In 14 patients (male: 5, female: 9) with acute acoustic impairment, ranging from 17 to 38 years old (mean, 27.1 years) in age, the most common symptom was tinnitus in all cases (all 18 ears), followed by hearing loss in 9 cases (10 ears), aural fullness in 6 cases (6 ears) and autophonia in 2 cases (2 ears). Transient dizziness was seen in 2 cases. It was most noticeable in this investigation that in 5 cases these symptoms had appeared after the concerts at a certain multipurpose indoor stadium. As far as we know, these cases have not been reported in the Japanese literature. It was also noted that the low tone-impaired type of audiogram, which has been reported to be infrequent in this clinical entity, was most frequently (6 cases) seen in this series. We also paid attention to the fact that tinnitus tended to remain even in the ears in which hearing recovered to the normal range.
