Effect of the type of noise and the spatial separation of the speech recognition measured using the HINT
Bibliographic record
Abstract
La perception de la parole dans le bruit est l'une des tches auditives les plus importantes pour assurer une communication efficace dans la vie de tous les jours.Plusieurs tests cliniques ont t dvelopps pour quantifier les difficults de perception de la parole dans un bruit continu.Il est toutefois bien reconnu que les bruits rencontrs dans la vie de tous les jours sont davantage fluctuants et que les priodes moins intenses de bruit permettent l'auditeur de mieux capter certaines parties du message verbal.Le prsent projet a comme objectif d'valuer la performance de jeunes adultes avec audition normale au HINT, sous couteurs et en champ libre, en utilisant une version modifie du bruit standard continu en y insrant un taux d'intermittence de 16 Hz.Des donnes normatives ont t tablies avec ce bruit modifi pour les trois conditions de bruit du HINT, soit Bruit Avant, Bruit Droit et Bruit Gauche.Lorsque compars aux normes avec le bruit continu, les seuils de rception de la parole s'amliorent de 13 dB et 10 dB sous couteurs et de 9 dB et 6 dB en champ libre lorsque le bruit est positionn en frontal et sur le ct, respectivement.L'avantage binaural (diffrence de seuils entre bruit frontal et bruit ct) sous couteurs est d'environ 89 dB et 5 dB pour le bruit continu et intermittent, respectivement, et de 67 dB et 34 dB en champ libre pour le bruit continu et intermittent, respectivement.Les donnes normatives maintenant disponibles pour un bruit intermittent de 16 Hz permettront d'ajouter au HINT clinique au moins une condition de bruit noncontinu afin de mieux documenter la capacit des individus, particulirement ceux avec perte auditive, prendre avantage des priodes de silence pour reconnatre la parole. Speech perception in noise is one of the most important tasks for proper communication in everyday listening situations.Multiple clinical tests have been developed to quantify difficulties understanding speech in continuous noise.However, it is now well recognized that everyday noises are fluctuating in nature, and that segments with lower noise levels allow listeners to more easily capture speech elements.The objective of the current study is to evaluate the performance of young adults with normal hearing on the HINT, under headphones and in the sound field, using a modified 16Hz interrupted version of the standard continuous noise.Normative data for the new intermittent noise was established in each of the three HINT noise conditions: Noise Front, Noise Right and Noise Left.When compared to performance with continuous noise, threshold improvements of 13 dB and 10 dB under headphones and of 9 dB and 6 dB in the sound field are noted in the Noise Front and Noise Side conditions, respectively.The binaural advantage (the threshold difference between the Noise Front and the Noise Side conditions) under headphones was approximately 89 dB and 5 dB for the continuous and intermittent noises, respectively, and 67 dB and 34 dB in the sound field for continuous and intermittent noises, respectively.Now that normative data is available for the modified 16Hz intermittent noise, it could be useful to add at least one testing condition of intermittent noise to the clinical HINT.Such further testing would allow documentation of one's ability to take advantage of "dips" in noise to increase speech recognition, particularly in individuals with hearing loss.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
