## Narrative

Annual hearing tests on 9/14/06 showed EE had STS Shift of 10 or more but <25. Retested on 11/8/06 & received paperwork 11/29/06 indicating he now had STS >25. He's indicated hearing loss runs in family so I've scheduled evaluation by Audiologist 12/13/06 to determine if shift is work related. Amendment: Audiologist & Dr. determined hearing loss is result of blockage in ear canal.
