Reading these numbers

Appliance ranges are wide because they cover different models: the bottom of a range is a quiet modern machine, the top an older or noisier one. Many sources give no distance, so treat the numbers as what you would hear in the same room. The ones to watch are those that end up close to a child’s ear: noisy toys (measured 10 cm from the ear), white noise machines on a cot rail and hand dryers at a toddler’s height. Noise, children and pets.
