Sound has a significant influence on all of life in a multitude of ways. Not only does music make us feel good, but sound has also proven to have a healing influence on a number of human conditions.
On a fundamental level, sound is vibration. “When sound waves move through the air, each air molecule vibrates back and forth, hitting the air molecule next to it, which then also vibrates back and forth.” (Science World) These vibrations and oscillations are measured in cycles called Hertz (Hz). The number of times per second that a sound wave’s cycle repeats is referred to as the sound's frequency. Sound frequencies have proven to have an influence on human health and behavior depending on the particular frequency being used.
In this article, we will focus on the power of 40Hz. 40Hz is a “low” frequency in the audible spectrum which ranges from around about 20 Hz to 20 kHz.
A pitch of 40 Hz, heard as a low pitch close to the lowest ‘E’ on the piano, is not a singular stimulation, but rather exerts 40 stimuli per second. When this stimulus is applied to the ears as sound waves it ‘drives’ a brain response through the auditory system.

40Hz has proven to be particularly beneficial to the brain. According to studies, our brain cells communicate at a frequency of 40Hz. Research has found this frequency to demonstrate "promising" results in terms of increasing cognition, clarity and alertness. They also found 40Hz to demonstrate healing implications for Alzheimer’s Disease, fibromyalgia, tinnitus, and potentially for reducing pain and inflammation.
