The human body is remarkably good at getting used to the environment around it. You’ve probably experienced this if you’ve ever gone to a matinee and emerged from the dark theater into sunshine. Your eyes sting, so you squint and shield your face until they adjust to the bright sunlight.
In the same way, the body can grow accustomed to constant noise. With repeated exposure to traffic, leaf blowers, construction, loud music, crowded restaurants, fitness classes and sporting events, you can become accustomed to loud environments. Over time, what once seemed unusually loud may barely register.
