Sound Measurement – ROGA Instruments

Here you will find sound measurement systems from professional measurement technology for all requirements in technical acoustics.

From our sound measurement set, which has been used in industry for over twenty years, to the class 1 USB microphone series and multi-microphone systems for sound power measurement, you will find everything from measurement to analysis here

Sound measurement with iSV1611

Measuring range 16 dB(A) – 140 dB
½” condenser microphone capsule pre-polarized
Frequency range: 4 Hz – 20 kHz ± 1.5 dB
1/2″ microphone capsule thread 60uns
Polar pattern: omnidirectional
Acoustic noise floor 16dBA
SPL max. 140dB
Sensitivity 40 mV/Pa

Measuring range right channel 51 – 140 dB(A)

Class 1 WS2F – IEC 61094-4

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.

Low-Noise Microphone Set

MMS214 + ZOOM UAC-232

Ultrasonic Microphone Set

RG-50 – MP48 – ZOOM UAC-232

Measurement Microphone Set

MI19 + Plug.n.DAQ Lite

I would like to take this opportunity to provide a brief introduction to the ARTA software, which includes Plug.n.DAQ Lite MMS 214 Low Noise Microphone and Microphone Calibrator.

In this demonstration, I will be showing the calibration of the measurement chain.

Since December 2024, the globally recognised FFT analyser and measurement microphone software ARTA has been released by the manufacturer as freeware.

We would like to thank the manufacturer for this generous support.

With calibrated microphone, ARTA can be used as a virtual IEC class 1 SPL meter with a real time modes:

Integrating SPL meter with 24 hours data logging,
Octave SPL meter with noise rating (NR, NC, PNC, RC,NCB),
Third octave SPL meter with report of loudness in sones and phones.
