Coffee shops provide great acoustics for creativity

As acousticians, we know (or like to think!) that the sound around us affects us in ways that most people don’t realise. Whether it’s reverb in your classroom that means you can’t hear the teacher properly, or in the shower making you think you’re a great singer, the acoustic spaces around us have a pretty  profound effect on the way we experience life, that often goes unnoticed.

This makes you wonder what the ideal acoustic specification for a space is. What’s the best reverb time for music, or the best noise level for concentrating, or perhaps being creative? This is the question that Ravi Mehta, Rui Zhu and Amar Cheema undertook to answer in their 2012 paper; “Is Noise Always Bad? Exploring the Effects of Ambient Noise on Creative Cognition”.1

Tutorial: Measuring Reverberation Time – Part 2 – Deconvolution

In our previous reverberation time measurement tutorial an impulse response, created by bursting a balloon, was used as the measurement signal. This is a quick and simple method of carrying out a reverberation time measurement, but may not be the most accurate method. In this tutorial we will look at an alternative method that can provide improved results.

How Loud Is Too Loud?

The World Health Organisation states that loud noise is the single biggest preventable cause of hearing loss in the UK. Due to advances in portable media player technology, users are now able to store and play music for much longer. Due to this, there is a huge potential risk for overexposure to noise using these devices. It is now estimated that over 4 million young people in the UK are suffering with the effects of noise induced hearing loss from listening to amplified music in the UK.
