Not a good thing...Since when does a professional ask someone to blow their noses so they can do a hearing test? Doesn't sound like an audiologist would request that...or any professional would offer to do any type of hearing tests. Anyone that needs to know what they can hear needs to have a clear passageway so that the tests can be done. If a person has a cold, flu, sinus infection or anything of that nature - the tests should be cancelled or rescheduled until the symptoms are gone and cleared up. The best outcomes and numbers will obtained when a person is able to hear through the ear canal and the bone conduction tests can be done to confirm what is happening with the sound waves.
