What Does a Decibel ‘Sound’ Like?

The term decibel or ‘dB’ is often used in the development and construction industries but very few people know what, for example, a 1dB noise reduction sounds like, or whether it is worth achieving. This can lead to unnecessary argument over what can be negligible improvements.

This short film shows the effect of different reductions in noise levels (in this case 1dB, 3dB, 5dB and 10dB) comparing the starting ‘reference’ noise level with a given noise reduction. It replays the same short film clip over and over so a direct comparison between the different levels is possible.

Food for thought perhaps when someone insists that you achieve that last 1dB of a contractual requirement!
