Within the framework of the LAC 2022, I had the opportunity to attend this great event that only takes place once a year. It so happened that this time it was the city of Buenos Aires, Argentina, where the AURAL sound school is located. It was a rewarding experience where I was able to meet both fellow students and teachers, for my part I was able to contribute by carrying our prototype of absorption gradient diffuser (DIGRA), designed between colleagues from Argentina and Chile, belonging to the Acoustics and Perception Department from our student section. In a way that we could transport it either by sky or by land without major inconvenience, we talked about that context when out prototype must be assembled and placed allowing to add the absorbent material on its back, and thus be able to install it on any type of surface to carry out the future measurements in a conditioned room or a semi anechoic chamber. Afterwards we're going to do meausurements on an acoustics laboratory. As you can see, we can also have time to take a silly photo of some of us with parts of the prototype!
