Highlighting this year’s show is the Schneeberger Miniscale system, a combined guiding and measuring system with an extremely small footprint. The MINISCALE, which is based on the already popular MINIRAIL, is suitable for many applications including microscope tables, biotechnology and semiconductor equipment. It has a resolution of 1 m and allows for measuring lengths of up to 1000 mm. Its optical measuring system is extremely small, thereby facilitating particularly compact and light designs.
Moore International also stock ground ball screws and trapezoidal lead screws in various lengths, in addition to bronze, steel and cast iron nuts and a variety of anti-backlash nuts. The company now also offers full CNC machining produced to customer drawings, which can range from large quantity batch work to small orders for next-day delivery.

time, in his own words, he is looking for a “win- win-win” scenario
W on noise measurement and
compliance. For many years Chris has been brought in by
Festival organisers for his expertise in noise measurement and acoustic understanding at large outdoor events. From the planning stages through to the round the clock cover on the day, Chris has to ensure he has the right equipment and data to assess the risks and quality of noise from the minute the first festival goer comes through the gate. “I really want to achieve a win-win-win situation at every event where we can get more volume onsite, less volume off site but still stay within the limits of noise legislation. Getting that balance right means everyone’s happy but it isn’t easy,” he said. “You have to be able to analyse data in a live situation and respond immediately,
relaying
instructions via mobile phones or two-way radios. “I would be on site 24/7 during an event, taking constant noise measurements. The data is used to either confirm or adjust the acoustics on site and this could be in various places.” To help Chris achieve this, he works with Cirrus Research and uses its Optimus Green Sound Level Meter - most recently at the urban Electric Eden Festival in the North West and, in contrast, at the more rural Ravenstonedale Festival.
One of the most important features of the Optimus for Chris was the visual and graphic displays that could be seen at night when he was taking measurements on site and during live events.

“There are quite a few things that make it the best device for me but, simply put, it’s the easiest device to use and get the information I need quickly. I can use the Optimus to see all types of sound data on the screen with only a quick curser move.
“Even when I’m taking a live LAeq recording, it’s possible to quickly switch back and forth between screen views (DBA / 1:1 or 1:3 octave graphic/data views for example). This enables me to make quick and multiple decisions, act immediately to advice a sound engineer in a live situation and record the data too. The fact that I can do this on a pitch black country lane in the middle of a night is also very useful!” Another big advantage for Chris is that the Optimus simultaneously records everything, whatever measurement is being taken, and he also uses the Noise Tools supporting software to analyse and report on any type of measurement later on. Voice Tag and live audio recording that instantly switch on and off is also a must-have as far as Chris is concerned. “The data can be used as evidence that the event met all necessary legislations and noise limits when it comes to local residents and noise nuisance issues. It also allows us to monitor live event acoustics and adjust settings for the listening audience, he added.
“It can be seen and stored real time for later analysis but it also allows me to advise throughout an event that the sound levels are correct or if they need adjusting due to changes in the weather, for example. I use all this evidence to then write a full report after the event to show we met all the legal requirements.

“The Optimus measures both the Dba and the frequencies of noise levels so we can see what is permissible. This ensures that noise levels don’t go over certain limits at certain times, something that is important for nearby residents.”

Chris is already looking ahead and plans to use the Optimus Green for future events. “It’s an important part of forward planning to look where we can use techniques and the site infrastructure to try and set up acoustic barriers and alleviate problems in advance. Having the right data is all part of the process.” he concludes.
