Sound-masking devices
The fact that tinnitus is more prominently perceived in silent settings, is applied in this treatment strategy. Here, devices which produce pleasant ambient sounds are used to mask out the tinnitus sound perception. Any sort of subtle noise, music, or nature sounds can be used. These devices are available in different forms. Some are portable, others can be worn in the ears. Another type of this device can be installed in the room or lounge etc.
Another form of sound masking devices use modified sounds to filter the tinnitus ringing. These devices use sound not as ambient background music, but as tonal frequencies which match the specific tinnitus pattern. The acoustic properties of tones from the device are altered in such a way that they become inaudible for the patient. So the ongoing therapy is not consciously perceived, which further relieves the burden of therapy and tinnitus itself. These devices can be used intermittently in cases of setting-specific tinnitus. There is also a significant improvement over time. By effectively relieving tinnitus when it gets worse, and giving enough off-time for the patient to actively tolerate mild tinnitus, these devices promote habituation. Now hearing aids come equipped with this sound therapy features for tinnitus.
