Abstract: Objective To explore the clinical, auditory and psychoacoustic characteristics of patients with tinnitus accompanied by auditory hypersensitivity and to explore its effects on patients. Methods Forty-two patients with tinnitus and hyperacusis who were admitted to the Department of Otorhinolaryngology, Second Affiliated Hospital of Guangzhou Medical University from March 2015 to March 2017, were detected the pure tone audiometry, tinnitus psychoacoustic characteristics, loudness discomfort level(LDL). Results There were 24 cases of tinnitus as the first chief complaint group(group A)and 18 cases of hyperacusis as the first main complaint group(group B). Tinnitus tone was given priority to with pure tone, frequency was given priority to with high frequency, and the loudness is mostly ≤5dB SL. Patients with hyperacusis is characterized by excessive attention or deliberate avoidance of normal environmental sounds, accompanied by irritability, palpitations, panic, fear, wearing earplugs, and dare not going out. LDL at frequencies between 0.125 and 8kHz were detected, and there was no significant difference in LDL between the two groups at the same frequency(P>0.05). Conclusion The severity of auditory hyperacusis cannot be judged by the loudness discomfort threshold; clinical tinnitus and auditory allergy are often accompanied, and attention should be paid to its influence on the work, life, sleep and mood of patients. The evaluation scale suitable for China's national conditions should be formulated and used.
