Topological acoustics are popping up in Nature and Science, is it really useful?
Traditional absorption, transmission and reflection applications are very useful, are they interesting enough? If not, how can we make them interesting again?
Would like to hear more opinions from everyone?
Thanks
It really depends on what you define as interesting or cool. There are a lot of fascinating areas in acoustics including the design of metamaterials (these are also applied to deviate earthquakes from critical structures), acoustic levitation and ongoing projects on the use of acoustic waves for the generation of Mach effects in the field of space propulsion! Personally, I have an interest in the construction of acoustic and ultrasonic devices therefore I find very interesting everything that concerns aspects of the production of acoustic sensors and the performance enhancement. In this field, lot of work is going on in the area of subwavelgth measurement and the development of one pixel acoustic cameras.
Reflection measurement are definetly of interest and in constant evolution, have a read to some tribo-acoustics papers for the measurement of friction, load and engine oil in-situ in running engines :)
Michele,
Thanks for your reply. Michele Schirru
You mentioned quite few of interesting topics, such as design of metamaterials, and acoustic levitation. I think I really like these two.
I found low frequency sound absorption (or shielding) is very challenging, but not well tackled yet. They are very useful in daily life.
Let's keep the discussion going.
Thanks!
Best,
