The location of the hole (perforation) in the eardrum also effects the degree of hearing loss. If severe trauma (e.g. skull fracture) disrupts the bones in the middle ear which transmit sound or causes injury to the inner ear structures, the loss of hearing maybe quite severe.

If your goal is to build muscle, aim for 8 to 12 reps per set. However, there are a few exceptions to this rule. When training your lower body, aim for 12-15 reps per set. The same goes for your abs. Whether you want size or strength, perform 3 to 5 sets. Rest for 60 to 90 minutes between sets.
