Hearing researchers at Macquarie University have shown that listeners rapidly learn and adapt to the characteristics of acoustic spaces to improve their understanding of speech and have found evidence for the brain mechanisms involved in ‘listening to the room’.

Their findings also indicate the presence of a reverberation ‘sweet spot’ in which learning and adaptation are optimised.

Empowering national regulators to build the tools of a digital society takes focus for the 25th year of the ITU Global Symposium for Regulators

Thanks to a rotating platform, a new 3D metal printer can deposit and fuse metal powder in a single step, thereby working faster than conventional machines.

The system can process two different metals in a single operation, which streamlines manufacturing and minimises material waste.

A prototype was developed in just nine months and offers potential for application in aerospace and propulsion technology – in fact, in any area where there is a need for lightweight, roughly cylindrical objects.
