Advances in computing and communications technology have allowed for a shift in approach when it comes to measuring environmental noise. The speed of change has meant that there are no current standards that apply for a lot of systems that are used, or that a cumbersome and potentially expensive fudge…

Anyone who’s interested in measuring the performance of headsets, smart devices, telephones, earbuds and the like should be familiar with the need for a mouth simulator. This is a kind of ‘standardised’ loudspeaker, which emulates the frequency and dispersion characteristics of the human, and is also often found built-in to…

Construction developments, roads and other infrastructure projects often have a substantial and sometimes long-term impact on the local air quality. One of the most common impacts is increased dust or particulate matter (PM) concentrations. Depending on the perceived risk, monitoring may need to be carried out during both demolition and…

No, it’s not impossible at all, and probably it is related to measuring low levels. By having a think about how statistical levels are calculated, all should become clear. Firstly, the LAeq is the A-weighted equivalent energy over a certain period. It’s independent of time weighting (e.g. F), and the…

SvanNET is an on-line solution that supports multi-point connection with Svantek’s noise & vibration monitoring stations. To ensure the reliability and data security the SvanNET has been located on the Microsoft Azure™, the cloud platform working through global network of Microsoft-managed data centers.

Listen have recently announced the release of SoundCheck 19. This update includes powerful advancements for users making multichannel measurements. The single channel RTA is replaced with a new multi-channel version for viewing multiple signal paths simultaneously, a new RT60 room acoustics module is available, and WASAPI-exclusive mode and AmpConnect 621…

Here at AcSoft, we often get asked about the difference between FFT analysis and 1/3 octave analysis, so, equipped with an Apollo and Samurai software, John gives a short non-mathematical description of the two methods, and how they differ in practice, especially when converting from FFT to 1/3 octaves. To…

gfai tech has recently announced the release of a new feature for their software NoiseImage, DynaBeam. Because of this, scanning a 3D model with just your Acoustic Camera and representing the noise image results on it, is now possible. NoiseImage is a powerful software for acoustic measurements in fields such…

In 1928, Georg Neumann in Berlin made the world’s first condenser microphone, and his company became legendary in the world of studio microphones and music recording, and still today, the famous U87 microphone is a standard in that field. After Germany was split by the Iron Curtain after the war,…

New Class 2 instrument boasts patented MEMS microphone, lifetime warranty and measurement range up to 141dB Peak Svantek has launched its SV 973 sound level meter for reliable and accurate measurement of noise in the workplace. The new Class 2 instrument features a patented MEMs microphone with lifetime warranty and…

Since the country locked down in March, questions have arisen regarding calibration of instrumentation, either in the laboratory or in the field, and the implications of extended periods outside the recommended calibration intervals. When noise monitoring equipment is installed on site, it will be as the result of a planning…

To perform professional acoustic measurements, you need kit which meets a high standard of performance, after all, legal metrology has consequences. For example, if a noise limit is imposed on a construction site, you need to know with a demonstrable level of confidence, that your measurement is correct. In the…
