Tinnitus activity in the limbic system and autonomic nervous system, thus increasing tinnitus awareness and annoyance. There are two types of tinnitus: "subjective tinnitus" and "objective tinnitus". Tinnitus is usually subjective, meaning that there is no sound detectable by other means. Subjective tinnitus has also been called "tinnitus aurium", "non-auditory" or "non-vibratory" tinnitus. In very rare cases tinnitus can be heard by someone else using a stethoscope, and in less rare – but still uncommon – cases it can be measured as a spontaneous otoacoustic emission (SOAE) in the ear canal. In such cases it is objective tinnitus, also called "pseudo-tinnitus"

Starting in 1980, the association has granted close to $6 million dollars in funding for tinnitus research. Many of these researchers have gone on to receive larger grants from the National Institutes of Health (NIH) based on ATA-funded research. Contributions to the association also go towards advocacy work in Washington, D.C. The ATA was created as resource for the under served tinnitus community.
