Lowest and highest frequency to the human ear

Web29 sep. 2024 · It is given in a form of range (for example – 18Hz-22kHz). This range tells us the lowest and the highest frequency some audio device (speaker, headphones) can deliver. The frequencies within the range that a human ear can hear are called audible (or audio) frequencies and this range is known as our audio spectrum. WebSound frequency is usually expressed in units of cycles per second or Hz. Humans have a useful hearing range of approximately 20–20000 Hz, but are most sensitive to frequencies between about 1000 and 6000 Hz (for reference, the lowest and highest notes on the piano are 27.5 and 4186 Hz, respectively.)

WebConsequently, you should avoid extended exposure to decibel levels above 85 dB. In addition to decibel levels, harmful sound frequencies can also be damaging to human hearing. Low frequencies (under 20 Hz) and high frequencies (above 20,000 Hz) that humans cannot perceive can also affect the ear and have adverse effects on our health.
