity of 0.25 mV/Pa, the iSV1611-HSPL-342 can measure high sound pressure levels up to 184 dB.
USB measurement microphone model iSV1611 is a digital microphone with USB interface, consisting of pre-polarized ½” condenser microphone capsule, preamplifier, 2 channel (Stereo) ADC and USB interface, which can be used with apps on smartphone, tablet or PC.
PC, smartphone, or tablet receive the digitized 2 channel signal data via USB cable connected to iSV1611.
Dual channel operation allows simultaneous measuring.

We would like to point out that accelerometers with charge output can also be connected to the iSV1611 preamplifier if a 1/2” to 10-32 thread adapter is used.
In this way, vibration measurements can be realized with the same measurement technology.
Our optional NVH-FFT software is available for carrying out sensor-specific analyses in dB or acceleration in g.
