Nowhere to hide / Hacked off
When computer programmer, and former subcontractor for the NSA, Edward Snowden’s identity was revealed at his request, he said, “I do not want to live in a world where everything I do or say is recorded.” And regardless of our views on Snowden, not many of us would disagree with his statement, but the harsh and frightening reality is that there is a hacker attack every 39 seconds and 300,000 new malware created every single day.
LAN-XI Open API: An Open Ecosystem
The Open API protocol makes it possible to use LAN-XI hardware in conjunction with third-party programs and applications to customize control and access real time data on LAN-XI modules. Rely on our reliable and proven systems and get the most out of LAN-XI Open API.
Cutting-edge Blade Maintenance
Since September 2011, an exciting EUDP project has been underway to develop a practical way to detect, localize and predict damage to wind turbine blades. The associated cost of maintaining and repairing blades is a very real issue for wind farm operators and so far no remote inspection method has offered a viable solution. Thanks to the project, the best answer could lie in sophisticated algorithms using vibration measurements with considerable potential above and beyond the wind industry.
Listening to the Community
At BHP Billiton, the way results are achieved is just as important as the results themselves, and the impact of mining on surrounding communities is a concern that is taken very seriously. In Western Australia, measures to reduce noise for neighbours to a bauxite mine involved close consultation with the public, monitoring noise at residential locations and creating community forums.
The Fauna Philharmonics
They howl, thump, bang, chirp and rumble. The sound and vibration repertoire of these animals would indeed make an interesting symphony. Key to their survival, these weird and wonderful creatures use sound and vibration to navigate, hunt, communicate, attract mates and ward off predators.
Savings in The Pipeline
According to the EU, one of our most promising untapped sources of renewable energy is the energy we can save by mitigating leakage and waste. Arne Jensen is at the forefront of harnessing wasted energy with his acoustic technology that detects and stops leakage in district heating systems – before it even begins.
Can You Play The Asphaltophone?
When you drive over lumps and bumps on the road, the sounds rumble up into your car. But you might be surprised to learn just how much road makers can control theses sounds.
The Loudest Sound, Naturally
The loudest sound in recorded history came from the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27, 1883. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.
今年是Brüel & Kjær公司成立75周年。在过去的75年中，Brüel & Kjær一直由富有远见的工程师和发明家负责创新并创造了许多世界第一。我们有着悠久而辉煌的历史，回首往昔，我们愿与大家分享一些亮点。
Multiple Vehicle Pass-by Tests
Engineers can assess noise from many vehicles at the same time with data acquisition synchronized by GPS.
Leap through jet engine testing
As aircraft engine makers like Snecma address emissions and cost challenges, scalable, high-performance test and analysis systems lie behind their rapid response.
Wind Tunnel Vision
High in the French Alps on what could be a James Bond film set, ONERA’s large wind tunnel helps to perfect future aircraft. As they master the challenges of extracting precise acoustic data, ONERA Modane will soon offer a one-stop shop for both aerodynamics and aircraft noise.
