8th-20th rows is the noisiest area in the plane?why?

Every day, hundreds of laptops are broken due to the fact that the passenger of the front seat tilts sharply, which breaks the computer on her lap seated from behind.

The first row of the business class is considered the most convenient. There's more room for the feet, no one sits in front of you, you're the first who gets food, drinks, newspapers, you get blankets and pillows. For those who travel with young children, you can attach a cradle for babies to the wall and put a child seat.

8-20th rows is the noisiest area in the plane, all the noise of engines and turbines is concentrated.
