Wolfgang Hiller, Ph.D., University of Mainz, Germany, and Gerhard Goebel, M.D., from Roseneck Center of Behavioral Medicine, Prien, Germany, analyzed data from a mail survey composed of two parts: a questionnaire to assess perceived annoyance and a comprehensive screening questionnaire that grades loudness. The total of 4,995 individuals who responded had an average age of 56 years and was 42 percent female and 58 percent male. A total of 4,971 individuals accurately completed the loudness survey. Of these, 407 (8.2 percent) rated their condition as grade I (weak degree of tinnitus loudness), 2,964 (59.6 percent) as grade II (medium degree of tinnitus loudness) and 1,600 (32.2 percent) as grade III (strong degree of tinnitus loudness). Annoyance scores were available for 4,982 people of whom 1,957 (39.2 percent) were categorized as mildly distressed, 1,189 (23.9 percent) as severely distressed and 637 (12.8 percent) as most severely distressed. Most of those with grade I conditions reported mild tinnitus distress, those with grade II conditions were split and approximately two-thirds of those in grade III reported having severe or very severe distress, indicating a moderate correlation between loudness and annoyance.
