Signal-To-Noise Threshold with and without Hearing Aid

Abstract: We determined the necessary signal-to-noise threshold for 50% sentence discrimination in 130 patients with sensorineural hearing disorders with and without a hearing aid, as well as the minimum monosyllable discrimination loss without hearing aid. A significant correlation coefficient was found to exist of the signal-to-noise threshold with vs. that without hearing aid (r = 0.61), and between the minimum discrimination loss and the signal-to-noise threshold with hearing aid (r = 0.38). These differences in the… Show more

“…3,5,15,[17][18][19] . In order to obtain the intensity levels found in the free field, we used the following strategy that has been already employed in prior investigations: [20][21] -Noise calibration: we adjusted the audiometer's VU meter in the 0 position and measured the noise SPL in the free field of the A scale of the SPLM.…”

“…In order to calibrate the stimuli in the free field, we selected the A scale in the SPLM, with quick responses, which is more used to measure continuous noise and to determine extreme values of intermittent noise, and it is also the scale used by most researchers in this field. 3 , 5 , 15 , 17 , 18 , 19 .…”

“…Saying that a poor TJR makes conversation difficult is another way to say that noise interferes with hearing a desired signal. Since hearingimpaired listeners generally require higher TJRs than normal hearing listeners (Plomp, 1978(Plomp, , 1986Tillman, Carhart, & Olsen, 1970;Van Tasell, 1993;Welze-Mueller & Sattler, 1984), the problem often has been made worse by simple amplification schemes that perceptually seem to increase the jammers disproportionately more than the desired targets.…”
