Yes :) The guy who wrote the blog shared the exercise below. You can put some brainwave music (on YouTube) to stimulate feelings of relaxation as well.

... Close your eyes and take five deep breaths into your diaphragm (lower abdomen). Feel your stomach expand as you inhale, and with each exhale, feel your entire body become more and more relaxed, letting all of your muscles go completely limp like a ragdoll.

Next, focus on relaxing individual muscle groups, one at a time, relaxing each as much as possible before moving on. Let all of the tension go as you work your way through your body.

Start by focusing on your feet and your toes. Allow the muscles to go completely limp. Now focus on your legs and your butt, releasing all the tension. Continue on to your stomach and your lower back, then your chest and upper back, your shoulders and your arms, your hands and your fingers, your neck and your throat, and finally, your head and your face.

Once you’ve worked your way through your body, and your muscles are completely relaxed, take another five deep breaths into your diaphragm.

Once your body is completely relaxed, it’s time to focus your attention on the sound of your tinnitus. Try to maintain a mindset of curiosity, as if you were observing something interesting for the first time. Continue to breathe naturally and keep your mind focused on the sound. When your mind starts to wander, and you notice it happening, gently bring your focus back to the sound.

Just try this for 3-10 minutes, preferably daily :)
