Speech Identification

The physical characteristics of hearing aids are modified when the instrument is coupled with an earmold and fitted to an ear canal. This study compares the electroacoustic characteristics of four specific earmold variations with behavioral speech audiometric tasks in five normal-hearing and seven sensorineural-hearing-loss subjects. Speech-Bekesy thresholds were obtained under each earmold condition with continuous discourse for detectability, intelligibility, most comfortable loudness, and tolerance. Speech discrimination ability was evaluated with the Modified Rhyme Test in three signal-to-noise ratio conditions. Significant differences in test scores attributable to earmold modification were difficult to demonstrate, in spite of the fact that substantial variations in the ear inserts were readily apparent in both structural and electroacoustics analysis.

Modified Rhyme Test

INTRODUCTION: In response to the urgent need for safe aircrew respiratory protection due to the COVID-19 pandemic, three small descriptive evaluations were conducted with aircrew and air traffic controllers (ATC) that assessed the impact of mask use on safety and performance onboard rotary wing aircraft.METHODS: A series of evaluations assessed aircrew performance using the 3MTM Model 1860 N95 respiratory protection mask, two aviation-specific cloth mask prototypes, and a commercial off-the-shelf aviation-specific cloth mask. The series of evaluations included different sets of subjects consisting of up to five Black Hawk helicopter aircrew members, air traffic control (ATC), and 12 CH-47 aircrew members. The Modified Rhyme Test was used to measure speech intelligibility and was administered in the UH-60 among crewmembers of the same aircraft, between pilots of different aircraft, and between the pilots and ATC. Measures of workload, usability, comfort, and pulse oximetry were also administered.RESULTS: Results from the Modified Rhyme Test indicated that all subjects scored greater than 80% accuracy given the proper microphone positioning relative to the mask. With respect to workload, NASA-TLX total scores for the perform radio communications task was 50.83.DISCUSSION: Despite an elevated perceived degree of workload on the communications flight task, results from the speech intelligibility test indicated that performance was maintained within the acceptable range as defined by MIL-STD-1474E, Design Criteria Standard Noise Limit. This abbreviated evaluation suggests that the face masks tested are safe for use by helicopter aircrew under the conditions tested.Cave KM, Kelley AM, Feltman KA, Gerstner JA, Stewart JL, Crowley JS.

Modified Rhyme Test

Four lists of the Modified Rhyme Test (MRT) were administered to 9 normal-hearing and 50 impaired-hearing subjects. The stimuli were spoken by a male speaker with test conditions designed to yield 96, 83, 75, and 96% correct responses by normal listeners. Normal subjects performed within the expected normal limits. Impaired-hearing subjects had significantly lower scores and did not show the proportional decrease for the most difficult condition. The performance of subjects grouped by degree of hearing loss showed that increasing noise did not affect MRT scores differentially, nor did MRT scores decrease significantly with increasing speech reception thresholds (SRTs). When a slight amount of noise accompanied the MRT, a significant relationship was shown with clinically obtained W-22 scores. Correlational analysis among five measures of speech-discrimination ability and six measures of threshold sensitivity supported other studies with regard to the frequency region important for the perception of monosyllabic stimuli at suprathreshold levels.
