Ultrasonic Frequency Spectrum: Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Although this limit varies from person to person, it is approximately 20 kilohertz (20,000 hertz) in healthy, young adults and thus, 20 kHz serves as a useful lower limit in describing ultrasound Frequency Response Chart. A great way to see how a speaker, buzzer, or microphone can reproduce these different frequencies is with the frequency response chart. In general, buzzers carry a narrower frequency range because they are only tasked with outputting an audible tone, whereas speakers offer a wider range to recreate sounds and voice An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is in the band audible to the average human, the human hearing range.The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch.. The generally accepted standard hearing range for humans is 20 to 20,000 Hz. In air at atmospheric pressure, these represent sound waves with. 963 hertz sound frequencies are associated with activation of the pineal gland and higher spiritual development.
