Introduction The auditory world around us is filled with various types of noise, and while some are simply distracting or annoying, others serve practical purposes. You're probably familiar with the…
The following post on Joseph Fourier is our second in the On The Shoulders of Giants series. It is hard to overstate Joseph Fourier's importance in the field of sound…
We have scoured LinkedIn, Twitter and the rest of the Internet to find these cool acoustics links. And since two of them are themselves lists of 10 you're actually getting…
To welcome you to 2015 here's our latest collection of news articles, videos and other miscellaneous links on noise, sound, acoustics and vibration that have caught our eye over the…

There's a distinct coffee "flavour" to our latest digest with two stories related to the bean. We hope you enjoy the articles we've found and as always please leave your…
I hope you like our latest collection of news, articles and videos from the world of acoustics, vibration and analysis. This issue of the digest is very "acoustical" and includes…
By power spectrum we are talking about an ASD (Auto Spectral Density) or PSD (Power Spectral Density). In fact PSD is often used when really ASD would be more correct.
Taking any signal and performing a frequency analysis using an ASD or a PSD will give the energy over a range of frequencies. (more…)
Our latest selection of news and interesting stories from around the web. There's definitely a motor sports theme to this edition of the digest, but with a bit of space…
Here is our latest collection of sound, vibration, condition monitoring & acoustics articles from around the web. In this issue we take you on a sonic journey from Stonehenge to…
Are you a Flipboard user? "What is Flipboard?" some of you will ask. Flipboard is an up-and-coming mobile app for pulling all of your news sources and social media together…

Our previous collection of cool engineering videos in 2010 proved so popular that we just had to make another list. So here we present another 10 really cool engineering videos.…
Are you interested in measuring torsional vibration? Need to measure shaft twist? Worried about rotational jitter? Don't worry, we've got it covered. Here we have gathered together our most popular…
We've come across a number of great noise related resources lately. So, rather than keep them all to ourselves, we have decided to share them with our readers. Thanks should…
The term synchronous data is usually applied to vibration or acoustic data that is captured from an item of rotating equipment at regularly spaced angle intervals as distinct from regularly spaced time intervals. The rotating part could be an engine, a gear wheel, a drive shaft, a turbine rotor, a propeller, a turbocharger or any other type of rotary mechanical device. Typically these items are subjected to out-of-balance forces that cause them to vibrate at frequencies that are multiples of the fundamental (once per revolution) rotation speed frequency. (more…)
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…)
