5 Unusual & Interesting Acoustic Webpages
Many of our readers spend their days studying or solving noise problems. In our day-to-day work it’s often easy to forget some of the more unusual applications and miss out on the more interesting side of acoustics. So we have gathered together 5 examples of unusual or interesting acoustic work. If you know of any other out of the ordinary acoustic applications or websites then please leave a comment in the box at the end of this post. (more…)

10 Great Renewable Energy Videos
Here we have gathered together a collection of interesting, informative and some slightly offbeat examples of renewable energy. We’ve tried to find a good selection of both power generation and transportation technologies. With all of the resources available for renewable projects at the present time, this has to be one of the most exciting areas of engineering at the moment.
Take a look at the videos and let us know your views and experiences in the comments section at the bottom of the page.
Do You Need To Measure Brake Noise?
The objective of the brake noise tests was to record the braking events of cars being driven on various types of road and classify those events according to their type (Groan, Creep or Squeal etc) and severity. To do this the customer needed a system capable of working for long periods inside a vehicle in fairly tough conditions (high ambient temperatures, rough road) that was both quick to install and to remove.
On previous tests a system from another supplier had turned out to be unreliable and had failed to cope with the harsh environment. The analysis processing had also proved tedious and time consuming due to the huge amount of data created when testing several vehicles over many days.
5 Famous Moments of Genius

6 Brilliant Richard Feynman Videos
I had absolutely no idea that this archive existed on the BBC website and so it was a joy to discover that it did. I have never come across anyone else who has been able to explain scientific principles in a way that makes them so easy to understand as Richard Feynman could. It is rare to find a mind so capable of grasping the most complex aspects of science and yet is also able to reduce them to a form that we mere mortals can understand.
Buzzing & Flickring: Two New Ways To Keep In Touch
Prosig have recently added two new ways for our readers to keep in touch with new articles on the blog, happenings at Prosig and other interesting information that we find about NVH, noise & vibration measurement and condition monitoring. Now, as well as Twitter, Facebook & LinkedIn, we can be found on Google Buzz and Flickr.

Developing an Algorithm for Tick Detection
An investigation was made of a sample of automotive components where some were exhibiting a high frequency “tick” or rattle during each operating cycle. This feature could be heard above the normal operating noise. The problem this posed was to measure and analyze components in an objective fashion and classify components as “good” or “bad”.
