Equal loudness spl hl decibel scale4/17/2024 For the clinical application, the 2.1-dB difference between spondees and tones at equal loudness became a 12.1-dB difference when the stimuli were converted from SPL to HL. Equal-loudness levels were inferred from fitted loudness functions for the group. Results: When evaluated at the same SPL, speech-shaped noise was judged louder than vowels/spondees, which were judged louder than tones. Loudness predictions were obtained for the same stimuli by using a computational, dynamic loudness model. Participants listened monaurally through earphones. Method: Loudness magnitude estimation functions were obtained from 24 participants for pure tones (0.5 and 1.0 kHz), vowels, spondees, and speech-shaped noise as a function of level (20–90 dB SPL). N2 - Purpose: The purpose of this article is to examine explanations for pure-tone average–spondee threshold differences in functional hearing loss. © 2017 American Speech-Language-Hearing Association. We are grateful for Professor Brian Moore’s advice about implementing the dynamic loudnesss model for our conditions.

T1 - Pure-tone–spondee threshold relationships in functional hearing loss Furthermore, the dynamic loudness model was more accurate than the static model.", The recognition threshold for spondees is roughly 9 dB higher than the speech detection threshold persons feigning a loss, who base loss magnitude on loudness, do not consider this difference. Conclusions: Nearly all of the pure-tone average–spondee threshold differences in functional hearing loss are attributable to references for calibration for 0 dB HL for tones and speech, which are based on detection and recognition, respectively. Furthermore, the dynamic loudness model was more accurate than the static model.Ībstract = "Purpose: The purpose of this article is to examine explanations for pure-tone average–spondee threshold differences in functional hearing loss.
