http://www.cochlea.org/en/hear/human-auditory-range The human auditory system is most sensitive to frequencies between 2,000 and 5,000 Hz. [9] Individual hearing range varies according to the general condition of a human's ears and nervous system. The range shrinks during life, [10] usually beginning at around the age of eight with the upper … Meer weergeven 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 … Meer weergeven In humans, sound waves funnel into the ear via the external ear canal and reach the eardrum (tympanic membrane). The compression Meer weergeven Cats have excellent hearing and can detect an extremely broad range of frequencies. They can hear higher-pitched sounds than humans or most dogs, detecting frequencies … Meer weergeven Bats have evolved very sensitive hearing to cope with their nocturnal activity. Their hearing range varies by species; at the lowest it can be 1 kHz for some species and for … Meer weergeven 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 organism's nominal hearing range. Behavioural … Meer weergeven Several primates, especially small ones, can hear frequencies far into the ultrasonic range. Measured with a 60 dB SPL signal, the hearing … Meer weergeven 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.
