We achieve this by slowly increasing the amplitude of a given frequency and having the user press a button when they can hear the tone of the frequency under test. It found that the older people, even when tests suggest that they have normal hearing, still had greater difficulty than young people do, especially in noisy environments. Although this study had a small sample size, it was very cleverly designed: old and young participants were matched by IQ, Audiogram results, education, and other factors (to exclude extraneous affects). The incidence of clinically significant endometrial lesions associated with the presence of endometrial cells in Pap tests of women aged 40 years and older was very low. Considering this finding, women aged between 40 and 50 years with benign endometrial cells in a Pap test should undertake endometr … audiogram vector ranged between 5% and 15% for K = 12.

These findings corroborate literature findings and suggest that high-frequency audiometry may be used clinically for the early diagnosis of age-associated hearing loss. The levels are weighted with frequency relative to a standard graph known as the minimum audibility curve, which is intended to represent "normal" hearing. The threshold of hearing is set at around 0 phon on the equal-loudness contours (i.e. 20 micropascals , approximately the quietest sound a young healthy human can detect),  but is standardised in an ANSI standard to 1 kHz.  For humans, normal hearing is between −10 dB(HL) and 15 dB(HL), although 0 dB from 250 Hz to 8 kHz is deemed to be 'average' normal hearing. Hearing thresholds of humans and other mammals can be found with behavioural hearing tests or physiological tests used in audiometry.

Every increase of 10 decibels (10 dB) sounds twice as loud. 20 dB sounds twice as loud as 10 dB 40 dB sounds twice as loud as 30 dB and 8 times as loud as 10 dB (10 to 20 to 30 to 40 = 2 x 2 x 2 = 8). Normal hearing ranges from 0 to 20 dB in all frequencies.

It demonstrates how softly a person can hear certain sounds. The graph shows frequencies (pitches) and loudness (decibels). Behavioral Hearing Tests. Visual Reinforcement Audiometry: For children ages 5 months to 2 years. The child is taught to turn their The commonly stated range of human hearing is 20 to 20,000 Hz. 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. Though a ‘normal’ audible range for loudness is from 0 to 180dB, anything over 85dB is considered damaging, so we should try not to go there.
