Hi, as you are aware by now, that the cause for your tinnitus is the
perforated ear drum. This has to heal for the tinnitus to resolve. This may take time
and this depends on the size of the perforation and if there are any other causes like persisting infections. Sometimes "white noise" may help suppress the sound so that it's less bothersome using an electronic device. Please discuss this with your doctor am sure he will provide further assistance. Regards.
