Over recent years we have seen big increases in all types of building projects from domestic houses to major infrastructure projects like HS2. More and more local authorities are including monitoring requirements for noise, dust and vibration right from the planning stage and the onus is very much on construction…

By Aidan Hubbard, Sales Director The most important part of my job is to make sure people understand IEC 61672 and to make sure that people fully understand the benefits of having instrumentation with this standard applied. Some instrumentation suppliers will claim to comply to IEC 61672 but they don’t…

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…

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,…
