Article headline says "ultrasonic" (frequencies too high for human perception, such as bat chirps) but article describes very low-frequency sound, sometimes called "infrasonic." Strange error for a supposedly tech-oriented site to make.
No it doesn't. The first part of the article is about Extremely Low‐Frequency and Low‐Intensity Electromagnetic Field (ELF‐EMF) stimulation, the second part about transcranial ultrasound. Two links from the article, one about each technique:
