You can use a machine to try to block out the noise of tinnitus. The machine can be small and worn near the ear, like a hearing aid. Or the masking sound can be played through a speaker. Masking devices are sometimes called white noise machines.
Some people distract themselves from their tinnitus by playing music or having the TV or radio on in the background.
There hasn't been much research about masking devices.    And some of the research that has been done isn't very good.  However, lots of people try masking devices, and doctors often recommend them alongside other treatments.
One small study found that 4 in 10 people improved while using a masking device, compared with 3 in 10 people getting a dummy (placebo) treatment.  However, 1 in 10 people got worse tinnitus while using a masking device. The study looked at just 17 people, so may not be very reliable.
