The Perendale originated in New Zealand from crossing the Border Cheviot with the Romney breed. They are an open-faced, medium-framed breed that produces bright, lofty, long-stapled, medium-wool fleeces. Developed as an easy-care sheep, they are both hardy and highly adapted to marginal forage-producing areas.
It depends how badly the eardrum is ruptured. Mine ruptured a couple of years ago from a bad ear infection, and it took me at least 3 weeks to get the ringing out of my ear. Depends a bit of how good you protect the ear from pressure changes; usually between 2 - 4 weeks. If you really do have an ear problem, do NOT mess 'round.
A perforated eardrum is a hole or tear in the eardrum. It can be uncomfortable, but usually heals within a few weeks or months provided your ear is kept dry and thereâs no infection. The eardrum, also known as the tympanic membrane, is a thin layer of tissue that separates the outer ear from the middle ear.A hole in the eardrum can be caused by: 1  a middle ear infection, if pus builds up inside your ear and puts pressure on your eardrum.2  an injury to the eardrum, such as a severe blow to the ear or poking an object such as a cotton bud deep into the ear. 3  a sudden loud noise, such as a loud explosion.our GP may prescribe antibiotics if your perforated eardrum was caused by an infection or if there is a risk that an infection will develop while your eardrum heals. You can reduce your risk of developing an infection by keeping your ear dry until it's healed.
