GUITAR SOUNDBOARD MEASUREMENTS FOR REPEATABLE ACOUSTIC PERFORMANCE MANUFACTURING

The following post gives a brief summary of a research paper submitted to Reproduced Sound 2018 primarily written by Ludovico Ausiello, with contributions from Lawrence Yule, Giacomo Squicciarini, and Chris Barlow.

A system for performing fast, accurate and objective assessment of the time-frequency response of guitar soundboards has been developed, using an application of the sine-sweep method commonly used to retrieve impulse responses of acoustic spaces or electro-acoustic devices.

Spatial Audio At Solent

Welcome to RM707, our newly configured spatial audio lab! The loudspeaker installation here allows us to pan sounds around in full surround sound, using a system known as ambisonics. One of the major drawbacks to traditional surround sound formats (5.1, 7.1 etc.) is that they’re channel based, meaning that the loudspeakers have to orientated in a particular way (to ITU spec), and when mixing audio around there are a very limited number of positions to work with. Ambisonics allows us to decode audio to any loudspeaker configuration, including loudspeakers positioned at different heights, as well as being able to pan sounds to positions in space rather than just to particular channels.

Up Your Output! 2017

Southampton Solent University was pleased to host the Audio Engineering Society’s Up Your Output! event this past weekend (18th & 19th of March), co-organised by ISVR, University of Southampton. This annual event, which has run since 2011, offered students and recent graduates the opportunity to learn, network, and develop both friendships and career opportunities.

The Acoustics of Sonic Booms

Sonic booms are something that most people will have heard at some point in their lives, perhaps from planes passing by at an airshow, or from a bull whip (yes, the tip travels faster than the speed of sound!), but what exactly are they? and how do they produce such an incredible noise? This posts explores the acoustics of sonic booms.

A Guide To Hearing Protection

In many cases the use of hearing protection is essential for protecting yourself from loud and potentially dangerous noise, but there are many different types of hearing protection available for many different scenarios. Knowing which type of protection is the most appropriate for you is important, the guide below should help you to make a more informed decision about which to be using and when.

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
