Imagine a future world where society realizes the full benefits of sound waves and phonons—sound’s quasiparticle counterpart. A world where millions live quietly in large cities; where personalized sound therapy accelerates healing from physical trauma; where non-invasive deep brain sound stimulation treats neurological disorders; where waste heat is recycled into useful energy; and where compact devices process sound-encoded information in parallel. A New Frontiers of Sound (NewFoS) is creating a new science of sound to accelerate technological advances that lead us to this future vision.
Technological and societal challenges to be addressed by NewFoS: (A) Sound levels in cities will continue to negatively impact populations along transportation corridors  unless viable solutions are found; (B) Sound-based therapies such as the ultrasound acceleration of bone fracture healing are still at an empirical stage; (C) Heat loss in engineered systems is one of the greatest challenges for technological societies; and (D) Progress in wireless, information and communication technologies is needed beyond existing acoustic wave devices, and variations thereupon, based on 1960-70’s technologies that are plagued by loss [10-12].
The current understanding of sound is rooted in a 300-year scientific history. New ways of looking at sound have received minor attention and require a paradigm shift for this major scientific revolution—analogous to classical vs. quantum mechanics, or Newtonian gravitation vs. general relativity. Sound waves and phonons require a supporting medium for propagation. This makes them extremely complex and prone to losses: the two long-standing technological obstacles that have prevented the human race from realizing the full beneficial uses of sound waves and phonons. To overcome these obstacles, NewFoS is creating a new science of sound, grounded in the universal principles of symmetry breaking and interactions, by shifting paradigms to a framework of localized and geometrically entangled sound waves. The paradigm-changing scientific foundations laid by NewFoS maximize the positive impacts of sound waves and phonons on society through breakthroughs such as:
- Improved public health by mitigating the effects of noise in urban and industrial environments. Learn more about how NewFoS could benefit public health.
- Enriched individual health from revolutionary sound-based precision diagnostic and therapeutic technologies. Learn more about how NewFoS could benefit health.
- Suppressed heat loss for efficient energy production and use. Learn more about how NewFos could benefit energy.
- Innovative phonon computing or highly nonlinear signal processing devices to enhance human–machine communication. A new science of sound is the grand challenge to achieve the inherent, unexplored potential of sound waves and phonons for the benefit of society.
