I rely on my yellow foam ear plugs. Yesterday, I had tickets to Antique Road Show. Noise and voices everywhere. My ear plugs worked great. They do not limit my ability to communicate.

My sound sensitivity has lessened slowly over the years. I believe it is a package issue. Sound can not be separated from other stimulations. If I moderate other sensory stimulation, I have more tolerance for sound. Studies show that the brain can quickly allocate sensory processing resources so the sense needing more processing bandwidth is allocated that bandwidth. The 'untrained' brain can make these allocation changes in 12 hours. Over time, this allocation can become very flexible. I can stop, close my eyes and greatly improve my auditory processing and tolerance.
