Human ear sound

Under ideal laboratory conditions, humans can hear sound as low as 12 Hz 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. The human auditory system is most sensitive to frequencies between 2,000 and 5,000 Hz. 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 Several primates, especially small ones, can hear frequencies far into the ultrasonic range. Measured with a 60 dB SPL signal, the hearing … Meer weergeven Cats have excellent hearing and can detect an extremely broad range of frequencies.

The compression and rarefaction of these waves set this thin membrane in motion, causing sympathetic vibration through the middle ear bones (the 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. As with humans, some dog breeds' hearing ranges narrow with age, such as the German shepherd and miniature poodle. … Meer weergeven WebThe eardrum is a cone-shaped membrane that separates the external ear from the middle ear and inner ear. It is also known as the tympanic membrane. When sound reaches the eardrum, it vibrates in response to the pressure fluctuations of the acoustic wave. The middle ear contains three small bones – the hammer, anvil, and stirrup.
