Hearing range describes the frequency range that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 15.000 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies ...
The absolute threshold of hearing (ATH), also known as the absolute hearing threshold or auditory threshold, is the minimum sound level of a pure tone that an average human ear with normal hearing can hear with no other sound present. The absolute threshold relates to the sound that can just be heard by the organism.
Key Takeaways: Human hearing spans from 20 Hz to 20,000 Hz. Hearing conversation in noise is challenging, especially when the noise has a similar frequency to human speech.
It is approximately the quietest sound a young human with undamaged hearing can detect at 1,000 Hz. [15] The threshold of hearing is frequency dependent and it has been shown that the ear's sensitivity is best at frequencies between 1 kHz and 5 kHz. [15] Humans typically have a lower hearing threshold for their own names.
Infrasound arrays at monitoring station in Qaanaaq, Greenland.. Infrasound, sometimes referred to as low frequency sound or subsonic, describes sound waves with a frequency below the lower limit of human audibility (generally 20 Hz, as defined by the ANSI/ASA S1.1-2013 standard). [1]
Infrasound is sound at frequencies lower than the low frequency end of human hearing threshold at 20 Hz. It is known, however, that humans can perceive sounds below this frequency at very high pressure levels. [1]
The human ear can nominally hear sounds in the range 20 to 20 000 Hz. The upper limit tends to decrease with age; most adults are unable to hear above 16 000 Hz. Under ideal laboratory conditions, the lowest frequency that has been identified as a musical tone is 12 Hz. [6] Tones between 4 and 16 Hz can be perceived via the body's sense of touch.
