The commonly stated range of human hearing is 20 to 20,000 Hz. [5] [6] [note 1] Under ideal laboratory conditions, humans can hear sound as low as 12 Hz [7] and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea . [8] See more Hearing range describes the range of frequencies 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 20 to 20,000 Hz, although there is … See more Several primates, especially small ones, can hear frequencies far into the ultrasonic range. Measured with a 60 dB SPL signal, the hearing range for the Senegal bushbaby is … See more The hearing ability of a dog is dependent on breed and age, though the range of hearing is usually around 67 Hz to 45 kHz. As with humans, … See more A basic measure of hearing is afforded by an audiogram, a graph of the absolute threshold of hearing (minimum discernible sound level) at various frequencies throughout an … See more In humans, sound waves funnel into the ear via the external ear canal and reach the eardrum (tympanic membrane).

Web2 Oct 2024 · Most healthy adults have an average hearing range of between 20 and 20,000 hertz. Sounds below 20 Hz are called infrasound, and those above 20,000 Hz are called … WebThe limit of human hearing is approximately 20kHz, which hence requires a sample rate of approximately 40Khz. This is why CDs are sampled at 44Khz. i.e. each second of recording in a CD contains 44,000 measurements of the highest possible frequency contained in the recording.
