Check out how the mass loaded vinyl and sound blankets perform against low, medium and high frequency noises. For example, if the fundamental frequency is 50 Hz (also known as the first harmonic) then the second harmonic will be 100 Hz (50 * 2 = 100 Hz), the third harmonic will be 150 Hz (50 * 3 = 150 Hz), and so on. The typical, healthy young person can hear sounds between 60 and 20,000 Hz but that level of hearing sensitivity tends to reduce with age, especially at higher frequencies.
