Hi that is certainly possible. Also if the individual was in the military on active duty he may have sustained a hearing loss or shift. A third possibility that might have occurred is that some part of his system needs to "break in" again. Speakers and some capacitors are possible candidates for this behavior. I don't notice dramatic changes in anything except speakers, but others may be more sensitive to such changes in their gear.
