【英语时差8,16】耳鸣的困扰（下）（在线收听）

 Now, there’s no cure for tinnitus, but there are some good treatments. In fact, in recent years audiologists have come up with some ingenious therapies. One of these involves using music to trick the brain into muting or at least lowering the volume on tinnitus. Basically, the audiologist embeds musical tracks with a frequency specially designed to mask and cancel out the patient’s tinnitus. The patient then listens to the music for a few hours every day. And over several months, the frequency in the music causes the brain’s audio cells to rewire themselves in a way that makes the tinnitus less audible. So the ringing is technically still there, but over time it fades.
