Tinnitus as a function of duration and etiology: counselling implications.

Based on the data of 528 tinnitus patients, information is presented concerning: (a) conditions and/or activities that affect tinnitus severity, (b) tinnitus symptoms as a function of etiology, and (c) changes in tinnitus symptoms as a function of time since onset. The four most common conditions and/or activities that reduce tinnitus severity were sleep, listening to TV/radio, being in noise, or being in quiet. Many conditions and/or activities increased tinnitus severity. The most common detrimental activities and/or conditions were noise exposure, being in a quiet place, emotional stress, loss of sleep, and physical exhaustion. Results also revealed that tinnitus loudness and severity increased as a function of years since onset. However, tinnitus pitch tended to remain stable. Meniere's patients experienced more annoyance, depression, and interference with sleep and also reported louder tinnitus than other etiologies. Tinnitus counselling should include: (a) informing patients that it is unlikely tinnitus annoyance will change dramatically, (b) alerting patients to the usefulness of tinnitus self-help groups, (c) helping patients to minimize time spent in activities and/or conditions where tinnitus severity is increased and to maximize time in activities and/or conditions where tinnitus severity is decreased, and (d) stressing the avoidance of noise exposure because of the relationship between noise-induced hearing loss and tinnitus.
