| Abstract | Conductive hearing loss simulations attempt to estimate the speech understanding difficulties of children with otitis media with effusion (OME). However, the validity of this approach has not been tested. The research aim was to investigate whether a simple, frequency-specific, attenuation-based simulation of OME-related hearing loss is able to reflect the actual effects of conductive hearing loss on speech perception. METHODS: School aged children with OME-related hearing loss, and also children with normal hearing, were recruited. The two groups were gender and age matched. Pure tone threshold differences at octave frequencies from 125 to 8000 Hz for every participant pair were used as the simulation attenuation levels for the normal-hearing children. The Mandarin Hearing in Noise Test was utilized for the speech stimuli. Percentage correct answers were acquired at four signal-to-noise ratios (SNR) that are considered representative of classroom listening conditions. Reception thresholds
for speech (RTS) in quiet and in noise were obtained using adaptive protocols. RESULTS: Forty-one pairs of children were recruited. Analysis showed a significant correlation for RTS in quiet between
children with OME and children with simulated hearing loss, r = .47, p < .01. No significant correlation was discovered for RTS in noise or for percentage correct answers. Percentage correct answers obtained at favourable SNRs were not significantly different between the two groups. In adverse listening conditions, speech recognition in children with hearing loss was significantly better than for children with simulated hearing loss with t (77) = 2.04, p < .05 at 0 dB SNR and t (77) = 2.82, p < .01 at -5 dB SNR. CONCLUSIONS: Simple, frequency-specific, attenuation-based simulation may reflect the effects of OME-related hearing loss on speech perception in quiet but not in noise. The difficulties of children in unfavourable listening conditions may be overestimated using this method. |
