Do you sometimes hear a shrill ringing sound but no one else appears to hear it? If you hear that infrequently, that’s just normal. Tinnitus, or the name of the condition, goes away after a second. It is typically brought on by psychological condition, or when you have heard a distressing news recently or if you are becoming worried about work or school. This can vanish if you adapt a new lifestyle. You would need to consult a medical professional, though, if the condition is already serous.
