Audible Frequency is characterized as a periodic vibration whose frequency is audible to the average human. It is the property of sound that most determines pitch and is measured in hertz (Hz).
The generally accepted standard range of audible frequencies is 20 to 20,000 Hz, although the range of frequencies individuals hear is greatly influenced by environmental factors. Frequencies below 20 Hz are generally felt rather than heard, assuming the amplitude of the vibration is great enough. Frequencies above 20,000 Hz can sometimes be sensed by young people. High frequencies are the first to be affected by hearing loss due to age and/or prolonged exposure to very loud noises.
Frequencies below 20 Hz are generally felt rather than heard, assuming the amplitude of the vibration is great enough.
The main idea is to be able to visualize a non audible frequency.
This consists of four main elements.
1. Using a digital frequency generator application.
2. Connecting computer to an amplifier.
4. Creating a non Newtonian substance/fluid.
5. Applying the substance into the speaker’s cone.
