A research team from Penn State University has conducted a new study that sheds light on why frequent ringing or other phantom sounds in the ears—known as tinnitus—often serve as one of the earliest indicators of impending hearing loss. Details of the scientific work were shared by the portal Penn State Health.
In the United States, according to the national Centers for Disease Control and Prevention, approximately 13% of the adult population experiences hearing difficulties. Among individuals over the age of 65, this rate rises to 27%. Tinnitus has been officially diagnosed in 10% of adults.
This hearing disorder develops as a result of damage to the hair cells in the cochlea of the inner ear. These cells are responsible for converting sound waves into nerve signals. As these cells gradually fail, the brain must compensate for the resulting deficit of auditory information by generating these phantom sounds.
Audiologists emphasize that the risk of hearing damage arises from sound exposure exceeding 85 decibels, a level often encountered at concerts, construction sites, and when using lawnmowers or various other tools. Researchers consider the combination of tool noise and loud music through headphones to be particularly hazardous.
A complete cure for tinnitus is not yet possible; medicine can only alleviate its effects through a specialized treatment approach that combines counseling and sound therapy.
