Summary of "Screening for hearing loss in the Hong Kong Cantonese-speaking elderly using tablet-based pure-tone and word-in-noise test."

The present study aimed to establish the test-retest reliability and validity of a tablet-based automated pure-tone screening test and a word-in-noise test as hearing screening tools for older Hong Kong Cantonese-speaking adults. It was a cross-sectional within-subject study. One hundred and thirty-two older adults participated in this study, and 112 of them completed the automated pure-tone screening test, word-in-noise test, and conventional pure-tone audiometry. Pure-tone threshold of 40 dB HL at each of the tested frequencies including 500, 1000, 2000 and 4000 Hz, obtained with conventional pure-tone audiometry was set as the pass/refer criterion, for the calculation of sensitivity and specificity of the tablet-based screening tools. The tablet-based automated pure-tone screening test yielded a sensitivity of 0.93 and specificity of 0.82, while the word-in-noise test yielded a sensitivity of 0.81 and specificity of 0.70 with the cut-off chosen as a speech reception threshold of -3.5 dB signal-to-noise ratio. Both tests require around 3 minutes to be completed on both ears. The tablet-based pure-tone test and word-in-noise test are reliable and valid to be used as screening tools for hearing loss in the Hong Kong Cantonese-speaking elderly.

Medical and Biotech [MESH] Definitions

The former British crown colony located off the southeast coast of China, comprised of Hong Kong Island, Kowloon Peninsula, and New Territories. The three sites were ceded to the British by the Chinese respectively in 1841, 1860, and 1898. Hong Kong reverted to China in July 1997. The name represents the Cantonese pronunciation of the Chinese xianggang, fragrant port, from xiang, perfume and gang, port or harbor, with reference to its currents sweetened by fresh water from a river west of it.

A geographic area of east and southeast Asia encompassing CHINA; HONG KONG; JAPAN; KOREA; MACAO; MONGOLIA; and TAIWAN.

Hearing loss due to exposure to explosive loud noise or chronic exposure to sound level greater than 85 dB. The hearing loss is often in the frequency range 4000-6000 hertz.

Hearing loss due to disease of the AUDITORY PATHWAYS (in the CENTRAL NERVOUS SYSTEM) which originate in the COCHLEAR NUCLEI of the PONS and then ascend bilaterally to the MIDBRAIN, the THALAMUS, and then the AUDITORY CORTEX in the TEMPORAL LOBE. Bilateral lesions of the auditory pathways are usually required to cause central hearing loss. Cortical deafness refers to loss of hearing due to bilateral auditory cortex lesions. Unilateral BRAIN STEM lesions involving the cochlear nuclei may result in unilateral hearing loss.

Hearing loss due to damage or impairment of both the conductive elements (HEARING LOSS, CONDUCTIVE) and the sensorineural elements (HEARING LOSS, SENSORINEURAL) of the ear.
