Bubbling tinnitus caused by change in head position

open access: yesClinical Case Reports, 2021
Because the density of air is lower than the effusion, air bubbles can be passively moved by a head position change, causing a bubbling sound in the affected ear.

Research on Spectral Characteristics of Wake Bubble Curtain

open access: yes水下无人系统学报, 2023
When the ship is sailing, the bubble curtain is generated due to the stirring of the propeller and the influence of the air and sea water, and a wake is formed at the tail of the ship. At present, the research on wake optics mainly focuses on macroscopic
