In children, when too many sound sources bombard the brain, the brain reacts by “tuning out” what seems less important. Multiple sounds inundate us every day, all day long. Learn more about selective hearing and how to deal with it to improve communication in your family.
What Is Selective Hearing?
Picture a typical weekday morning: The television news is on, the birds are chirping, the coffee pot is gurgling, the dishwasher is running, your spouse is talking to you, and you are listening to the sounds of the shower upstairs to make sure your child is getting ready for school. Despite all these sounds, you immediately hear the traffic report that concerns the route you normally drive. The brain handles sensory information automatically at lower levels of awareness. When sensory information (including sound) comes in, the brain processes it by:
Filtering and enhancing — such as alerting to your name being called.Selective Perception — such as not being able to enjoy a delicious meal when anxious.Sensory Contrast — such as the difference in brightness of a candle in a dark room versus the same candle outside in the sunshine.Prioritizing — such as the feel of your clothes is unimportant unless there is a tag abrading the skin.
This processing is necessary and can be helpful; one example of these processes at work can be seen in the cocktail party effect. In a group of people, with multiple conversations and noise in all directions, the brain is able to tune into the person that is the most important to hear and ignore the other conversations going on. Another example is the way a new mom seems to develop super hearing when it comes to hearing her baby cry and will wake up immediately but sleep through other, louder sounds.
