Testing Times : Why & How We Measure Noise & Vibration

We’re going to look today at some of the practical aspects of how we measure noise & vibration and consider why it’s important that you should measure and, more importantly, understand the noise and vibration of your products

The current global economic situation means that times are tough for everyone. It’s now that you need a competitive edge; that little bit extra. You need that advantage that will convince your customers to choose your product over your competitors.

Plainly, there are many factors that influence a buyer. The visual design of an object is obviously very important, but what about the sound? Automobiles are a good example of products that need to sound right. Sure, a potential customer may really love that piece of shiny chrome trim, but perhaps they’ll be more influenced by the sound of the V8 or, maybe, the smooth silent ride.

While we concentrate mainly on automotive examples in this article, it’s the same around the house. Will a buyer really want a dishwasher that makes so much noise they can’t listen to the radio or a fridge that makes them jump every time it switches on and off? It’s all very well having the blackest, shiniest bevel on your 42″ TV, but what if the discerning customer thinks the sound isn’t good enough?

So, without further ado, let’s look at some of the many and varied examples of how we go about testing noise, vibration, harshness & refinement.


So there you have it! A quick tour of just a few of the whys and wherefores of measuring noise & vibration. As we said at the start, the theme of this post is automotive testing, but the same techniques of measurement and analysis are just as valid across a whole range of products from aircraft to mobile phones.
