About the sound difference between your ears and your DB meter. Not all folks perceive sound the same way. Some are sensitive to specific frequencies that fail to annoy the bulk of the population. Where you disagree with the meter both may be correct as something is being registered by the meter that is being ignored by you. Go with your ears.
Personal example. Furnace blower motor replaced. It's in the basement but I can't have a quiet read in the living room because of the noise that no one else in the family hears. Dealer replaces the motor with another of the same make/model. Same only-I-have problem. Delare replaces motor with one by another manufacturer and problem solved.
Trust your ears - we own these things for years.
