Noise Meters
Here you will find a full range with an industrial standard noise meter / sound meter to suit every requirement. With the portable noise meter you can carry out measurements quickly to gain control of a situation or to set the sound meter to take timed measurements. The noise meter is important for all industries, especially by using it as a mobile noise meter which is able to assess office stress levels or street noise levels. Often problems arise from noisy neighbors or if bars and restaurants are in residential areas and produce noise levels after 10 pm in excess of what local laws permit. A noise meter / sound meter will help here.We can assess which noise meter or sound meter you require in relation to the issue you have and the relating laws (requirements regarding a sound meter and a sound meter’s usage vary depending on the country). We also have noise meter microphone extension cords, tripods, sound meter calibrators and calibration certificates for most noise meter models.

Measurement Condenser Microphone
ECM8000
The ECM8000 is a specialized condenser microphone designed for use with real-time analyzers, such as our ULTRACURVE DEQ2496, to provide an accurate acoustic picture of the room. You can then use your graphic EQ to fine-tune your system's performance to perfectly match the characteristics of any acoustic environment.

GSM RF Interference Test System
Guangzhou Jumho Electric Co., Ltd.
Cell phones and other wireless devices radiate powerful electromagnetic fields that can cause interference and noise in microphone signals. The interference and noise is called RF interference, which is an unwanted “signal” that occurs at the same time and frequency as a data signal. The RF interference disrupts the flow of data and degrades quality-of-service. Jumho Electric provides a cost-effective RF interference test system for GSM interference level measurement of wireless microphone.

Microphone Arrays
One of the most important parts of an Acoustic Camera is the microphone array. It determines the spatial distribution of the acoustic microphones and therefore measurement performance of the whole system. In order to achieve the maximum possible performance in any given application, we offer a wide variety of microphone arrays. No matter if the measurement is beamforming, intensity or holography ... we have the right microphone array. For special applications we can design and build custom made microphone arrays according to the requirements of the application.

C-Mic Auto Test System
BK9010B
Based on the BK3010V2 C-Mic Tester, the BK9010B is our fastest C-mic test system. Fully automatic, the BK9010B loads the mics in place and after testing, it sorts passing microphones into 8 quality classes, and failing microphones according to the reason they failed. Each mic is put into its appropriate bin. As testing progresses, you can view the data graphically in real time or save it to be viewed or analyzed later.

NI-9231, 8-Channel, 51.2 kS/s/channel, -5 V to 5 V, C Series Sound and Vibration Input Module
783610-01
8-Channel, 51.2 kS/s/channel, -5 V to 5 V, C Series Sound and Vibration Input Module - The NI-9231 is a high-density sound and vibration module that can measure signals from integrated electronic piezoelectric (IEPE) and non-IEPE sensors such as accelerometers, tachometers, and proximity probes. It can perform the high dynamic range measurements necessary for modern measurement microphones and accelerometers and features simultaneous sampling. The NI-9231 incorporates both a TEDS input path and 2 mA of IEPE signal excitation source that can be turned on and off, removing the need for external sensor power and reducing the complexity of the data acquisition system.

Surge Voltage Generator
SSG 1500
BAUR Prüf- und Messtechnik GmbH
Cable fault location with the BAUR SSG 1500. Surge voltage generators are used for pre-location and pinpointing of high- and low-resistive as well as intermittent faults in power cables. The energy stored in a high-voltage capacitor is released at regular intervals or as DC voltage. The thus generated acoustic signal at the fault position can be recorded with a ground microphone and a universal receiver.* High surge voltage up to 32 kV* Continuously adjustable voltage* Voltage monitoring through kV meters with 3 measuring ranges* Automatic discharge unit
