Normal curve of hearing
WebAll studies showed that in populations not exposed to loud sounds, hearing declined minimally with age. A <10 decibel audiometric decrement with age, not meeting the technical definition of hearing loss, may be normal physiological aging. A 25-40 decibel decrement is not. 2.

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 considerable variation between individuals, especially at high frequencies, and a gradual … Ver mais 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. Ver mais 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 from 55 Ver mais 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 other species the highest reaches up to 200 kHz. Bats that can detect 200 kHz cannot hear … Ver mais In humans, sound waves funnel into the ear via the external ear canal and reach the eardrum (tympanic membrane).

However, research in the 1960s demonstrated that determinations of equal-loudness made using pure tones are not directly relevant to our perception of noise.
