Expert Answer:

Yes you are right. But it  differs from child to child. Generally , Children can hear higher frequencies which adults cannot hear.As the age  increases the upper limit drops gradually . At the age of about 70 years, this frequency might even fall to 8KHz. This phenomenon is called presbycusis.
