Environmental Noise Monitors
Noise is one of the most complained about aspects of the environment, as not only does it have the potential to affect quality of life, it can also be difficult to monitor and therefore control. This type of noise is generally called environmental noise. There are many man-made sources of environmental noise, such as wind turbines, industrial sites, roads and traffic etc. If you are looking for equipment to measure noise in the workplace, look at sound level meters.

Noise Dose Meters
Here you will find a full range with an industrial standard noise dose meter to suit every requirement. With the portable noise dose meter you can carry out measurements quickly to gain control of a situation or to set the device to take timed measurements. The noise dose meter is important for all industries, especially by using it as a mobile device 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 10pm in excess of what local laws permit. We, of course, can assess which noise dose meter you require in relation to the issue you have and the relating laws. We also have microphone extension cords, tripods, calibrators and calibration certificates for most models of noise dose meter.

SNR Noise Generator
CNG-EbNo
The CNG-EbNo is a fully automated precision signal to noise (AWGN) generator that sets, and maintains a highly accurate ratio between a user supplied carrier and internally generated noise, over a wide range of signal power levels and frequencies. The internal AWGN meter provides repeatable SNR waveforms for accurate signal generation. The instrument gives system, design, and test engineers in the telecommunications industry a single tool to generate precision signal to noise ratios. These signals are used to compare theoretical BER to SNR ratios, found in "waterfall" type graphs, with measured values from the DUT to evaluate different modulation schemes. Users can obtain higher yield through automated testing, plus increased confidence from repeatable, accurate test results. Standard units can be modified for specific customer requirements. Please consult the factory for pricing and availability of these requests.
