Abstract Objective: The aim of the present study was to study patterns in the extended spectrum of the human hearing (0.125 to 20 kHz) in order to obtain reference thresholds. Then, we compare our values with existing results at extended high-frequencies (8 to 20 kHz) in an attempt to establish new standards for potential international adoption. Design: A prospective study in a group of otologically healthy subjects. Study sample: A total of 645 subjects aged between 5 and 90 years were… 

Extended high-frequency audiometry: hearing thresholds in adults

The EHFA is found to be a highly sensitive method for early detection of hearing loss, with hearing thresholds decreasing as soon as 35 years of age, and in males, the hearing thresholds grew with age more rapidly than in women.

Earphones in extended high-frequency audiometry and ISO 389-5

The results are in good agreement with previous studies of hearing thresholds using the same and other earphones, and are relevant for the international standard for the calibration of audiometric equipment in the 8 to 16 kHz frequency range, ISO 389-5.

Extended high-frequency audiometry in healthy adults with different age groups

Hearing thresholds at EHF from 9 to 20  kHz were more sensitive than at frequencies below 8 kHz for hearing measurement, and aging inversely affected hearing ability at E HF in healthy population.

Hearing threshold levels for an otologically screened population in Spain

The hearing threshold levels in the present study were higher (poorer) than the ones provided by ISO 7029 (2000), suggesting that the thresholds listed in ISO 7028 (2000) may be too restrictive, and could be useful in formulating theISO 7029 update.

Equivalence and test–retest reproducibility of conventional and extended-high-frequency audiometric thresholds obtained using pure-tone and narrow-band-noise stimuli

Thresholds in the conventional and EHF ranges showed good test-retest reproducibility, but differed between stimulus types, which should be taken when comparing pure-tone thresholds with NBN thresholds especially at these frequencies.

High-Frequency Audiometry for Early Detection of Hearing Loss: A Narrative Review

A literature search was conducted to see whether high-frequency audiometry (HFA) could be used for the early detection of hearing loss and showed higher hearing thresholds in respondents aged under 31 years following the use of personal listening devices (PLDs) for longer than 5 years.

Results from this study suggest that the thresholds listed in ISO 7029 (2000) may be too restrictive, and could be useful in formulating theISO 7029 update.

Extended high-frequency audiometry in research and clinical practice.

EHF audiometry in the clinic presents with no particular difficulty, the biggest obstacle being lack of specialist equipment, and with the development of international guidelines and standards, it is likely that EHF testing will become widespread in future.

Human auditory sensitivity for the frequencies 8, 10, 12, 16, 18, and 20 kHz was examined in a group of 41 female university students and the approach described in the present study provided reliable thresholds and was found to be clinically feasible.

Average thresholds in the 8 to 20 kHz range in young adults.

The sound-pressure level thresholds in the extended high-frequency range were measured in 25 non-hearing-impaired young adults from 20 to 29 years of age and two notable points were found: one that the threshold reached a plateau above 18 kHz, and the other that it decreased slightly at 12 kHz.

Extended high-frequency thresholds in older adults.

EHF thresholds of older listeners with normal hearing at conventional audiometric frequencies were substantially higher than the thresholds reported for younger listeners, and results indicated that thresholds above 8 kHz can be measured in older listeners within a clinically acceptable +/- 10 dB test-retest range.

Average thresholds in the 8 to 20 kHz range as a function of age.

The regression line analysis of the sound-pressure thresholds reveals that the thresholds at 8-10 kHz tend to increase more at higher frequencies as subject age increased above 30 to 39 years, and those at 14-19 kHz increase translationally with increase of age.

Threshold of hearing (0.125-20 kHz) in children and youngsters.

Only a few audiograms, the majority being in the youngest age group, were found to be a result of possible noise damage, and in the extra-high-frequency range, a systematic decrease in sensitivity was found for the two older groups compared to the 10-year-old children at frequencies higher than 14 kHz.

Normative thresholds in the 8- to 20-kHz range as a function of age.

Using a prototype high-frequency audiometer, auditory thresholds in the 8- to 20-kHz range were obtained from 240 subjects ranging in age from 10-60 years, and an analysis of variance revealed significant effects of frequency, age, and sex, and a significant frequency-by-age interaction.

Test-Retest Reliability of Pure-Tone Thresholds from 0.5 to 16 kHz using Sennheiser HDA 200 and Etymotic Research ER-2 Earphones

Evaluated the intrasession test-retest reliability of pure-tone thresholds measured in the 0.5–16 kHz frequency range for a group of otologically healthy subjects using Sennheiser HDA 200 circumaural and Etymotic Research ER-2 insert earphones to compare the data with existing criteria of significant threshold shifts related to ototoxicity and noise-induced hearing loss and repeatability was similar for both transducer types.

Extended high frequency audiometry in pre-school children.

The hearing thresholds could be more reliably determined in the older children and were 5 dB better than in the younger ones (< 5 years).

High-frequency hearing thresholds in young adults using a commercially available audiometer.

Normative high-frequency thresholds could not be recommended for clinical use due to the very large intersubject threshold variability and future research should concern intrasubject threshold reliability and variability rather than specifying intersubject normative thresholds.

Presbyacusis—hearing thresholds and the ISO 7029

The purpose of this study was to analyse the changes inpure-tone hearing thresholds with age, and found that the ISO 7029 normative a coefficient in females may beset too low compared to the authors' sample in the lower frequencies, leading to an underestimation of hearing thresholds in ON females.
