From the pinna to the tympanic membrane, sound is increased by 5 to 15 decibels (dB) in the 2,000 to 4,000 Hertz (Hz) range due to the resonance of the auditory canal. The human ear is most sensitive to sound within this range and most vulnerable to damage from noises that are too loud.
When you knead dough, you help two proteins in wheat flour, gliadin and glutenin, form gluten. But flour also contains many other componentsâstarch, lipids, sugars, and enzymesâthat contribute to the consistency and nutritional value of bread.
There is a similar, yet not identical, protein in oats that some people react to. Wheat is a type of grain, and gluten is a protein that is found in wheat, barley, rye, and some other grains. Gluten is the component that gives bread dough its elasticity, and gives bread its chewy texture. Gluten is extracted from grains and used in the manufacturing of many foods.
