A new study led by Professor Yasuhiro Suzuki from Nagoya University in Japan is testing a unique sound mask that may help alleviate depression and cognitive disorders like dementia. The mask, designed to be worn for a few minutes daily, emits low-frequency sounds perceived by the skin rather than the ears. Early trials show promise in improving memory performance among elderly patients. The University of London is also starting its own tests, with potential applications for trauma treatment in conflict areas like Ukraine.
