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.

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.

Disclaimer: This guide is written for Windows users however all tools are also available for Mac and Linux.
Presenting data in an aesthetically pleasing way can be difficult, there are many different tools available for creating graphs and plots but many of the best are challenging to learn, expensive, or both. This post will show you a way of using the free R programming language along with the graphing service Plotly to create high quality plots, specifically when dealing with audio data.

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.

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.

Have you ever covered your ears with your hands to protect yourself from loud noise? That’s the closest to natural hearing protection that we’ve got, but just how much does it reduce the sound pressure level reaching your ear? And what’s the best method? This experiment aims to find out.
