At what age would you recommend a screening test for hearing loss?
Each participant completed a screening test for hearing ability, in which pure tones of 430, 2000, and 4096 Hz were presented to either left or right ear with varying intensity (software Presentation v14.2, http://www.neurobs.com/ [ 5]).
The threshold for defining a positive screening test for hearing loss varied across studies: 26 [ 38], 30 [ 36], 35 [ 35, 42, 44] or 40 [ 33, 34, 37, 39, 40] dB HL (Decibel Hearing Loss) while Lin and collegues [ 41] and Tatli and colleagues [ 43] did not report any threshold.
This paper describes the development of a speech-in-noise test for hearing screening and surveillance in Brazilian Portuguese based on the evaluation of suprathreshold acuity performances.
WVT is an easily applicable screening test for hearing impairment in general medicine.
This paper described the development of a test of suprathreshold acuity in noise in the Brazilian Portuguese language, that is, the SUN (Speech Understanding in Noise) test, a user-operated speech-in-noise test for hearing screening and surveillance, already available in the English, Italian, German, and French languages.
Visual acuity test was done using a Snellen chart and bed side testing for hearing performed using a 512 Hz tuning fork.
In a way, this figure is misleading because the SEM image is of an immature hair bundle at P4 and the tests for hearing function are performed much later (P14 and onwards).
One hour following the second day of salicylate administration a post treatment-ASR was recorded followed by ABR testing for hearing thresholds.
A total of 98.91% (10983/11104) of newborn babies were tested for hearing impairment at the first inpatient screening, ≤48 hours after birth.
